Redox and Half Reactions HELP!?

Question

Oxidation: 2H(2)O(2) --- 2 O(2) + 4H(+) + 4e-
Reduction: Fe (3+) + e- ---- Fe (2+)

Combine the two half reactions to obtain a balanced overall redox reaction.

**(All () numbers or symbols are () to show they are sub numbers and symbols)

If anyone has any suggestions I would really appreciate it! Thank you

Answer 1

Halve the first equation, double the second and add them together:

H2O2 + 2Fe3+ -----> O2 + 2H+ + 2Fe2+
