B. VOLTAIC CELL then i wery moral is mg Cell Voltage, mV Mg - Cu +6.78 1678 Mg - Za 650 27 1. Write the half-cell reactions and calculate the standard cell potential, for the Mg-Cu voltaic cell. Oxidation half-cell Reduction half-cell Cu2+ + 2e Cu E = +0.340U to = -2.356 V Чg ? Mg 2 +2e 27 Complete equation Standard cell potential, E, Mg + Cu2+ Mg 2+ + Cu — + + 2.7097 to cell = +2.372+0.337=/+ 2.709 /

2. Write the half-cell reactions and calculate the standard cell potential, E for the Mg-Zn voltaic cell. E- Oxidation half-cell an + ze 7 in Reduction half-cell to = -0.76 V Mg, 7 Mg 2+ the — 2.356 V 2- Zn? + Complete equation Standard cell potential, E Mg → Zn + Mg 2+ 1.596 V - 2.3 56v - (-0.760) = -1.5960 Tell
