OBJECTIVE: To inform resource allocation toward a continuum of care for youth at risk of suicide, we examined unplanned 30-day readmissions after pediatric hospitalization for either suicide ideation (SI) or suicide attempt (SA).
METHODS: We conducted a retrospective cohort study of a nationally representative sample of 133,516 hospitalizations for SI or SA among 6- to 17-year-olds to determine prevalence, risk factors, and characteristics of 30-day readmissions using the 2013 and 2014 Nationwide Readmissions Dataset (NRD). Risk factors for readmission were modeled using logistic regression.
RESULTS: We identified 95,354 hospitalizations for SI and 38,162 hospitalizations for SA. Readmission rates within 30 days were 8.5% for SI and SA hospitalizations. Among 30-day readmissions, more than one-third (34.1%) occurred within 7 days. Among patients with any 30-day readmission, 11% had more than one readmission within 30 days. The strongest risk factors for readmission were SI or SA hospitalization in the 30 days preceding the index SI/SA hospitalization (adjusted odds ratio [AOR]: 3.14, 95% CI: 2.73-3.61) and hospitalization for other indications in the previous 30 days (AOR: 3.18, 95% CI: 2.67-3.78). Among readmissions, 94.5% were for a psychiatric condition and 63.4% had a diagnosis of SI or SA.
CONCLUSIONS: Quality improvement interventions to reduce unplanned 30-day readmissions among children hospitalized for SI or SA should focus on children with a recent prior hospitalization and should be targeted to the first week following hospital discharge.
Coordinating Complex Care: Mission Impossible?

Kelly Miranda Photography: "There's Enough Room for Everybody"
A forgotten camera from a high school photography class set Kelly MacNiven on the path to owning her own business, Kelly Miranda Photography. Her husband, Casey, had enjoyed the class he'd taken years before and he'd kept the camera. It stayed underneath the bed collecting dust until MacNiven found it before they left on their honeymoon to Mexico. "We brought the camera with us," said MacNiven. "I was documenting my husband and the landscape and anything I could see. I enjoyed it and had a knack for it."
Born and raised in Durango, Colo., MacNiven met Casey at Fort Lewis College, where she was studying biology. They formed a band while in college, with Casey on guitar, and MacNiven singing and playing piano and guitar. When their drummer graduated and moved to Denver, Casey and MacNiven were ready for a change. After checking out Denver, they heard about Austin. "We wanted to get out of the snow," explained MacNiven, who moved to Texas with Casey in 2008. "We ended up loving the place. It was a really cool city and a fun place to be in your early twenties. It provided the change we were looking for."
With the move, MacNiven, while waiting tables, decided to invest in a camera at the local Best Buy. She paid it off within a year and decided to go back to school for photography. She found a program in Austin. "I was more of fine arts photographer when I started, doing obsrtact images," shared MacNiven. "If I wanted to make money, I would have to do portraits and weddings, which was fine, because I enjoyed that, too. It was an interesting journey. I didn't know I was going to make a business out of it until I started going to school and realized I didn't want to wait tables anymore."
The program focused on the technical aspects of photography, with a strong business aspect. MacNiven took classes on accounting and photography studio management, which included units about getting insurance, creating a business plan, and how to set prices. "I felt like I was pretty prepared by the time I graduated to not only be a photographer, but what my prices were," shared MacNiven. "I still made my mistakes. I at least had that knowledge beforehand and knew, going into it, that there were going to be certain obstacles."
She learned the practical aspects of doing business, including how to weigh costs against profit and how to plan accordingly. She explained that many people think that if the business makes $100,000, then the photographer makes $100,000, which isn't how business works. Costs have to be included to the intended salary, and the salary has to be set. "If I want to make $40,000, then that's $40,000 on top of what my expenses are," explained MacNiven. "It was nice that my teachers taught me to value what I'm worth and to value my art. In the end, you're spending all this time to make this art for people and you need to know what your time is worth."
MacNiven encourages anyone trying to start a business to do the research and know the numbers necessary to cover necessary costs and earn a decent salary. There are calculators online that help determine costs and the equivalent income needed. "Know how much you want to make and charge that from the beginning," MacNiven suggested. "I didn't really plan for how much time each thing was going to take me and how much it was going to cost me to run my business. That's my biggest piece of advice – nailing your numbers."
After graduation, MacNiven and Casey had their son, Carter, and decided to move back to Durango in 2013 to be closer to her family. She had already started her photography business in Austin, and the move meant that she had to start over. "And I started over again and again," added MacNiven. "I feel like I've started over so many times. It's constantly in a state of growth for me."
MacNiven had chosen an ideal client base with related branding, but tax season brought a rude awakening. "I realized I'd made maybe 10 dollars an hour doing what I've done," said MacNiven. "I'd worked so hard. I realized I just couldn't do it for that wage anymore. I wasn't going to able to support my family on that. I had to rebrand myself and work with a whole different type of client."
She realized she wanted to add prints, and then she decided to add a studio space. "It is an important part of my artistic process to see the photos all the way to the finished print product," explained MacNiven. "I wanted a more hands-on approach to the customer experience."
Three years later, MacNiven is seeing the results of her work as she focuses on family portraits and wedding sessions, with additional projects such as headshots and buildings. "It's been great, and every year I'm growing a little bit more," she said. "I'm seeing my numbers double and it's promising that I'm actually able to make a living this way and be able to support my family. I think I've settled on how I'm going to do things. I don't think I'm going to have to rebrand or start over anymore because it seems to be doing really well."
She's also found support in the small business community in Durango. She attends the local Chamber events for networking opportunities, and has developed a good rapport with other local photographers. "We can all help each other out and there's enough room for everybody," said MacNiven. "There's enough business to go around. We don't need to be competitive. It works and we all help each other out and it's a great community of artists and business owners making sure there's enough room for all of us, doing what we love to do."
As her business continues to grow, she's also found ways to give back and support her community. She recently concluded a fundraising drive for Project Merry Christmas. For a session fee of $175, which included Christmas cards and an ornament, MacNiven offered portraits. She raised $1,000, which will help two to three families with food, clothing and presents for the holiday season. "I try to do something every year to support a local family," she said. "I think it's really important we all try to give back. I've been in the position where I've needed help with health insurance. There are lot of people out there struggling to make it. It's important to help each other and build each other up. For people who can't get their basic needs met, it's huge we help out with that, so if I can, I'm going to do it. I like that I can use my art and photography talent to give back in some way. For me to be able to use that in a way that helps people is really important. I feel like we should all be doing that in some way or another as small business owners."
MacNiven has found, despite the challenges and struggles she's had, that it's worth it owning her business and pursuing her craft. "One of the biggest things that holds people back from making a living at their art is that fear factor," admitted MacNiven. "It's scary. It's pretty huge. For me, the risk is not going to outweigh the benefit. It's so incredible when you get that feeling that you're finally there and you're finally supporting yourself from your art. You don't need that other job. It's such a good feeling. I can buy groceries and pay rent. When I was in school, photographers came in and talked to classes. They really inspired me, hearing their stories. They can do it, and if they can do it, so can I."

Glamour and Glitz: Perks of the Senior Model Program with Allison Ragsdale Photography
Senora Robinson has seen her friends enter the Senior Model Program with Allison Ragsdale Photography for the past five years. "I always thought her photos were amazing," Senora shared. "I was pretty well integrated in the modeling arena, so I wanted to make sure I had a great photographer for my senior photos. I was recommended my junior year by one of my senior friends. She has great photos."
As a child, Senora started modeling when she received encouragement and guidance from a photographer after a family shoot. Since then, she has moved more towards the business side of the fashion industry, but modeling has remained a personal goal.
Senora is headed to fashion school next fall, after graduating this spring. "I would love to keep modeling," revealed Senora. "I would love to be a Victoria's Secret Pink Model. That's my life goal."
Senora, now an intern with Allison, works with Allison and her husband, Matt, every week, assisting Matt with marketing, sending out marketing materials or helping organize contests, and going on location with Allison to shoots. She completes projects such as Snapchat stories, which Allison posts on Instagram, and helps with flash adjustments, poses and wardrobe. "I help bring revenue, excitement and a different perspective," Senora explained. "We're trying now to look at the point of view of the senior and the person who's already gone through the Senior Program so we can make it better for the up and coming seniors."
She's also seen how clients transform from feeling uncomfortable and vulnerable to confident and relaxed. "Allison just makes everything so easy and doesn't have you do anything you're uncomfortable with," Senora said. "She lets you take charge of your shoot which is really awesome. She makes it really fun and comfortable."
Allison allows the session to be customized, which includes listening to music, or incorporating outfit changes. "It's super personalized to you," Senora explained. "She's lighthearted, really fun and really easy to talk to and be around and it makes it really fun for people doing family, wedding, and senior photos. Everyone loves Allison. It's really great."
Senora had been asked by several other photographers in town to join their senior program, but she wanted to work with Allison. "I chose Allison, hands-down, no question, because I knew the program and the way she runs it," said Senora. "It will be even better with the 2017 Program, especially with the adjustments we're making."
Valuing her input as a senior who has completed the program, Allison and Matt asked for suggestions on how enhance the experience. While Senora has noticed that potential clients are nervous about the cost, she has experienced herself that participation in the program is worth much more than the money value. Included are multiple shoots, which can include headshots, couture session, family session, senior session, and custom sessions, depending on the model level a senior chooses. Hair and make-up are also included. "It's really worth all of it," Senora said, "and it's documented the end of junior year to the end of senior year and you change a lot, so it's cool to document the entire time instead of just senior photos."
Then there are the relationships with Allison and Matt. "You get to know her and Matt very well, which is cool because they're such great people," shared Senora. "It's an overall really fun experience. I would absolutely go back and do it again."

Making a House a Home: Family Portraits with Allison Ragsdale
The last time Pauline Ellis participated in a family photo, she was two years old. After getting married, having a daughter of her own and moving to Durango, Ellis first saw Allison Ragsdale's work at the Durango Recreational Center. "I thought, if I ever wanted a family portrait, I would look Allison up," Ellis shared.
Ellis's work for the United States Forest Service brought her to Durango. With a degree in civil engineering, Ellis is now the partnership coordinator for the San Juan National Forest, which relies on many partners to help care for the forest.
Ellis married her husband, Fred, in 1996, who also works for the Forest Service as a wildland firefighter and fuels technician. They met through mutual friends while Fred was living in Georgia and Ellis was in Arizona. The night before they were going on a backpacking trip with friends through the Smoky Mountains, a hurricane ripped through the area. "We weren't sure we'd be able to make the trip, but we were able to hike through downed trees," remembered Ellis, who has been with the Forest Service for 35 years. "It was fun."
Ellis and Fred's daughter, Brooke, graduated from high school earlier this year. She wanted her senior portraits taken by Allison, which came with a complimentary family session. "We were so pleased with those pictures," Ellis said of the senior portraits. "It was wonderful. My daughter tends to be pretty shy, and Allison, in a nice, unassuming way, was able to get these fabulous pictures of her. I was afraid she'd look the same in every picture and not smile, but she was able to get these wonderful poses of her."
They took advantage of the family portrait opportunity when her father, who lives in southern California, visited during Christmas last year. Ellis' mother had passed away, and with her father getting older, Ellis wanted to capture their family memories. "Like many other families for years, we've talked about doing a family portrait," Ellis admitted. "Other than a free portrait for our church directory, we haven't done pictures."
Ellis found that Allison was able to work magic with her stoic father and two small dogs. "She was able to get my dad to smile," marveled Ellis. "She's amazing with animals, she was amazing with my senior father, she was great with my daughter and with my camera-shy husband. We couldn't be more pleased."
Matt and Allison's assistance didn't end after the photo sessions. "We have so little experience with professional photography," Ellis explained, "This is where we appreciated both Matt and Allison. Matt spent so much time with us in the studio, selecting the photos and the displays. They came out to our house and helped us find the right place in our home, and hung the photos for us. There was never any hard sell whatsoever. They just followed up the photo shoot with a session to show us the pictures, the different products available and let us select what suited our family the most."
Ellis saw not only Matt's expertise in selecting the perfect portraits, but how those portraits personalized their recently remodeled home. "I'm not good at designing or decorating," Ellis demurred. "Most things that hang on the wall are pieces of my life. Having those photos there just captures everything we wanted about making our house a home."
Now, Brooke has moved to Washington State for college, and her parents are facing an empty nest, albeit a wonderfully decorated one. "I think my husband is going to spend a lot of time staring at her pictures and pining for her," Ellis explained, "It will help ease the transition of empty nesting."

Senior Model Program Offers Life-Long Friendships and Cherished Moments
Lisa and Peter Marshall first met Matt, the husband half of Allison Ragsdale Photography, when he was teaching math at the Durango High School. As a freshman, their oldest daughter, Colin, was shy. Lisa knew she was a good student, but had concerns about her socially. "I remember going to my first conference and sitting down with Matt," Lisa shared. "I asked how she was doing, socially, and he just looked at me like I was crazy."
She found out that Colin talked nonstop in class. "It made me feel good that she felt that comfort level with him to have those interactions and come out of her shell," shared Lisa, who has three daughters and one son. "Matt had great relationships with the kids, even if he didn't have them all in class."
Two years later, Colin applied for the Allison Ragsdale Photography Senior Model Program. Through the program, during their senior year, students are the face of Allison Ragsdale Photography online and in their community while they model for new location shoots, portfolio building and collaborative projects and are featured on prints and canvases locally and nationally. In addition to the business cards they can hand out with their images printed on them, they receive various other perks, such as points that can be applied to prints or other products.
Colin's participation in the Senior Model Program began a life-long friendship. "I don't consider them photographers who work for me. I really consider them our friends," shared Lisa. "The photos are so beautiful, but what's more important to me is that they bring out a very natural beauty in my children. The pictures I love aren't standard pictures of them for their senior photos. They're looking down. They're looking away. That's what I love. They're the moments we're going to cherish forever."

Class X Chapter 1 – Chemical Reactions and Equations Science
Why should a magnesium ribbon be cleaned before burning in air?
Magnesium is very reactive metal. When stored it reacts with oxygen to form a layer
magnesium oxide on its surface. This layer of magnesium oxide is quite stable and
prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned
by sand paper to remove this layer so that the underlying metal can be exposed into air.

(ii) Write the reaction of the substance 'X' named in (i) above with water.
(i) The substance 'X' is calcium oxide. Its chemical formula is CaO.
(ii) Calcium oxide reacts vigorously with water to form calcium hydroxide (slaked lime).
Why is the amount of gas collected in one of the test tubes in Activity 1.7 double of the
amount collected in the other? Name this gas.
Water (H2O) contains two parts hydrogen and one part oxygen. Therefore, the amount of
hydrogen and oxygen produced during electrolysis of water is in a 2:1 ratio. During
electrolysis, since hydrogen goes to one test tube and oxygen goes to another, the
amount of gas collected in one of the test tubes is double of the amount collected in the
Why does the colour of copper sulphate solution change when an iron nail is dipped in it?
When an iron nail is placed in a copper sulphate solution, iron displaces copper from
copper sulphate solution forming iron sulphate, which is green in colour.
Therefore, the blue colour of copper sulphate solution fades and green colour appears.
Give an example of a double displacement reaction other than the one given in Activity
Sodium carbonate reacts with calcium chloride to form calcium carbonate and sodium
chloride.
In this reaction, sodium carbonate and calcium chloride exchange ions to form two new
compounds. Hence, it is a double displacement reaction.

(b) Chlorine gas and iron hydroxide are produced.
(c) No reaction takes place.
(d) Iron salt and water are produced.
(a) Hydrogen gas and iron chloride are produced. The reaction is as follows:
What is a balanced chemical equation? Why should chemical equations be balanced?
A reaction which has an equal number of atoms of all the elements on both sides of the
chemical equation is called a balanced chemical equation.
The law of conservation of mass states that mass can neither be created nor destroyed.
Hence, in a chemical reaction, the total mass of reactants should be equal to the total
mass of the products. It means that the total number of atoms of each element should
be equal on both sides of a chemical equation. Hence, it is for this reason that chemical
equations should be balanced.
Translate the following statements into chemical equations and then balance them.
(a) Hydrogen gas combines with nitrogen to form ammonia.
(b) Hydrogen sulphide gas burns in air to give water and sulphur dioxide.
(c) Barium chloride reacts with aluminium sulphate to give aluminium chloride and a
precipitate of barium sulphate.
(d) Potassium metal reacts with water to give potassium hydroxide and hydrogen gas.
Balance the following chemical equations.
Write the balanced chemical equations for the following reactions.
(a) Calcium hydroxide + Carbon dioxide → Calcium carbonate + Water
(b) Zinc + Silver nitrate → Zinc nitrate + Silver
(c) Aluminium + Copper chloride → Aluminium chloride + Copper
(d) Barium chloride + Potassium sulphate → Barium sulphate +
Write the balanced chemical equation for the following and identify the type of reaction
in each case.
(a)Potassium bromide (aq) + Barium iodide (aq) → Potassium iodide (aq) +
Barium bromide(s)
(b) Zinc carbonate (s) → Zinc oxide (s) + Carbon dioxide (g)
(c) Hydrogen (g) + Chlorine (g) → Hydrogen chloride (g)
(d) Magnesium (s) + Hydrochloric acid (aq) → Magnesium chloride (aq) + Hydrogen (g)
(a) Double displacement reaction
(b) ; Decomposition reaction
(c) Combination reaction
(d) Displacement reaction
What does one mean by exothermic and endothermic reactions? Give examples.
Chemical reactions that release energy in the form of heat, light, or sound are called
exothermic reactions.
Example: Mixture of sodium and chlorine to yield table salt
In other words, combination reactions are exothermic.
Reactions that absorb energy or require energy in order to proceed are called
endothermic reactions.
For example: In the process of photosynthesis, plants use the energy from the sun to
convert carbon dioxide and water to glucose and oxygen.
Why is respiration considered an exothermic reaction? Explain.
Energy is required to support life. Energy in our body is obtained from the food we eat.
During digestion, large molecules of food are broken down into simpler substances such
as glucose. Glucose combines with oxygen in the cells and provides energy. The special
name of this combustion reaction is respiration. Since energy is released in the whole
process, it is an exothermic process.
Why are decomposition reactions called the opposite of combination reactions? Write
equations for these reactions.
Decomposition reactions are those in which a compound breaks down to form two or
more substances. These reactions require a source of energy to proceed. Thus, they are
the exact opposite of combination reactions in which two or more substances combine to
give a new substance with the release of energy.
Decomposition reaction:
Combination reaction:
Write one equation each for decomposition reactions where energy is supplied in the
form of heat, light or electricity.
(a) Thermal decomposition:
(b) Decomposition by light:
(c) Decomposition by electricity:
What is the difference between displacement and double displacement reactions? Write
In a displacement reaction, a more reactive element replaces a less reactive element
from a compound.
where A is more reactive than B
In a double displacement reaction, two atoms or a group of atoms switch places to form
new compounds.
Displacement reaction:
Double displacement reaction:
In the refining of silver, the recovery of silver from silver nitrate solution involved
displacement by copper metal. Write down the reaction involved.
What do you mean by a precipitation reaction? Explain by giving examples.
A reaction in which an insoluble solid (called precipitate) is formed is called a
precipitation reaction.
In this reaction, calcium carbonate is obtained as a precipitate. Hence, it is a
Another example of precipitation reaction is:
In this reaction, barium sulphate is obtained as a precipitate.
Explain the following in terms of gain or loss of oxygen with two examples each.
(a) Oxidation
(b) Reduction
(a) Oxidation is the gain of oxygen.
In equation (i), H2 is oxidized to H2O and in equation (ii), Cu is oxidised to CuO.
(b) Reduction is the loss of oxygen.
In equation (i), CO2 is reduced to CO and in equation (ii), CuO is reduced to Cu.
A shiny brown-coloured element 'X' on heating in air becomes black in colour. Name the
element 'X' and the black coloured compound formed.
'X' is copper (Cu) and the black-coloured compound formed is copper oxide (CuO). The
equation of the reaction involved on heating copper is given below.
Why do we apply paint on iron articles?
Iron articles are painted because it prevents them from rusting. When painted, the
contact of iron articles from moisture and air is cut off. Hence, rusting is prevented their
presence is essential for rusting to take place.
Oil and fat containing food items are flushed with nitrogen. Why?
Nitrogen is an inert gas and does not easily react with these substances. On the other
hand, oxygen reacts with food substances and makes them rancid. Thus, bags used in
packing food items are flushed with nitrogen gas to remove oxygen inside the pack.
When oxygen is not present inside the pack, rancidity of oil and fat containing food items
is avoided.
Explain the following terms with one example each.
(a) Corrosion
(b) Rancidity
(a) Corrosion:
Corrosion is defined as a process where materials, usually metals, deteriorate as a result
of a chemical reaction with air, moisture, chemicals, etc.
For example, iron, in the presence of moisture, reacts with oxygen to form hydrated iron
oxide.
This hydrated iron oxide is rust.
(b) Rancidity:
The process of oxidation of fats and oils that can be easily noticed by the change in taste
and smell is known as rancidity.
For example, the taste and smell of butter changes when kept for long.
Rancidity can be avoided by:
1. Storing food in air tight containers
2. Storing food in refrigerators
3. Adding antioxidants
4. Storing food in an environment of nitrogen
Class X Chapter 2 – Acids Bases and Salts Science
You have been provided with three test tubes. One of them contains distilled water and
the other two contain an acidic solution and a basic solution, respectively. If you are
given only red litmus paper, how will you identify the contents of each test tube?
If the colour of red litmus paper gets changed to blue, then it is a base and if there is no
colour change, then it is either acidic or neutral. Thus, basic solution can be easily
Let us mark the three test tubes as A, B, and C. A drop of the solution in A is put on the
red litmus paper. Same is repeated with solution B and C. If either of them changes
colour to blue, then it is basic. Therefore, out of three, one is eliminated. Out of the
remaining two, any one can be acidic or neutral. Now a drop of basic solution is mixed
with a drop of each of the remaining two solutions separately and then the nature of the
drops of the mixtures is checked. If the colour of red litmus turns blue, then the second
solution is neutral and if there is no change in colour, then the second solution is acidic.
This is because acidic and basic solutions neutralize each other. Hence, we can
distinguish between the three types of solutions.
Why should curd and sour substances not be kept in brass and copper vessels?
Curd and other sour substances contain acids. Therefore, when they are
kept in brass and copper vessels, the metal reacts with the acid to liberate hydrogen gas
and harmful products, thereby spoiling the food.
Which gas is usually liberated when an acid reacts with a metal? Illustrate with an
example. How will you test for the presence of this gas?
Hydrogen gas is usually liberated when an acid reacts with a metal.
Take few pieces of zinc granules and add 5 ml of dilute H2SO4. Shake it and pass the gas
produced into a soap solution. The bubbles of the soap solution are formed. These soap
bubbles contain hydrogen gas.
We can test the evolved hydrogen gas by its burning with a pop sound when a candle is
brought near the soap bubbles.
Metal compound A reacts with dilute hydrochloric acid to produce effervescence. The gas
evolved extinguishes a burning candle. Write a balanced chemical equation for the
reaction if one of the compounds formed is calcium chloride.
Why do HCl, HNO3, etc., show acidic characters in aqueous solutions while solutions of
compounds like alcohol and glucose do not show acidic character?
The dissociation of HCl or HNO3 to form hydrogen ions always occurs in the presence of
water. Hydrogen ions (H+) combine with H2O to form hydronium ions (H3O+).
The reaction is as follows:
Although aqueous solutions of glucose and alcohol contain hydrogen, these cannot
dissociate in water to form hydrogen ions. Hence, they do not show acidic character.
Why does an aqueous solution of an acid conduct electricity?
Acids dissociate in aqueous solutions to form ions. These ions are responsible for
conduction of electricity.
Why does dry HCl gas not change the colour of the dry litmus paper?
Colour of the litmus paper is changed by the hydrogen ions. Dry HCl gas does not
contain H+ ions. It is only in the aqueous solution that an acid dissociates to give ions.
Since in this case, neither HCl is in the aqueous form nor the litmus paper is wet,
therefore, the colour of the litmus paper does not change.
While diluting an acid, why is it recommended that the acid should be added to water
and not water to the acid?
Since the process of dissolving an acid in water is exothermic, it is always recommended
that acid should be added to water. If it is done the other way, then it is possible that
because of the large amount of heat generated, the mixture splashes out and causes
burns.
How is the concentration of hydronium ions (H3O+) affected when a solution of an acid is
diluted?
When an acid is diluted, the concentration of hydronium ions (H3O+) per unit volume
decreases. This means that the strength of the acid decreases.
How is the concentration of hydroxide ions (OH−) affected when excess base is dissolved
in a solution of sodium hydroxide?
The concentration of hydroxide ions (OH−) would increase when excess base is dissolved
in a solution of sodium hydroxide.
You have two solutions, A and B. The pH of solution A is 6 and pH of solution B is 8.
Which solution has more hydrogen ion concentration? Which of this is acidic and which
one is basic?
A pH value of less than 7 indicates an acidic solution, while greater than 7 indicates a
basic solution. Therefore, the solution with pH = 6 is acidic and has more hydrogen ion
concentration than the solution of pH = 8 which is basic.
What effect does the concentration of ions have on the nature of the solution?
Concentration of can have a varied effect on the nature of the solution. With an
increase in H+ ion concentration, the solution becomes more acidic, while a decrease of
H+ ion causes an increase in the basicity of the solution.
Do basic solutions also have ions? If yes, then why are these basic?
Yes, basic solution also has ions. However, their concentration is less as compared
to the concentration of OH− ions that makes the solution basic.
Under what soil condition do you think a farmer would treat the soil of his fields with
quick lime (calcium oxide) or slaked lime (calcium hydroxide) or chalk (calcium
carbonate)?
If the soil is acidic and improper for cultivation, then to increase the basicity of soil, the
farmer would treat the soil with quick lime or slaked lime or chalk.
What is the common name of the compound CaOCl2?
The common name of the compound CaOCl2 is bleaching powder.
Name the substance which on treatment with chlorine yields bleaching powder?
Calcium hydroxide [Ca (OH)2], on treatment with chlorine, yields bleaching powder.
Name the sodium compound which is used for softening hard water.
Washing soda (Na2CO3.10H2O) is used for softening hard water.
What will happen if a solution of sodium hydrocarbonate is heated? Give the equation of
the reaction involved.
When a solution of sodium hydrocarbonate (sodium hydrogencarbonate) is heated,
sodium carbonate and water are formed with the evolution of carbon dioxide gas.
Write an equation to show the reaction between Plaster of Paris and water.
The chemical equation for the reaction of Plaster of Paris and water can be represented
A solution turns red litmus blue, its pH is likely to be
(a) 1 (b) 4 (c) 5 (d) 10
(d) Bases turn red litmus blue and acids turn blue litmus red. Basic solution has a pH
value more than 7. Since the solution turns red litmus blue, its pH is likely to be 10.
A solution reacts with crushed egg-shells to give a gas that turns lime-water milky. The
solution contains
(a) NaCl (b) HCl (c) LiCl (d) KCl
(b) The solution contains HCl.
10 mL of a solution of NaOH is found to be completely neutralised by 8 mL of a given
solution of HCl. If we take 20 mL of the same solution of NaOH, the amount of HCl
solution (the same solution as before) required to neutralise it will be
(a) 4 mL (b) 8mL (c) 12 mL (d) 16 mL
(d) 16 mL of HCl solution will be required.
Which one of the following types of medicines is used for treating indigestion?
(a) Antibiotic
(b) Analgesic
(c) Antacid
(d) Antiseptic
(c) Antacid is used for treating indigestion.
Write word equations and then balanced equations for the reaction taking
place when −
(a) dilute sulphuric acid reacts with zinc granules.
(b) dilute hydrochloric acid reacts with magnesium ribbon.
(c) dilute sulphuric acid reacts with aluminium powder.
(d) dilute hydrochloric acid reacts with iron filings.
(a) Sulphuric acid + Zinc → Zinc sulphate + Hydrogen
(b) Hydrochloric acid + Magnesium → Magnesium chloride + Hydrogen
(c) Sulphuric acid + Aluminium → Aluminium sulphate + Hydrogen
(d) Hydrochloric acid + Iron → Ferric chloride + Hydrogen
Compounds such as alcohols and glucose also contain hydrogen but are not categorized
as acids. Describe an activity to prove it.
Two nails are fitted on a cork and are kept it in a 100 mL beaker. The nails are then
connected to the two terminals of a 6-volt battery through a bulb and a switch. Some
dilute HCl is poured in the beaker and the current is switched on. The same experiment
is then performed with glucose solution and alcohol solution.
It will be observed that the bulb glows in the HCl solution and does not glow in the
glucose solution.
HCl dissociates into H+ and Cl− ions. These ions conduct electricity in the solution
resulting in the glowing of the bulb. On the other hand, the glucose solution does not
dissociate into ions. Therefore, it does not conduct electricity.
From this activity, it can be concluded that all acids contain hydrogen but not all
compounds containing hydrogen are acids.
That is why, though alcohols and glucose contain hydrogen, they are not categorised as
acids.
Why does distilled water not conduct electricity, whereas rain water does?
Distilled water is a pure form of water and is devoid of any ionic species. Therefore, it
does not conduct electricity. Rain water, being an impure form of water, contains many
ionic species such as acids and therefore it conducts electricity.
Why do acids not show acidic behaviour in the absence of water?
Acids do not show acidic behaviour in the absence of water because the dissociation of
hydrogen ions from an acid occurs in the presence of water only. It is the hydrogen ions
that are responsible for the acidic behaviour.
Five solutions A, B, C, D and E when tested with universal indicator showed pH as 4, 1,
11, 7 and 9, respectively. Which solution is
(a) neutral?
(b) strongly alkaline?
(c) strongly acidic?
(d) weakly acidic?
(e) weakly alkaline?
Arrange the pH in increasing order of hydrogen-ion concentration.
(a) Neutral → Solution D with pH 7
(b) Strongly alkaline → Solution C with pH 11
(c) Strongly acidic → Solution B with pH 1
(d) Weakly acidic → Solution A with pH 4
(e) Weakly alkaline → Solution E with pH 9
The pH can be arranged in the increasing order of the concentration of hydrogen ions as:
11 < 9 < 7 < 4 < 1
Equal lengths of magnesium ribbons are taken in test tubes A and B. Hydrochloric acid
(HCl) is added to test tube A, while acetic acid (CH3COOH) is added to test tube B. In
which test tube will the fizzing occur more vigorously and why?
The fizzing will occur strongly in test tube A, in which hydrochloric acid (HCl) is added.
This is because HCl is a stronger acid than CH3COOH and therefore produces hydrogen
gas at a faster speed due to which fizzing occurs.
Fresh milk has a pH of 6. How do you think the pH will change as it turns into curd?
Explain your answer.
The pH of milk is 6. As it changes to curd, the pH will reduce because curd is acidic in
nature. The acids present in it decrease the pH.
A milkman adds a very small amount of baking soda to fresh milk.
(a) Why does he shift the pH of the fresh milk from 6 to slightly alkaline?
(b) Why does this milk take a long time to set as curd?
(a) The milkman shifts the pH of the fresh milk from 6 to slightly alkaline because in
alkaline condition, milk does not set as curd easily.
(b) Since this milk is slightly basic than usual milk, acids produced to set the curd are
neutralized by the base. Therefore, it takes a longer time for the curd to set.
Plaster of Paris should be stored in a moisture-proof container. Explain why?
Plaster of Paris (POP) should be stored in a moisture-proof container because Plaster of
Paris, a powdery mass, absorbs water (moisture) to form a hard solid known as gypsum.
What is a neutralization reaction? Give two examples.
A reaction in which an acid and base react with each other to give a salt and water is
termed as neutralization reaction. In this reaction, energy is evolved in the form of heat.
(ii) During indigestion (caused due to the production of excess of hydrochloric acid in the
stomach), we administer an antacid (generally milk of magnesia, which is
basic in nature). The antacid neutralizes the excess of acids and thus gives relief from
indigestion.
Give two important uses of washing soda and baking soda.
Two important used of washing soda and baking soda are as follows:
(1) Washing soda:
(a) It is used in glass, soap, and paper industries.
(b) It is used to remove permanent hardness of water.
(2) Baking soda:
(a) It is used as baking powder. Baking powder is a mixture of baking soda and a mild
acid known as tartaric acid. When it is heated or mixed in water, it releases CO2 that
makes bread or cake fluffy.
(b) It is used in soda-acid fire extinguishers.

Kara Sundlun and I took our daughter to her first concert, Katy Perry at the Mohegan Sun resort. The show was awesome. Perry played to her fans, and the light extravaganza and costume changes were nothing short of amazing. Best part of the night? The look of excitement on my daughter's face. Helena is a big Katy Perry fan, and even dressed as her for Halloween.
There were plenty of little girls there and some younger than our 7 year old. Times certainly have changed. I wish my parents had taken me to a Doors concert when I was Helena's age, but I actually didn't see my first concert until I was 15, J. Geils at the Boston Garden. Ditto in the age department for Kara, who went to see Poison at the Joe Louis Arena in Detroit.
One of the best concerts I've been to in a long time!! I'm glad you enjoyed the pictures!

XVIII (18 in Roman numerals) is the sixth studio album by Eighteen Visions. It was released on June 2, 2017. It is the band's first album in 11 years, following its breakup in 2007. It is also the band's first release on Rise Records. According to Metal Insider, the album sold 3,525 units in its first week and is the band's highest-charting effort to date. The album peaked at number 49 on the Billboard Top Current Albums chart. In a 2017 interview with LouderSound, James Hart stated that XVIII was the record he wanted to be remembered for, adding that the record really spoke for who the band is and who they always have been, and encompassed the sound that the band liked the most from each of its prior albums.

Background

In a 2021 interview on the podcast "Chattin' With Captain", James Hart explained that the band had attempted to reform twice before 2017: once in 2012 and once in 2014. Keith Barney and Hart had written a few songs together during this time. In 2016 Keith had approached Hart and asked if he'd like to finish the songs. Hart agreed and reached out to Trevor Friedrich and Ken Floyd to include them in the writing process. Floyd would decline based on his workload, but the trio got together and started to record some of the old and new songs. Originally reluctant to use the name Eighteen Visions for their new endeavor (as Floyd was not involved), they ultimately decided they'd like to play Eighteen Visions songs live, and that their new material sounded like Eighteen Visions, so they might as well use the name. The trio originally set out to create new a new album that would sound like a combination of their first five releases, but as the recording process continued they decided that they wanted their new effort to be heavy, as that was what they felt the band was.

Announcing its reunion, the band launched an official Instagram account on February 9, 2017. The account's first post featured the message "the countdown begins..." as well as the text "XVIII". Tagged in the account's first post were James Hart, Keith Barney, and Trevor Friedrich. All three members uploaded the same picture onto their respective private accounts as well.

On April 20, 2017, exactly ten years from the day of its farewell live performance, the band announced its sixth studio album, "XVIII", which would be released on June 2, 2017 via its new label Rise Records. The band also announced that it would perform its first show in ten years on June 2 at The Observatory in Santa Ana, California to celebrate the release of the record. Alongside this announcement was the band's first new song in 11 years, and the debut single for the album, "Oath". MetalSucks noted the song sounded like a more polished version of something that would be found on Until the Ink Runs Out, and was heavier than anticipated.

On May 9, 2017, the band released the second single from the album, "Crucified", via Loudwire. The song included a lyric video on YouTube. Similar to "Oath", the song was under two minutes in length and marked the return of heavy screaming as a prominent element of the band's sound. In an interview with Loudwire, guitarist Keith Barney noted the band felt they needed something fast, and the band hadn't written anything as fast as "Crucified" since Vanity. He also added that the breakdown in "Crucified" ended up being the first teaser for the album on the band's Instagram and "everyone lost their s--t" so the band were happy to be fully releasing the song as a single.

On May 25, 2017, the third and final single from the album, "The Disease, The Decline, and Wasted Time" was released.

On June 2, 2017, the band released a music video for the track "Live Again", which Barney noted in an interview with Loudwire was a tribute to the late Mick Morris, the band's former bassist.

In a June 2017 interview with Exclaim!, Barney revealed that founding member, guitarist Ken Floyd, could not take part in the reunion due to his full-time job as a tour manager for Zedd. He also reported that the band decided not to replace the late Mick Morris with any other bass players, primarily out of respect for him. Instead, his bass tracks will be used at live shows for the songs released prior to 2017. Barney noted that discussion of a reunion began in 2012 but dissolved due to Barney's blossoming career as a graphic designer. Discussion began again a few years later when Mick Kenney heard a demo of "The Disease, The Decline, and Wasted Time" in the car of Trevor Friedrich, who was also his roommate. Kenny convinced Friedrich to let him record the song and things snowballed into an EP, and then an album, from there.

On August 28, 2017, the band announced via its Instagram that Stick to Your Guns guitarist Josh James would become an official member of the band. James, formerly of Evergreen Terrace and Casey Jones, had supported the group as a live guitarist and had appeared in the music video for "Oath".

In a September 4 2017, interview with the Lead Singer Syndrome podcast, Hart revealed that the band contemplated reunion as early as 2010 and, later on, in 2013. However, the idea was eventually called off due to various reasons. It was also stated that the track "The Disease, the Decline, and Wasted Time" was written back then.

On October 18, 2017, the band released a music video for the song "Underneath My Gun". The video features Every Time I Die guitarist and professional wrestler Andy Williams. The video takes inspiration from the John Carpenter film They Live, with Andy assuming the role of Roddy Piper and the band portraying the alien scum. The song itself opens with a quotation from the movie.

A differential heat treatment is clearly visible in the differential hardness line approximately two thirds up the blade. This results in a soft, supportive spine and an extremely hard, long lasting edge. The bolster is integral -- a technique that, while common in production knives, is very rare in handmade knives due to the difficulty of implementation. The handle is formed from a solid piece of presentation grade walnut wood with a mammoth ivory ferrule. The knife has perfect balance and this ensures it is as much of a joy to use as it is to look at!

I had the privilege of attending the Lifeline Brass Blokes Awards in my hometown of Newcastle last night. The Awards recognise the spirit of 'blokes' who have been through adversity yet still find the time, courage and inspiration to give back to their community. As well as celebrate these men, the event raises awareness of men's mental health and suicide, plus raises funds for Lifeline Hunter Central Coast. It was a special night.
One of the unique features of the awards was the 'entertainment'. It involved a panel (in this case Mark Hughes, Kurt Fernley and Nic Newling) discussion where a few invited guests talked through their own experiences in dealing with adversity and how they gave back to their community. You may not be surprised why these awards appealed to me.
During the panel discussion, a comment by Nic really struck a chord with me. When asked about ways that we can 'help' someone with a mental health problem, he suggested listening is key. The secret he said was not to try to sort things out for the other person, instead focus on being present and attentive to the other person's situation and focus on listening.
Could it be that listening is one critical skill that we all need to focus on if our aim is to 'help' others? What lessons could we take from Lifeline about how to best help someone in a time when life doesn't feel worth living anymore?
This got me to thinking further about what does it mean to 'help'? Could what we think is 'help', actually be quite the opposite for those we think we are helping? What if our 'help' made things worse? What may be the outcome if we impose our 'help' on others who are not seeking the type of 'help' that we are offering? If we constantly focus on fixing other peoples problems, could it have the effect of contributing to their pain, as they feel helpless to fix things for themselves? Further, what could it mean for the resilience of others if we constantly impose our 'help' on them?
I had some good conversations last night, none better than with my friend John who has many years experience 'helping' others in this situation and knows a thing or two about what others may need in a time of despair. John is also a believer that listening can be the greatest help that you could give someone, especially someone contemplating suicide.
One of the most challenging questions John and I tackled was "could committing suicide be the best outcome for someone"?
To even contemplate this question, perhaps one needs to first accept the paradox, complexity and messiness of life, and more importantly consider the question from the perspective of others, not self.
The answer that I suspect most people would respond with is a resounding no. How could someone taking his or her life be anything but bad?
What if we thought about this in a different way? A way focused on better understanding other people instead of imposing our own values, and controlling them? What if the only real decision that person felt like they had control of, was the decision to take their own life? Could at least being in control of that decision be better than living a life of despair, anger, guilt, pain and/or suffering? Of course, the reality is that we could never know the answer to this question, and I suspect, nor can the other person.
The Paradox of Helping. How can we ever really know what is the best 'help' for others?
Could it be that if our agenda is for others to be free (of guilt, anger, pain and despair etc…) that we need to reject the urge (and seduction) to impose our own values, beliefs and control onto them and instead, feel comfort that others are making decisions for themselves? Of course, when we understand the paradox of helping, we recognise that this may cause pain for us in doing so.
Do we try to 'help' at all cost because the pain of not helping (e.g. suicide) is too much for us to deal with, rather than considering what is best for others? This is such a challenging situation to consider, and I suspect one that is counter intuitive for most of us. I understand this. I don't want anyone I know to die, but I do want people to be free to live and make their own decisions. The Paradox of Helping?
I can't imagine the pain, suffering and anguish that someone who is considering taking their own life may feel, I imagine there is no pain like this in living. Consider how someone who is feeling this pain may feel if they constantly sense they needed to be 'fixed'. Isn't their pain enough already?
Imagine being in a situation where you were contemplating ending your life because you felt there was just nothing else that could be done to deal with your pain. Then, in a last desperate attempt to reach out, you pick up the phone. At the end of the line is someone who is there to listen and 'meet' you. Not to fix you, just to listen. The listening may just be the 'help' you are after.
Maybe the listening doesn't fix the situation you are in. Maybe the source of your pain and suffering continue. But if you have someone who can hear your story, without judgment and opinion, maybe (and of course, it has to be maybe, as there is no certainty in life), that is enough 'help' to get you through that terrible moment of loneliness and pain?
I find these tough questions. I suspect that if I was faced with the question that John and I talked about last night just a few years ago, that my answer and my thinking, would be very different.
For those of us who love to talk and spark up a conversation, perhaps being conscious of listening more is the critical if we are to truly 'help' people.
Perhaps so to is, understanding The Paradox of Helping?
If you are in a situation where you would like someone to listen without judgment and opinion you can call Lifeline on 131144. They may not be able to 'fix' your situation, but that's probably not what you need or want, you probably just want someone who will listen to, and 'meet' you.
If you'd like to support Lifeline deliver it's vital and important services, why not join their 8 for a Mate program?
The Paradox of Helping, what does this mean for you?

Q: Getting rid of square root in this integration How do I get rid of this square root so that I can integrate it?
$$S = 2 \pi a ^2 \int_0^{\sqrt{2}} t \sqrt{4t^2 + 1}\ dt$$

A: Hint: Let $x=4t^2+1$. Then $dx=8t~dt$. Can you take it from here ? :-)

A: The substitution method is usually presented like this.
$$\require{cancel}\int_a^bu'(x)f(u(x))dx = \int_{u(a)}^{u(b)}f(u)du$$
I find that adding the intermediary steps makes the integration easier for me, so I multiply by
$$\frac{du/dx}{u'(x)}$$
Notice that the numerator and denominator are the same (i.e. the derivative of $u$ with respect to $x$), so the fraction evaluates to 1.
So lets multiply now
$$\int_a^bu'(x)f(u(x))dx=\int_{x=a}^{x=b}\frac{\cancel{u'(x)}f(u(x))\cancel{dx}\cdot\frac{du}{\cancel{dx}}}{\cancel{u'(x)}}= \int_{u(a)}^{u(b)}f(u)du$$
In addition. quite often I will express $du$ as (for example) $d(4x^2+1)$
$$\begin{array}{lll}
2\pi a^2\int_0^\sqrt{2}t\sqrt{4t^2+1}dt&=&2\pi a^2\int_0^\sqrt{2}t\sqrt{4t^2+1}dt\frac{d(4t^2+1)/dt}{d(4t^2+1)/dt}\\
&=&2\pi a^2\int_0^\sqrt{2}t\sqrt{4t^2+1}dt\frac{d(4t^2+1)/dt}{8t}\\
&=&2\pi a^2\int_0^\sqrt{2}t\sqrt{4t^2+1}\frac{d(4t^2+1)}{8t}\\
&=&2\pi a^2\int_0^\sqrt{2}\frac{t\sqrt{4t^2+1}}{8t}d(4t^2+1)\\
&=&2\pi a^2\int_0^\sqrt{2}\frac{\sqrt{4t^2+1}}{8}d(4t^2+1)\\
&=&\frac{1}{4}\pi a^2\int_0^\sqrt{2}\sqrt{4t^2+1}d(4t^2+1)\\
&=&\frac{1}{4}\pi a^2\int_1^9\sqrt{u}du\\
&=&\dots
\end{array}$$
Doing things this way keeps me focused on the problem without the need to go off to the side and calculate $du$.

ANTIOCH — A two-alarm fire hospitalized two children and ripped through a section of townhouses Tuesday afternoon, a fire official said.
Both children inhaled smoke but were expected to be OK after being taken by ambulance to an hospital, said Fire Marshal Robert Marshall of the Contra Costa County Fire Protection District. Marshall could not immediately confirm the age of either child.

The fire started around 1:30 p.m. and left all eight units in the complex of townhouses in the 2700 block of Barcelona Circle uninhabitable, Marshall said. Fire crews believe the blaze began in one of the units that runs up against nearby Buchanan Road.

Firefighters controlled the blaze by 2:15 p.m., and nobody else was injured, Marshall said. A steadily increasing wind blew as crews worked to overhaul the site and keep it from re-igniting, but Marshall said crews were fortunate that the gusts were considerably more moderate during their initial arrival.
"The wind played some role in this one," he said. "How much it played is hard to say."
