Question

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-

Answer 1

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-

Step-by-step 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.
