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:

CaS
