Use the following steps to balance the redox reaction below: Na + Cu2+ → Na+ + Cu

a. Write the oxidation and reduction half-reactions. Make sure each half-reaction is balanced for number of
atoms and charge. (3 points)

b. Multiply each half-reaction by the correct number, in order to balance charges for the two half-reactions. (1
point)

c. Add the equations and simplify to get a balanced equation (1 point)
