Question

Write the balanced chemical equation for the following and identify the type of reaction

Zinc carbonate(s)$\to$ Zinc oxide(s)+ Carbon dioxide(g)

Answer 1

• $\underset{\mathrm{Zinc}\mathrm{carbonate}}{{\mathrm{ZnCO}}_3\left(\mathrm{s}\right)}\underset{\mathrm{Zinc}\mathrm{oxide}}{\stackrel{∆}{\to }\mathrm{ZnO}\left(\mathrm{s}\right)}+\underset{\mathrm{Carbon}\mathrm{dioxide}}{{\mathrm{CO}}_2\left(\mathrm{g}\right)}$
• This is a decomposition reaction.
• A decomposition reaction can be defined as a chemical reaction in which one reactant breaks down into two or more products.
