The formation of aluminum chloride can be described by the balanced chemical equation.

2Al+3Cl2⟶2AlCl3

How many moles of Cl2 molecules are required to react with 2.77 mol Al atoms?
Ammonia gas can be prepared by the reaction

CaO(s)+2NH4Cl(s)⟶2NH3(g)+H2O(g)+CaC l2(s)

In an experiment, 28.5 g of ammonia gas, NH3 , is produced when it was predicted that 41.9 g NH3 would form.
