Question

Differentiate between the following

Balanced and unbalanced chemical reactions.

Answer 1

S.No.	Balanced chemical reaction	Unbalanced chemical reaction
1	The chemical equation in which the number of atoms of each element on the reactant side as well as the product side is equal are known as a balanced equation.	The chemical equation in which the number of atoms of each element on the reactant side as well as the product side is not equal is known as an unbalanced equation.
2	The sum of masses of reactant is equal to sum of masses of product. Thus it follows the law of mass conservation	The sum of masses of reactant is not equal to the sum of masses of product. Thus it does not follows the law of mass conservation
3	$2{\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to 2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$ this is a balanced equation as the number of atoms of reactant and product side are equal.	${\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\to {\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$this is an unbalanced equation as the number of atoms of reactant and product side are not equal.
