33. The legendary Captain Nemo - made famous by the French author Jules Verne in his book 20000Leagues Under The Sea – may have powered his submarine, the Nautilus, using a battery made up of theZn2+/Zn and the Cr20,2-/Cr3+ half-cells. The relevant half-reactions are shown in bold:Au3+(aq) + 3eAu(s)+1.50 VCl2(g) + 2e2C11-(aq)+1.36 VCro,?-(aq) + 14 H1*(аq) + 6е2 Cr3+(aq) + 7 H2O(e)+1.23 VCu2+(aq) + 2eCu(s)+0.34 V2H20(l) + 2eН2(g) + 20H1- (aд)0.00 VZn2+(aq) + 2eZn(s)-0.76 V=Na1+(aq) + 1eNa(s)-2.71 V33а.Electrons flow from the Cr20,2-/Cr3+ half-cell to the Zn2+/Zn half-cell.TF33b. The reducing agent is Zn(s) and the oxidizing agent is Cr20,2-(aq).TF33c. The Zn2+/Zn half-cell is the cathode.TF33d.Cations move through the salt bridge toward the Zn2+/Zn half-cell.TF33e. This battery will produce close to 1.72 volts of electrical energy.TF33f. Cu(s) can be used as the electrode in the Cr20,2-/Cr3+ half-cell.TF33g.Zn(s) electrode shouldwith water.F33h. Cl2 is a stronger oxidizing agent than Cr20,7-.TF33i. Magnesium, Mg, is a more reactive metal than Zn. Substituting the Mg2+/Mg half-cellfor the Zn2+/Zn half-cell will result in a battery that produces a smaller voltage.TF
