What is the limiting reactant If 10 moles of NH3 react with 30.0 moles of NO? 4NH3+6NO --> 5N2 + 6H20

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?
