I need help determining how to set up a half reaction. If there's already a thread explaining this, please point me to it. I'm new to the forum so I'm not sure where things should be.

H2O2 + MnO4- + H+
Mn2+ + H2O + O2
First recognise what's being oxidised and reduced:
What oxidation state is Mn in MnO4 and Mn2+?
What oxidation state is O in H2O2? And O2?
