Hey there!
We balance chemical equations because of the law of conservation of mass.
The law of conservation of mass states that matter cannot be created or destroyed, so we must have the same amount of each element on each side of a chemical equation.
The products of a chemical reaction must be equal to the reactants to follow the law of conservation of mass.
Hope this helps!
