Verified step by step guidance1
Understand that hydrosulfuric acid is a common name for a specific acid composed of hydrogen and sulfur.
Recall that the suffix '-ic acid' typically refers to acids containing oxygen, such as sulfuric acid (H2SO4) and sulfurous acid (H2SO3), which both contain sulfur and oxygen.
Recognize that hydrosulfuric acid is a binary acid, meaning it contains only hydrogen and one other element, without oxygen.
Identify that the binary acid of hydrogen and sulfur is hydrogen sulfide, which has the chemical formula \(H_2S\).
Conclude that the correct chemical formula for hydrosulfuric acid is \(H_2S\).
