What is the equation for the oxidation and reduction for this equation, please?

Question

KMnO4(aq) + H2SO4(aq) + H2O2 (aq) --> ?

Answer 1

To answer your question, I have to get the following Standard Reduction Potentials:

MnO4- + 4 H+ + 3 e- ==> MnO2(s) + 2 H2O, E° = +1.70 . . . (1)

O2(g) + 2 H+ + 2 e- ==> H2O2(aq), E° = +0.70V . . . . . . . . .(2)

2(1)-3(2):

2MnO4- + 2 H+ + 3H2O2(aq) ==> 2MnO2(s) + 3O2 + 4 H2O, E° = +1.00V

Adding K2SO4 to both sides, we have:

2KMnO4 + H2SO4 + 3H2O2(aq) ==> 2MnO2(s) + 3O2 + K2SO4 + 4 H2O
