  1. Law of Conservation of Mass

    In a chemical reaction, original substances (reactants) are consumed and new substances (products) are formed. The total mass of the reactants will always equal the total mass of the products. Reactants Products
  2. The law of conservation of mass states that in any physical change of chemical reaction, mass is neither created nor destroyed; it is conserved. The amount of mass of the reactants must equal the amount of mass found in the products! NH4NO3 N2 + O2 + H2O 40g  14g+ 8g +___ MgCl2 + Ca(OH)2 Mg(OH)2 + CaCl2 32g + ___ 25g +28g
