Question

Give one example of a decomposition reaction which carried out

by applying heat

Answer 1

Decomposition Reaction:

A reaction in which a single substance splits into two or more simple substances under suitable conditions.

$\mathrm{AB}\to \mathrm{A}+\mathrm{B}$

Example of decomposition reaction carried out by applying heat:

When a decomposition reaction is carried out by heating, it is called thermal decomposition. When copper carbonate (CuCO₃) is heated it breaks down to form copper oxide (CuO) and carbon dioxide (CO₂).

${\mathrm{CuCO}}_3\stackrel{∆}{\left(\mathrm{s}\right)\to }\mathrm{CuO}\left(\mathrm{s}\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right)$.

Thus, thermal decomposition is an example of a decomposition reaction by applying heat.
