Question 1

What is the balanced chemical equation for the galvanic cell reaction expressed using shorthand notation below?

Al(s) ∣ Al3+(aq) ∣∣ Fe2+(aq) ∣ Fe(s)

◦ 3Al(s) + 2Fe2+(aq) → 3Al3+(aq) + 2Fe(s)
◦ 3Fe(s) + 2Al3+(aq) → 3Fe2+(aq) + 2Al(s)
◦ 2Al(s) + 3Fe2+(aq) → 2Al3+(aq) + 3Fe(s)
◦ 2Fe(s) + 3Al3+(aq) → 2Fe2+(aq) + 3Al(s)

Question 2

What is the balanced equation for the galvanic cell reaction expressed using shorthand notation below?

Ni(s) ∣ Ni2+(aq) ∣∣ Cl2(g) ∣ Cl-(aq) ∣ C(s)

◦ Ni(s) + Cl2(g) → Ni2+(aq) + 2Cl-(aq)
◦ Ni2+(aq) + 2Cl-(aq) → Ni(s) + Cl2(g)
◦ Ni2+(aq) + 2Cl-(aq) → NiCl2(s)
◦ Ni(s) + 2Cl-(aq) → Ni2+(aq) + Cl2(g)

Answer 1

2Al(s) + 3Fe2+(aq) → 2Al3+(aq) + 3Fe(s)

Answer 2

Ni(s) + Cl2(g) → Ni2+(aq) + 2Cl-(aq)
