Using the set of smallest possible integer coefficients to balance the redox equation
H2O2 +MnO−4 > O2 +Mn+2
(acidic solution), the coefficient for H2O2 is
1. 5.
2. The correct coefficient is not given.
3. 2.
4. 7.
5. 4.

You need to learn how to do these instead of us giving you the answers. What is your big hang up on these problems.
