Dear aspirant hope you are doing well. Seems your question is not complete or something missing from your question. To balance a chemical equation. Some method are listed below. Once all the individual elements are balanced, the total number of atoms of each element on the reactant and product side are compared once again. If there are no inequalities, the chemical equation is said to be balanced. In this example, every element now has an equal number of atoms in the reactant and product side.

Thank you
