Question

quiz 3_chap 7: covalent molecules
what is the acid within the chemical formula, h₂so₄(aq)?
○ hydrogen sulfide acid
○ chloric acid
○ hydrosulfuric acid
○ sulfuric acid

Explanation:

To identify the acid from the formula \( \text{H}_2\text{SO}_4(\text{aq}) \), we recall acid naming rules. For oxyacids (acids with oxygen), the name is derived from the polyatomic ion. The sulfate ion is \( \text{SO}_4^{2-} \), so the acid is sulfuric acid. Hydrogen sulfide acid (or hydrosulfuric acid) corresponds to \( \text{H}_2\text{S} \), and chloric acid is \( \text{HClO}_3 \), so they are incorrect.

Answer:

D. sulfuric acid (assuming the options are labeled A to D as: A. hydrogen sulfide acid, B. chloric acid, C. hydrosulfuric acid, D. sulfuric acid)
