Balancing Equation using redox reactions?

[r_swayze]

OF₂ --> F^- + O₂ + H₂O

OF₂ --> F^-

2H⁺ +OF₂ --> 2F^- + H²O

2H⁺ +OF₂ + 4e^- --> 2F^- + H²O

This is as far as I can get. I don't know how to do the other half of the redox since the equation would be:

OF₂ --> O² + H₂O

What do I do here? Maybe I am not setting this up correctly?

Please elaborate a little bit.

Are you expected to use oxidation numbers or half reactions?

Anything about conditions - low pH, high pH, just hydrolysis in water?

The problem states:

"Balance the following redox reaction:

In basic solution, oxygen difluoride reacts to produce fluoride ion, oxygen, and water."

I figured out one way of doing it by just adding H2O, H^+ ions, and OH^- ions to either side and balancing it, but I want to know how to do it using half reactions.

Assume OH^- is being oxidized to O₂ and water.
