The law of conservation of matter states that matter can be neither created nor destroyed during a chemical reaction. This means that all the atoms present before a reaction must be present after the reaction, and that the total mass of a system does not change as the result of a chemical reaction.he law of conservation of matter states that matter can be neither created nor destroyed during a chemical reaction.

For sustainable energy resources, see Energy conservation. In physics, the law of conservation of energy states that the total energy of an isolated system remains constantâit is said to be conserved over time. Energy can neither be created nor destroyed; rather, it transforms from one form to another. For instance, chemical energy can be converted to kinetic energy in the explosion of a stick of dynamite. A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind cannot exist.
