Question 1

The reaction below occurs in basic solution. In the balanced equation, what is the sum of the coefficients?
              Zn + NO3–→ Zn(OH)42– + NH3

◦ 12
◦ 15
◦ 19
◦ 23
◦ 27

Question 2

The reduction potentials for Au3+ and Ni2+ are as follows:
Au3+ + 3e–→ Au, E° = +1.50 V
Ni2+ + 2e–→ Ni, E° = –0.227 V

Calculate ΔG° (at 25°C) for the reaction:
2Au3+ + 2Ni → 3Ni2+ + 2Au
