Question

What is decomposition reaction? Explain with suitable reaction.

Answer 1

A decomposition reaction occurs when one reactant breaks down into two or more products.

This can be represented by the general equation:

AB → A + B.

Example.
$CuC{O}_{3\left(s\right)}\to Cu{O}_{\left(S\right)}+C{O}_{2\left(g\right)}$
