Answer 1

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.
