How many moles of FES2 are needed to produce 10 mol of F? E 203

Answer 1

The balanced chemical equation for the reaction is:

4 FES2 + 20 H2O -> 8 HF + 2 Fe2O3 + 16 H2S

From the equation, we can see that for every 4 moles of FES2, we can produce 8 moles of F.

Therefore, if we want to produce 10 moles of F, we would need:

(10 mol F * 4 mol FES2) / 8 mol F = 5 mol FES2

So, 5 moles of FES2 are needed to produce 10 mol of F.
