ANSWERS:
They are both ionic compounds.
These compounds are made up of [tex]H^{+}[/tex] cations (positively-charged ion) and either [tex]NO_{3}^-[/tex] or [tex]SO_{4}^{-}[/tex] anions (negatively-charged ions).
Their names both end in -ic acid.
Acids are named based on their anion. With acids like these where the anion is attached to a hydrogen cation, we name such acids with the the suffix “-ic”.
They both contain polyatomic ionic.
[tex]NO_{3}^-[/tex] and [tex]SO_{4}^{-}[/tex] are both polyatomic ions.
"Poly-" = many
"ions" = have a + or - charge
So, yes, these are ions that are made up of several atoms (not just one atom like [tex]H^{+}[/tex])
