WebFeS (s)+2HCl (aq)→FeCl2 (aq)+H2S (s) A reaction mixture initially contains 0.216 mol FeS and 0.662 mol HCl. Once the reaction has reached completion, what amount (in moles) of the excess reactant is left? 0.230 mols Looking at the equation, we can see that the amount of HCl consumed is twice the amount of FeS. Ferrous chloride is prepared by addition of iron powder to a solution of hydrochloric acid in methanol. This reaction gives the methanol solvate of the dichloride, which upon heating in a vacuum at about 160 °C converts to anhydrous FeCl2. The net reaction is shown: Fe + 2 HCl → FeCl2 + H2 FeBr2 and FeI2 can be prepared analogously.
