Limiting Reactants example question
One way to produce hydrogen sulfide gas is by the reaction of iron(II) sulfide with hydrochloric acid:
FeS(s) + 2HCl(aq) → FeCl2(aq) + H2S(g)
If 10.2 g HCl is added to 13.2 g FeS, how many grams of H2S can be formed? What is the mass of the excess reactant remaining?
