Question 4: Balancing Redox Equations (5 points) Use the following steps to balance the redox reaction below:
Mg + Aut → Mg2+ + Au
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)
