I'm usually okay when it comes to balancing equations but this one has me really stumped! Please help explain this to me.

  1. I expect your problem is that someone made a typo. I think that K2Fe(C2O4)3 on the right should be K3Fe(C2O4)3. As it stands Fe has an oxidation state of +4 which is not all that easy to explain but K3Fe(C2O4)3 Fe is +3 and the Fe goes from +2 on th left to +3 on the right. Look into that as the main source of trouble you are having. Check the rest of it for typos, too.
