in 4 hours, i will be reporting on this..so please help me.. explain comprehensively if possible..THANKS>..
when you combine, postassium permanganate (KMnO4), Sulfuric acid ( H2SO4), water (H2O), and hrydrogen peroxide (H2O2), what peoduct will it yield? thanks!!!

MnO2 does not form in acidic solution.
Hydrogen peroxide is oxidised to oxygen gas and water, and the purple (MnO4)- ion is reduced to colourless Mn2+.
2(MnO4)- + 5H2O2 + 6H+ -------> 5O2 + 2Mn2+ + 8H2O

Oxygen, I think.
The entire equation ought to be:
H2SO4 + 2KMnO4 + H2O2 -> 2MnO2 + 2H2O + 2O2 + K2SO4
The permanginate is reduced to manganese oxide and the peroxide is oxidized to oxygen gas and water. The sulfuric acid supplies hydrogen ions and forms Potassium sulfate. A dark purple solution becomes clear with a dark brown precipitate on the bottom and the evolution of oxygen bubbles.
