A chemical equation is balanced according to the law of ___________.
Balanced Chemical Equation:
(1) An equation having an equal number of atoms of each element on the reactant and product side is called a balanced chemical equation.
(2) A chemical equation is balanced according to the law of conservation of mass which means that the mass of reactant and product are equal.
(3) Law of conservation of mass states that “mass can neither be created nor destroyed”.
Therefore, a chemical equation is balanced according to the law of conservation of mass.
