Chemical Reactions and Conservation of Mass

Using the Activity series chart, select ALL of the reactions that will occur.

• Mn + SnBr₂ ---> MnBr₂ + Sn

• Fe + CuCl₂ ---> FeCl₂ + Cu

• 2 Na + ZnF₂ ---> 2 NaF + Zn

• Cu + 2HCl ---> CuCl₂ + H2

To demonstrate the LAW OF CONSERVATION OF MASS, a chemical reaction must be:

• BALANCED

• HAVE SAME MOLECULES ON BOTH SIDES

• HAVE THE SAME NUMBER OF METALS AND NON METALS

• HAVE THE SAME STATES OF MATTER
