Name the common strong acid with chemical formula H2SO4.

Explanation:
H2SO4 is sulfuric acid, a very common strong acid. In water, a strong acid dissociates almost completely, so this compound readily donates a proton to form HSO4− and H+, with a subsequent proton dissociation from HSO4− contributing further to the acidity. This behavior makes the solution highly acidic. Among the choices, sulfuric acid is the one with the formula H2SO4. The other options correspond to hydrochloric acid (HCl) and nitric acid (HNO3), which are also strong acids but have different formulas, while phosphoric acid (H3PO4) is a weak acid.
