Question: Balance these equations for redox reactions occurring in basic solution. (a) CrO 4 2- + S 2 O 4 2- Cr(OH) 3 (s) +

Balance these equations for redox reactions occurring in basic solution.

(a) CrO42- + S2O42- → Cr(OH)3(s) + SO32-

(b) [Fe(CN)6]3- + N2H4 → [Fe(CN)6]4- + N2(g)

(c) Fe(OH)2(s) + O2(g) → Fe(OH)3(s)

(d) CH3CH2OH + MnO4- → CH3COO- + MnO2(s).
