I was told we should know that Br2, and Hg are liquid, H2, N2, O2, F2, I2, and Cl2 are gases and their standard enthalpy of formation is 0. Besides the ones I named, any other ones should be given to us.

On Friday Lavelle went over three methods. If I understood right, he provided examples for the the 2nd and 3rd, but I am not sure how to use the first. Can someone explain how or when we'd use standard reaction enthalpy?

I have a hard time identifying what is what in wordy questions. For instance I often mix up what is the Molarity, number of moles of solute, or the volume. And I have a hard time with excluding unnecessary givens in the equation. Does anyone have any advice? Molarity is moles/Liters and is sometime...

I am having trouble understanding the how something is a lewis base/acid. I know that a Lewis base is an electron pair donor and a Lewis acid accepts an electron pair. How do they "donate" or "accept" electrons?

In lecture, the first example Lavelle went over for finding K was about a reaction that had gases but he went on to explain partial pressure. My question is, when asked for equilibrium for a reaction of gases is it in partial pressure or does it depend on what is being asked?

For a) the alphabetical letter for l=1 is p. Also the quantum/group number is given (4) So it is 4p. The most # of electrons 4p can have is six. For c, the group number is given 2. The most number of electrons that group 2 can have is 8. (2s2 4p6) 2+6=8 I am not sure how to find the others because i...

I have a question regarding the response to the question. Are velocity and the light constant the same? Because I know that c= wavelength x frequency. I did not know that wavelength x frequency=velocity?

In the Limiting Reactants module, Dr Lavelle mentioned how to get to the theoretical yield but there was no example on how to. I am not quite sure how to find it. If someone could show me with an example I would greatly appreciate it. Thanks!
