a) Iron (II) chloride and sodium sulfide undergo adouble-replacement reaction when mixed. Write a balanced chemical equation for the reaction.
b) If 40.0 g of iron (II) chloride and 40.0 g of sodium sulfideare mixed, what mass of iron (II) sulfide is produced?
c) What is the limiting reactant?
d) If 7.90 g of iron (II) sulfide is actually recovered, what is the percent yield for the reaction?
