For question 14.17, "Write balanced half-reactions for the redox reaction of an acidified solution of potassium permanganate and iron (II) chloride" ... How do you know which half reactions you are supposed to be using?

Potassium permanganate is KMnO4 and iron (II) chloride is FeCl2. Since both include a salt (K and Cl), they dissociate in solution into MnO4- and K+ and Fe2+ and Cl-. So for your half reactions you will use the ones involving MnO4- and Fe2+.
