For the same reason as a mathematical equation. The word equation is derived from EQUAL - so to be equal or balanced there has to be the same number of atoms on each side.
Atoms
A properly written chemical equation will always show the same number of atoms of each elemental on each side, showing that no atoms are created or destroyed in the chemical reaction.
The coefficient times the subscripts in a chemical formula show you the number of atoms of each element for each substance in the equation.
It is important to know the relative number of atoms of each element in a compound for the chemical composition.
Rules of balancing chemical equations:1. write the unbalanced equation2. count the number of atoms of the same element on reactant and product side of equation3. make the number of atoms the same by changing the coefficients, not subscripts4. balance hydrogen and oxygen last5. reduce coefficients if possibleThe first step in balancing a chemical equation is identifying all elements.For example:H2OSo the elements you would identify are H (hydrogen) and O (oxygen).--------------------------------------------------------------------------------------------------------b. identify the reactants and products. - (e2020)

this is called having a balanced equation .....if both sides are not balanced u must correct it by changing the number of moles

All properly balanced chemical equations fit that criteria: they must have the same number of atoms of each element on each side of the "yield" arrow. Balancing an equation can be achieved by using whole number coefficients as needed. This upholds the Law of Conservation of Mass, which states that matter cannot be created or destroyed.
Chemical equations usually do not come already balanced. A balanced equation has equal numbers of each type of atom on each side of the equation.A chemical equation is balanced by balancing the number of atoms on products and reactants side.

That the number of atoms on the left side of the equation must be the same number of atoms that are on the right side of the equation.
