Question

Give one example for the thermal decomposition of a carbonate.

Answer 1

Thermal decomposition reaction:

The decomposition reaction carried out in the presence of heat or temperature is called a thermal decomposition reaction. The reactant tends to break down in presence of high temperatures.

Example of thermal decomposition of a carbonate:

One example of a thermal decomposition reaction of a carbonate is given below.
Copper carbonate $\left({\mathrm{CuCO}}_3\right)$is a carbonate compound that can undergo thermal decomposition to give two new compounds. They are Copper oxide $\left(\mathrm{CuO}\right)$ and Carbon dioxide $\left({\mathrm{CO}}_2\right)$. The single compound is broken down into two new compounds in the case of a decomposition reaction.
$$\begin{gathered} {\mathrm{CuCO}}_3+\mathrm{heat}\to \mathrm{CuO}+{\mathrm{CO}}_2 \\ (\mathrm{Copper}\left(\mathrm{Copper}\mathrm{oxide}\right)\left(\mathrm{Carbon}\mathrm{dioxide}\right) \\ \mathrm{carbonate}) \end{gathered}$$
