    Answer:

    Write the empirical formula of at least four binary ionic compounds that could be formed from the following ions: Ca^2 , Al^3 ,I^-,S^2-

    Explanation:

    1)Formula of calcium iodide:

    The compound of Ca^2+ and I^-1:

    CaI_2

    2) Formula of calcium sulfide:

    CaS

    3) Formula of aluminum iodide:

    AlI_3

    4) Formul aluminum sulfide:

    Al_2S_3

    These are the four ionic compounds that are formed.
