Principle of conservation of mass


Pricnipio that establishes that the mass of the reactants is equal to the mass of the products of the reaction. It is an experimental law that was announced by Lavoiser in 1789 and that served to abandon the theory of phlogiston. The law of conservation of mass is not fulfilled in nuclear reactions, since in them there is variation of mass that is transformed into energy. to be exact we should talk about the principle of conservation of mass-energy.
