Why do chemists balance chemical equations?

Chemists balance chemical equations to reflect the law of conservation of mass: matter cannot be created or destroyed in a chemical reaction. This means the same number of atoms of each element must be on both sides of the equation. Coefficients are adjusted to give the smallest whole-number ratios that make those atom counts equal, since each coefficient multiplies the amount of substance involved. This foundation of stoichiometry lets us predict how much product will form from given reactants and plan reactions accurately. Other ideas, like maximizing yield or aesthetics of coefficients, don’t capture this fundamental necessity.
