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:
[tex]CaI_2[/tex]
2) Formula of calcium sulfide:
[tex]CaS[/tex]
3) Formula of aluminum iodide:
[tex]AlI_3[/tex]
4) Formul aluminum sulfide:
[tex]Al_2S_3[/tex]
These are the four ionic compounds that are formed.
