Chemical reactions never result in the loss or gain of mass. This is due to the fact that during chemical reactions, no atoms are generated or destroyed. Matter is not created nor destroyed in routine laboratory operations, and elements are not changed into other elements. Because no matter is generated or destroyed during a chemical reaction, the total mass of reactants and products is the same.Even though atoms interact and form new products in a chemical reaction, mass is conserved. To generate the products, the atoms from the reactants separate, rearrange, and re-bond in a new order. The mass of the system has not changed because no new atoms have entered or left it.
