In chemical reaction, atoms
always are rearranged. They are never destroyed or created because it would
contradict the law of conservation of energy. The law of conservation of energy
states that a matter cannot be created nor destroyed. It can only be formed in
one way or the other. Also it cannot be neutralized. Resulting in one cannot be
part of a chemical reaction. An example of this is the reaction HCl + NaOH
-> NaCl + H2O. the reactants and products are not created, they are just
formed into another substance.
