Question

How do you write and balance the chemical equation that relates to this word equation: Solid zinc carbonate is heated and broken down into solid zinc oxide and carbon dioxide gas?

Answer 1

Zinc Carbonate: ZnCO3

Zinc Oxide: ZnO

Carbon Dioxide: CO2

UNBALANCED EQUATION:

ZnCO3---------> ZnO+ CO2 (Heat should be written above the arrow)

BALANCED EQUATION:

ZnCO3---------> ZnO+ CO2 (Heat should be written above the arrow)

As the no. of zinc, oxygen and carbon atoms are equal on both the sides and hence the equation is already balanced.
