Does O2 oxidates or reduces in 2H2O2 equals 2H2O plus O2?

2H2O2 <-> H2O + O2 the oxidation number of each O in H2O2 is -1 the oxidation number in H2O is -2 the oxidation number in O2 is zero. The average oxidation number of oxygen atoms on both sides of the equation. is the same. So overall the net change to oxygen is zero one is reduced two are oxidised. Looked at from the viewpoint of the oxygen atoms in O2 they started off with oxidation number of -1 and have ended up with 0, so they have been oxidised. (oxidation is loss of electrons, and therefore an increase in oxidation number.)

When the H2O2 serves as an oxidizing agent which product might be formed from it O2 or H2O?

When H2O2 acts as an oxidizing agent, the H2O2 must be reduced. Therefore, the product from it will be water, in which oxygen has an oxidation number of -2, whereas in H2O2 has an oxidation number of -1 and in O2 the oxygen has an oxidation number of 0.
