Question

What is the balanced chemical equation? Why should chemical equation be balanced ?​

Answer 1

If in a chemical equation the total number of atoms in the reactant side are equal to the total number of atoms in the product side then the chemical reaction is said to be balanced. For example The chemical reaction should be balanced show that it can follow the law of conservation of mass.

Answer 2

Explanation:

A chemical equation in which the total number of atoms in reactants and total number of atoms in product are equal is known as balanced chemical equation.

For example-:

normal equation,

Mg + O2 ------> MgO

balanced equation,

2Mg + O2 --------> 2MgO

in the above example we can see that the atoms of Mg (Magnesium) and O (Oxygen) are equal in both sides.

Chemical equation should be balanced to satisfy the law of conservation of mass which states that the mass of products in a chemical equation must equals the mass of reactants.
