### Same charge

Sometimes when I write half reactions both species have the same charge? What do I do, how do I know how many electrons have been transferred?

### Re: Same charge

First, make sure you balance the charges of each half reaction (for the most part you should need electrons to balance the half rxns). If then, you notice that both half rxns have the same charges then you should be fine as the electrons eventually cancel out.
