Question

classify each of the following as a combination, decomposition, single displacement, double displacement, or combustion reaction.

1. niso₃(s) → nio(s) + so₂(g)

Explanation:

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler substances. In the given reaction \(NiSO_{3}(s)\to NiO(s) + SO_{2}(g)\), one compound (\(NiSO_{3}\)) is splitting into two simpler substances (\(NiO\) and \(SO_{2}\)). This matches the definition of a decomposition reaction.

Answer:

Decomposition reaction.
