CaS, CaBr₂, VBr₅, and V₂S₅.

Explanation:

The ionic compound should be neutral; the overall charge of it is equal to zero. Binary ionic compound is composed of two different ions.

Ca²⁺ can combined with either Br⁻ or S²⁻ to form binary ionic compounds.

CaS can be formed via combining Ca²⁺ with S²⁻ to form the neutral binary ionic compound CaS. CaBr₂ can be formed via combining 1 mole of Ca²⁺ with 2 moles of Br⁻ to form the neutral binary ionic compound CaBr₂.

V⁵⁺ can combined with either Br⁻ or S²⁻ to form binary ionic compounds.

V₂S₅ can be formed via combining 2 moles of V⁵⁺ with 5 moles of S²⁻ to form the neutral binary ionic compound V₂S₅. VBr₅ can be formed via combining 1 mole of V⁵⁺ with 5 moles of Br⁻ to form the neutral binary ionic compound VBr₅.

So, the empirical formula of four binary ionic compounds that could be formed is: CaS, CaBr₂, VBr₅, and V₂S₅.
