The answer is:
carboxylate
and protonated amines
The explanation:
when
The Carboxylic acids are polar . and the functional group carboxyl is formed from the hydroxyl and carbonyl group.
and about protonated amines:
-alkyl groups improve the basicity, aryl groups diminish it.
-Primary amides have an aromatic group or alkyl attached to an amino-carbonyl function.
- Primary amines are basic functions which could be protonated to the ammonium ion

Answer:
the molarity of MgCl2 = 6.073 x 10^-2 M
Explanation:
Molarity = mole (n) divided by volume of solution (V) in liter = n/v
mole (n) = mass (m) divided by molecular mass (Mm) = m/Mm
n of MgCl2 = 2.891/95.3 = 0.03033 mole
v of solution = 500 ml = 0.500 L
Molarity = n/v = 0.03033/0.500 = 0.06066 M = 6.07 x 10^-2 M
I don't think it's a pure substance maybe it's a mixture because to make a tea we use 2 or 3 ingredients
