Question

What is a balanced chemical equation? Why should chemical equations be balanced?

Answer 1

Balanced chemical equation

• A balanced chemical equation is an equation where the number of atoms of each type in the reaction is the same on both reactants and product sides.
• The mass, as well as the change, are equal in a balanced chemical equation.

Law of conservation of mass

• The law of conservation of mass is the governing law for balancing a chemical equation.
• The law states that ‘mass can neither be created nor be destroyed in a chemical reaction’.
• Due to this reason, chemical equations must be properly balanced.
