How do we represent the oxidation of #Cr^(3+)# ion to #CrO_4^(2-)# by hydrogen peroxide, using the method of half-equations?
By the method of half-equations............
Is this balanced with respect to mass and charge? It is your problem not mine.
Again is the thing balanced?
To give the overall redox equation, we cross-multiply the individual redox equations:
And then we SUBTRACT the superfluous reagents from each side:
But you wanted the reaction done under basic conditions. And so we add
