The Deacon process is one way to recover Cl2 on-site in industrial plants where the chlorination of hydrocarbons produces HCl. The reaction uses oxygen to oxidize HCl to chlorine, as shown.

HCl + O2 → Cl2 + H2O 

a) Balance the chemical equation.

b) If 26 g of HCl reacts with an excess of oxygen, how many grams of water would result from the Deacon process?

a) 4 HCl + O2 → 2 Cl2 + 2 H2O 

b) 6.4g
