What is the Molecular, Ionic and net Ionic for Li2S+FeI-->LiI+FeS?

This is a double replacement (double displacement) reaction in which two aqueous of lithium sulfide and iron (II) iodide react to produce the precipitate iron (II) sulfide as described in the explanation.

The chemical formula for iron (II) iodide is ##"FeI"_2"##, not ##"FeI"##.

Molecular Equation The overall balanced equation.

##"Li"_2"S(aq)+FeI"_2("aq")####rarr####"2LiI(aq)"+"FeS(s)"##

Complete Ionic Equation Includes all of the ions, including those that did not participate in the reaction to form the precipitate.

##"2Li"^+("aq")+"S"^(2-)("aq")+"Fe"^(2+)("aq")+"2I"^(-) ("aq")####rarr####"2Li"^+("aq")+"2I"^(-)("aq")+"FeS(s)"##

Net Ionic Equation Includes only the ions that participated in the reaction to form the precipitate.

##"Fe"^(2+)("aq")+"S"^(2-)("aq")####rarr####"FeS(s)"##
