Half reactions

Postby 005199302 » Tue Feb 26, 2019 9:52 pm

If a question asks for the balanced half reactions, is the final answer with or without multiplying the half reaction through by a number (in the case that you need to match the electrons transferred in both half reactions)?

Without multiplying. When it asks for the balanced half reaction, you just have to provide the balanced half reaction with the lowest coefficients. Only when you write the balanced full reaction do you need to make sure the electrons on both sides are equal (so they cancel out).
