4.02 chemistry notes Law of Conservation of Mass One of the most important principles of chemistry is the law of conservation of mass. This law states that matter is neither created nor destroyed during an ordinary chemical reaction. In other words‚ all of the atoms that were present at the beginning of a reaction are present at the end of the reaction—they have just been rearranged to bond differently and form new substances. It is important that chemical equations represent this law by always
