Write two balanced half-reactions for this redox equation: fe + cl2 → fecl3

First we need to write a balance equation for this redox reaction

In the above reaction on reactant side has oxidation state 0, while on the product side it has an oxidation state of +3. On the other hand, has oxidation state of 0 on reactant side and an oxidation state of -1 on product side.

The metal   loses electrons to form ion and is oxidized. So we write an oxidation half reaction.

and the   molecule gains electrons to form ions and is reduced. The reduction half reaction is
