Liquid water and sulfur dioxide gas are formed by the decomposition of aqueous sulfurous acid h2so3. write a balanced chemical equation for this reaction.

When an aqueous solution of sulfurous acid (H2SO3) decomposes, it would form two products which are water and sulfur dioxide. The balanced chemical reaction would be written as follows:

H2SO3 = H2O + SO2

This reaction is reversible so that the products of the decomposition can react and produce again the sulfurous acid.
