Which produce would best increase the amount of heat energy that is actually gained by calorimeter b

Plz choose one of the compounds from the table and explain how you know the numbers of atoms in your formula. is it possible for two different compounds to be made from the exact same two elements? why or why not? with a limited number of elements (less than 120 are known), does this mean we also have a small number of compounds or do we have a large number of compounds in this world?

If a polyatomic ionic compound has gained two hydrogen ions, then how does its name begin?
