in a particular redox reaction, MnO2 is oxidized to MnO4– and fe3+ is reduced to fe2+. Complete and balance the equation for this reaction in acidic solution. Phases are optional.
Instead of me guessing what you know (or don't know) about this why don't you tell me exactly what your problem is in redox equations and let me help you through it?
I keep getting
but it is saying incorrect
MnO2 + 2H2O + 3Fe3+ -> 3Fe2+ + MnO4- + 4H+
