19.04 g of ammonia gas was mixed with 31.10 g of hydrogen chloride gas in an enclosed container. Calculate:
a) Which of the reactants were in excess and how much,
b) How much of ammonium chloride was formed,
c) How much more extra of the insufficient reactant would be needed to completely react with the excess remaining of the other reactant? (N = 14, H = 1, Cl = 35.5)
