Question 1

For a galvanic cell that uses the following two half-reactions,

Cr2O72-(aq) + 14 H+(aq) + 6 e- → 2 Cr3+(aq) + 7 H2O(l)

Pb(s) → Pb2+(aq) + 2 e-


how many moles of Pb(s) are oxidized by one mole of Cr2O72-?
◦ 6
◦ 3
◦ 2
◦ 1

Question 2

What is the shorthand notation that represents the following galvanic cell reaction?

Fe(s) + Cu(NO3)2(aq) → Fe(NO3)2(aq) + Cu(s)


◦ Cu(s) ∣ Cu2+(aq) ∣∣ Fe2+(aq) ∣ Fe(s)
◦ Fe(s) ∣ NO3-(aq) ∣∣ NO3-(aq) ∣ Cu(s)
◦ Cu(s) ∣ Cu(NO3)2(aq) ∣∣ Fe(NO3)2(aq) ∣ Fe(s)
◦ Fe(s) ∣ Fe2+(aq) ∣∣ Cu2+(aq) ∣ Cu(s)
