Conservation of Mass and Chemical Equations

Conservation of Mass and Chemical Equations. section 4.3. Law of Conservation of Mass. In a chemical reaction, the atoms that make up the starting material(s) undergo a rearrangement to form the product(s). Since no atoms are lost of gained in a chemical reaction, mass is conserved.
