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)
