Question

This reaction is an example of what type of reaction? H2SO3(aq) H2O(l) + SO2(g)

a. a synthesis reaction
b. a disynthesis reaction
c. a combustion reaction
d. a decomposition reaction

Answer 1

Answer: Option (d) is the correct answer.

Step-by-step 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.

Answer 2

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.
