Please help me out with this pre lab assignment.

D. Relative Scales of Reduction and Oxidation Potentials ranking of ions by ease of reduction, easiest to hardest: * comparison of ranking with ranking based on reduction potentials in Table 1: ranking of ions by ease of oxidation, easiest to hardest: * comparison of ranking with ranking based on oxidation potentials in Table 1: Table 1 Selected standard reduction potentials for half-reactions Ered, V -2.37 Reduction half-equation Mg?"(aq) + 2 e" - Mg(s) Al(aq) + 3 e Al(s) Cr2+ (aq) + 2e - Cr(s) -1.66 -0.91 -0.76 -0.44 -0.26 Zn2+ (aq) + 2 e - Zn(s) Fe2+ (aq) + 2 e - Fe(s) Ni2+ (aq) + 2 e-Ni(s) Sn(aq) + 2 e - Sn(s) Pb2+ (aq) + 2 e Pb(s) -0.14 -0.13 - 0.00 - 2 H(aq) + 2 H2(g) *e Cu2+ (aq) + 2 e - Cu(s) +0.34 +0.80 Ag+(aq) + e - Ag(s)
