Write the empirical formula of at least four binary ionic compounds that could be formed from the following ions: ca2+, v5+, br-, s2-

CaS, CaBr₂, VBr₅, and V₂S₅.

Explanation:

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

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

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

i think the answer is terrae but not 100 percent sure. ▓▬▬ §

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
