How do you balance #FeO + PdF_2 -> FeF_2 + PdO#?
It looks like you have already done it!
Let's check t to see if the equation is stoichiometrically balanced. Particles on left hand side:
Whether the reaction is reasonable is another matter. I presume this is a solid state reaction that occurs at high temperature.
In this context, just what do I mean by
