Question

Identify the following reaction.

${\mathrm{ZnCO}}_3\to \mathrm{ZnO}+{\mathrm{CO}}_2$

Answer 1

Definition of decomposition reaction.

The reaction in which a complex compound is breakdown into simpler one is called decomposition reaction.

• ${\mathrm{ZnCO}}_3\left(\mathrm{s}\right)\to \mathrm{ZnO}\left(\mathrm{s}\right)+{\mathrm{CO}}_2\left(\mathrm{g}\right)$
• This is an example for decomposition reaction.
• Here Zinc carbonate is split up into Zinc oxide and Carbon dioxide.
