Lithium was fused with sulfur. The resulting salt was treated with dilute hydrochloric acid, while a gas with the smell of rotten eggs was released. This gas was burned in an excess of oxygen, while a gas with a characteristic pungent odor was released. By passing this gas into excess sodium hydroxide, a middle salt was formed. Write the equations for the described reactions.

2Li + S → Li2S
Li2S + 2HCl → 2LiCl + H2S↓
2H2S + 3O2 → 2SO2 + 2H2O
SO2 + 2NaOH → Na2SO3 + H2O
