the formula of calcium oxide is CaO. What is the formula of the ionic compound containing calium abd sulfate ions

sineoko [7]

Answer:

$CaS$

Explanation:

Hello!

In this case, since calcium's oxidation state when forming ionic bonds is +2 and sulfur's oxidation state when bonding those bonds is -2, for the required formula we write:

$Ca^{2+}S^{2-}$

Now, since they have the same charge number, we infer the ionic compound formed when they bond is calcium sulfide:

$CaS$
