Question

zinc oxide is heated strongly in excess of air
write a balanced chemical equation for it​

Answer 1

When zinc carbonate is heated strongly in a limited supply of air, it gives zinc oxide and carbon dioxide. `underset("Zinc carbonate")(ZnCO_(3(s)))overset("heat")to underset("Zinc oxide")(ZnO_((s)))+underset("Carbon dioxide")(CO_(2(g)))`

Answer 2

Answer:

When zinc carbonate is heated strongly in a limited supply of air, it gives zinc oxide and carbon dioxide.

ZnCO3(s)Zinc carbonate−→heatZnO(s)Zinc oxide+CO2(g)Carbon dioxide
