Question

we need a balance chemical equation give reason to justify the statement ​

Answer 1

we needed generally our balance chemical equation because is equations follow the law of conservation of mass the number of atoms in the reactant and the products side is equal and it is more informative way to write the chemical equation. hope this may help you

Answer 2

Answer:

Balanced chemical equation:-

A chemical equation in which the number of atoms of reactants are equal to the number of atoms of products is called a Balanced chemical equation.

The chemical equation needs to be balanced so that it follows the law of conservation of mass.

We need to balance a Chemical equation because of following reasons :-

1. According to the law of conservation of mass, mass (or atoms) are neither created nor destroyed in chemical reactions.
2. It means the total mass of the products formed in chemical reaction must be equal to the mass of reactants consumed.
