a. Use the following steps to balance the redox reaction below. Al(s) Ni2 (aq) Ni(s) Al3 (aq)

i. Write the oxidation and reduction half-reactions. Make sure each half-reaction is balanced for number of atoms and charge.
ii. Multiply each half-reaction by the correct number in order to balance charges for the two half-reactions.
iii. Add the equations and simplify to get a balanced equation.
