What is law of conservation

Answer» The law of conservation of energy states that energy can neither be created nor be destroyed. It may be transferred from one of its forms to the other. If you take all forms of energy into account, the total energy of an isolated system always remains constant.Law of conservation of mass: It states that mass can neither be created nor destroyed in a chemical reaction. During any change, physical or chemical, matter is neither created nor destroyed. However it may change from one form to another.
According to the law the total mass of product must be equal to the total mass of reactantOrthe number of atoms of each element of the reactant must be equal to the number of atom of each element of product
