boric acid
chromic acid
acid name: ; chemical formula: $ce{h_{2}cro_{4}}$
acid name: ; chemical formula: $ce{h_{3}bo_{3}}$
acid name: ; chemical formula: $ce{hc_{6}h_{7}o_{6}}$
acid name: sulfuric acid; chemical formula:
acid name: iodous acid; chemical formula:

Explanation:

1. For $\ce{H2CrO4}$, the polyatomic ion is chromate ($\ce{CrO4^2-}$), so the acid is named chromic acid.
2. For $\ce{H3BO3}$, the polyatomic ion is borate ($\ce{BO3^3-}$), so the acid is named boric acid.
3. For $\ce{HC6H7O6}$, this is the formula for ascorbic acid (vitamin C).
4. Sulfuric acid corresponds to the formula $\ce{H2SO4}$, as it contains the sulfate ion ($\ce{SO4^2-}$) with two hydrogen ions to balance charge.
5. Iodous acid comes from the iodite ion ($\ce{IO2^-}$), so its formula is $\ce{HIO2}$ (the "-ous" suffix indicates the lower oxidation state iodine polyatomic ion).

Answer:

1. Acid name: chromic acid; Chemical formula: $\ce{H2CrO4}$
2. Acid name: boric acid; Chemical formula: $\ce{H3BO3}$
3. Acid name: ascorbic acid; Chemical formula: $\ce{HC6H7O6}$
4. Acid name: sulfuric acid; Chemical formula: $\ce{H2SO4}$
5. Acid name: iodous acid; Chemical formula: $\ce{HIO2}$
