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.
