The Law of Conservation of Mass states that during a chemical reaction, mass/matter is not Because of this law, there must be exactly Jon each side of a chemical equation. To check if an equation is balanced or not, simply count the number of atoms of each element on the reactant side of the equation and check to see if there are the same number of atoms of each or the same number and kind of element on the side of the equation. If so, it is balanced.
