The conservation of mass law states that mass can not be created or destroyed. Lets apply this to a chemical equation. If you mix two elements and they react and form something new, you need to have the SAME amount of "stuff" on both sides or somewhere along the line mass either disappeared or sprouted into existence, which would violate that law. We balance equations so the same amount of atoms appear on both sides, thus following the law.

when you balance an equation you make sure that the amount of stuff that you put in is = the amount of products .

 the law of mass conservation is as states :that mass cannot be created or destroyed , so when you balance an equation you are following this law

Mass can neither be created or destroyed therefore the mass of the reactants must equal the mass of the products
