Why is a chemical equation balanced?

Answer and explanation

Correct answer: To obey the law of conservation of mass

A chemical equation is balanced to obey the law of conservation of mass. In a balanced equation, the number of atoms of every element is the same on the reactant and product sides, so total mass remains unchanged. Balancing does not aim to increase products or reduce reactants. Exam tip: change only coefficients while balancing, never the subscripts in chemical formulae.
