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 $H^{+}$ )

Q. In an ________ solution, red blood cells ________. Group of answer choices:

Hyposmotic, lose water and shrivel
Isomotic, have a normal shape ✔️
Isosmotic, swell and may burst
Hyperosmotic, have a normal shape
Isosmotic, lose water and shrivel

$\large{ \boxed{ \bf{ \color{violet}{The \: correct \: answer:}}}}$

In an isosmotic solution, red blood cells have normal shape.

Option B

<h3>Explanation:-</h3>

Osmosis : The movement of the solvent or water molecules from a solution of their higher concentration to a solution of lower concentration through a semipermeable membrane.

❍ Depending upon the osmotic concentration, There are three types of solution and their result when cell is keot inside them:

Hyposmotic (Water enters, Swells up)
Isosmotic(Equal flow, No change)
Hyperosmotic(Water comes out, shrinkage)
