2H2O2 --- 2H2O + O2 is this a redox reaction if so what is the oxidized reactant and reduced reactant

Answer 1

Yes it is a redox equation.
O goes from -1 for each atom on the left to zero on the right(with O2). It goes from -1 on the left to -2 on the right (with H2O).
Oxidation is the loss of electrons. Reduction is the gain of electrons.
