This reaction H2SO3(aq) H2O(l) + SO2(g) is an example of what a decomposition reaction. It is not a replacement reaction because no other
compound is involved. It is not a combustion reaction because no oxygen is
involved.

Answer: Option (d) is the correct answer.

Explanation:

A chemical reaction in which a compound dissociates to give two different compounds or atoms is known as a dissociation reaction.

For example, \(H_{2}SO_{3}(aq) \rightarrow H_{2}O(l) + SO_{2}(g)\)

Here, sulfurous acid dissociates into water and sulfur dioxide gas. Both water and sulphur dioxide have different properties than sulfurous acid.

Therefore, we can conclude that the given reaction is an example of a decomposition reaction.
