QUESTION

# Write the correct chemical formula to distinguish between?..... calcium sulfide and calcium hydrogen sulfide

CaS, "calcium sulfide........."

Ca(HS)_2, "calcium hydrogen sulfide........."

Calcium forms a Ca^(2+) ion, and thus requires 2 negative charges to form a neutral salt. The salts of H_2S could be sulfides, S^(2-), or hydrogen sulfides, HS^(-).
