ANSWERS:
They are both ionic compounds.
These compounds are made up of cations (positively-charged ion) and either or 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.
and 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 )
Mono and di are Greek numbers, mono means one, mostly u will find it for the thing which is like ONE, (Idk) Like, in maths you use Monomials,, which meAns one term, so like that.... and DI means two , mostly you will find it for two things,,, like in Science, DIoxide,,, so you need to oxides to make dioxide,, CARBON-DIOXIDE,,,
HOPE THIS HELPS!
