Kruka [31]

ANSWERS:

They are both ionic compounds.

These compounds are made up of $H^{+}$ cations (positively-charged ion) and either $NO_{3}^-$ or $SO_{4}^{-}$ 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.

$NO_{3}^-$ and $SO_{4}^{-}$ 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 $H^{+}$ )
