An example of a polyatomic ion is the hydroxide ion; consisting of one oxygen atom and one hydrogen atom, hydroxide has a charge of â1. Its chemical formula is O H â . An ammonium ion is made up of one nitrogen atom and four hydrogen atoms: it has a charge of +1, and its chemical formula is N H 4 + .Polyatomic ions are often useful in the context of acid-base chemistry or in the formation of salts.A polyatomic ion can often be considered as the conjugate acid/base of a neutral molecule. For example, the conjugate base of sulfuric acid (H 2 SO 4) is the polyatomic hydrogen sulfate anion (HSO 4 â).ts chemical formula is O H â . An ammonium ion is made up of one nitrogen atom and four hydrogen atoms: it has a charge of +1, and its chemical formula is N H 4 + . Polyatomic ions are often useful in the context of acid-base chemistry or in the formation of salts.
Cruises with Carnival Cruise Lines are mostly all-inclusive, which means the majority of the expenses incurred for a Carnival cruise vacation are included in the price. Cruise expenses can include accommodations, dining, entertainment, activities and youth programs.
I calculated the additional cost for the inside room to only be about $400 more for a 7-night cruise on Carnival. I don't know any parent would not pay $400 ($57/night) to have a private stateroom without the kids sharing a 185-square-foot cabin. âScott from Plainview, NY.
