Redox reaction?

can you help me on this acidic equation?

S406 (2-) +Al -------> H2s + Al (3+)


and



MnO4(-) + C2O4 (2-) -----> Mn (2+) + CO2

Answer:
S4O6(2-) + 12H+ + 18e- >> 4S 2- + 6H2O

(Al >> Al3+ + 3e-) x 6
______________________________...

6Al + S4O62- + 12H+ >> 4S2- + 6H2O


(MnO4- + 8H+ + 5e->> Mn2+ + 4H2O) x2

(C2O42- >> 2CO2 + 2e-) x5
______________________________...

2MnO4- + 16H+ + 5C2O42- >> 2Mn2+ + 10CO2 + 8H2O
mmm, Please detail what you want. Obviously reactions are incomplete but it is not clear if you just want to complete the missing species, balance it, the complementing half-cell reaction, calculate the equilibrium constant, pK or what.
