Guida verificata passo dopo passo1
Understand that hydrosulfuric acid is a common name for a specific binary acid composed of hydrogen and sulfur.
Recall that binary acids consist of hydrogen and one other nonmetal element, without oxygen atoms in their formula.
Recognize that the chemical formula H2S corresponds to hydrosulfuric acid, which is also known as hydrogen sulfide when in gaseous form.
Note that formulas like H2SO3 and H2SO4 contain oxygen and correspond to sulfurous acid and sulfuric acid, respectively, which are oxyacids, not hydrosulfuric acid.
Therefore, identify H2S as the correct chemical formula for hydrosulfuric acid.
