Answer:
Li₂S(aq) + SrI₂(aq) → 2 LiI(aq) + SrS(s)
Explanation:
Lithium sulfide and strontium iodide react through a double displacement reaction. In these reactions, the cation of one salt is exchanged with the cation of the other. The condition for a double displacement reaction to occur is that a precipitate is formed. Here, according to the solubility rules, strontium sulfide is insoluble, so this reaction is feasible. The chemical equation is:
Li₂S(aq) + SrI₂(aq) → 2 LiI(aq) + SrS(s)
