Question

ammonia, NH3, is a typical ingrediant in household cleaners. it is produced through a combination reaction involcing N2(g) and H2(g). if 12.0 mol of H2(g) react with excess N2(g), how many moles of ammonia are produced?
1/2N2+3/2H2 => NH3 or
1/3N2+H2 => 2/3NH3

so 12*2/3 = 8 moles HN3
8 mols is correct but it produces NH3 and not HN3.
