Hi, the picture with the chart is the battery referred to. Thank you so much. 34. Which of the following is the correct equation for the reaction that occurs in this battery?A. Zn(s) + Cr20,2-(aq) + 14 H1+(aq) → Zn²*(aq) + 2 Cr3*(aq) + 7 H2O(t)B. 3 Zn(s) +Cr20,2-(aq) + 14 H1+(aq) → 3 Zn2+(aq) + 2 Cr3+(aq) + 7 H2O(t)C. 3 Zn2+(aq) + 2 Cr3+ (aq) + 7 H2O(t) → 3 Zn(s) + Cr2077¯(aq) + 14 H1+(aq)D. 3 Zn(s) + 2 Cr3+(aq) + 7 H20(e) → 3 Zn²+(aq) + Cr2O,2-(aq) + 14 H1+(aq) 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) + ЗеAu(s)+1.50 VCl2(g) + 2e2C11-(aq)+1.36 VCroz2-(ag) + 14 H1*(аq) + 6е2 Cr3+(aq) + 7 H2O(l)+1.23 V=Cu2+(aq) + 2eCu(s)+0.34 V2H20(l) + 2eН2(8) + 20H1-(aq)0.00 VZn2+(aq) + 2eZn(s)-0.76 V=Na1+(aq) + 1eNa(s)-2.71 V
