# How do you balance FeO + PdF_2 -> FeF_2 + PdO?

Let's check t to see if the equation is stoichiometrically balanced. Particles on left hand side: $F e + O + P d + 2 \times F$. Particles on RHS: $F e + O + P d + 2 \times F$. So your equation is indeed stoichiometrically balanced.
In this context, just what do I mean by $\text{stoichiometric}$?
