Cul (s) --> represents its state which means solid, Here Valency of copper is 1 so its cuprous.
<span>Fe2O3--> Ferric Oxide is a solid. Here valency of Fe is +3 so its Ferric </span>
<span>CoF2--> Cobalt Flouride is a solid</span>
<span>FeO --> Ferrous Oxide is a solid. Here valency of iron is +2 so its Ferrous. </span>
