Question

What happens when zinc carbonate is heated? (write balanced chemical equation)

Answer 1

1. Decomposition reaction:

The compounds undergo decomposition reaction in presence of heat or electricity. A decomposition reaction is one of the types of chemical reaction.

2. Reaction of zinc carbonate upon heating:
The compound named Zinc carbonate undergoes decomposition in the presence of heat to form Zinc oxide and Carbon dioxide. This is also called a thermal decomposition reaction.

The equation has a similar count of atoms on both sides. The balanced chemical equation for the reaction is given below.

$$\begin{gathered} {\mathrm{ZnCO}}_3\left(\mathrm{s}\right)\stackrel{\mathrm{Heat}}{\to }\mathrm{ZnO}\left(\mathrm{s}\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right) \\ (\mathrm{Zinc}\mathrm{carbonate})(\mathrm{Zinc}\mathrm{oxide})(\mathrm{Carbon}\mathrm{dioxide}) \end{gathered}$$
