검증된 단계별 안내1
Understand that hydrosulfuric acid is a binary acid composed of hydrogen and sulfur.
Recall that binary acids consist of hydrogen and one other nonmetal element, and their formulas typically start with H followed by the nonmetal.
Recognize that the common name 'hydrosulfuric acid' corresponds to the compound formed by hydrogen and sulfur without oxygen atoms.
Identify the chemical formula for hydrosulfuric acid as \(\mathrm{H_2S}\), where two hydrogen atoms are bonded to one sulfur atom.
Compare the given options and confirm that \(\mathrm{H_2S}\) matches the correct formula for hydrosulfuric acid, while the others represent different compounds.
