Answer:

CaCO₃(s) → CaO(s)+CO₂(g)

Explanation:

We are required to balance the equation given;

We need to ask ourselves some questions;

What is a balanced equation?

  • A balanced equation is an equation that has equal number of atom of each element on both sides of the equation.

How do we balance chemical equations?

  • Chemical equations are balanced by putting appropriate coefficients on the reactants and products in the equation.

Why is it important to balance chemical equations?

  • Chemical equations are balanced to ensure they obey the law of conservation of mass.
  • According to the law of conservation of mass, the mass of the reactants should be equal to the mass of the products.

In this case;

The equation given is;

CaCO₃(s) → CaO(s)+CO₂(g)

  • The equation is balanced since the number of atoms of each element is equal on both sides of the equation.
  • That is, 1 calcium atom, 1 carbon atom and 3 oxygen atom on both sides of the equation.
