. When aqueous sodium sulfite reacts with aqueous hydrochloric acid, sulfur dioxide gas is produced.

a) Write a balanced chemical equation for this reaction. 

b) Write a net ionic equation for this reaction.

c) 100.0 mL of 0.200 M sodium sulfite is mixed with 100.0 mL of 0.200 M hydrochloric acid, and the sulfur dioxide is collected over water at a total pressure of 1.00 atm and a temperature of 25°C. If 223 mL of gas is collected, what is the percent yield for the reaction?
