Problem- Balance the following half reactions by adding the appropriate number of electrons. Which are oxidation half- reactions and which are reduction half-reactions? If you could show all steps it would be appreciated!

A.) 8H2S(g) ---> S8(s) +16 H+(aq)

B.) I2(s) +6H2O (l) ---> 2IO-3 (aq) + 12H+ (aq)

C.) VO+2 (aq) +2H+ (aq) ---> VO2+ (aq) + H2O (l)

Provide me complete explanations of above question so I can get high score
