Reference no: EM132543066

Heating together the solids NH4Cl and Ca(OH)2 can generate ammonia. Aqueous CaCl2 and liquid H2O are also formed.

2NH4Cl + Ca(OH)2 → 2 NH3 + CaCl2 + H2O

a) If a mixture of 33.0 g each of NH4Cl and Ca(OH)2 is heated, how many grams of NH3 will form?

b) How many formula units of CaCl2 are produced?
