Question
Explain the following reaction with the balanced equation.
Zinc carbonate is heated strongly in limited supply of air
Advertisements
Solution
Zinc carbonate is heated strongly in a limited supply of air to convert it to zinc oxide. This process is called calcination.
\[\ce{\underset{\text{Zinc carbonate}}{ZnCO_{3(s)}} ->[Heat] \underset{\text{Zinc oxide}}{ZnO_{(s)}} + \underset{\text{Carbon dioxide}}{CO_2↑}}\]
