HELP PLEASE In a chemical reaction, new substances are formed. But no new matter is created. The total number of each type of atom stays the same, which is another way of saying that matter (and mass) are conserved. If the elements Fe and S are present in the beginning of your reaction, those same elements will be present in the products. Their arrangement will change, resulting in different compounds and molecules than were present in the reactants. However, you won't end up with any new element. And the total number of atoms of Fe and S will be conserved.
