Answer:
D.
Explanation:
A concentrated solution is one that has a lot of solute (the substance being dissolved) in the solvent (the substance doing the dissolving). When a solution is concentrated, it means it has a high ratio of solute to solvent, so the answer is D.

Answer:
The pH is 4.76 (option C)
Explanation:
pH of a solution = TO BE DETERMNED
[sodium acetate] = 1M ; [acetic acid] = 1M
K = [H+] [A-] / [HA]
K = [H+] [1] / [1]
K = H
pH = pK
⇒ now pH is equal to pK
⇒ The value of pK is given which is 4.76
⇒ This means the value of the pH is also 4.76

Answer:
C-H groups can form weak hydrogen bonds and such compounds are more likely to have hydrogen bond donor groups because the hydrogen group is highly polar which is bonded to a strongly electronegative atom such as carbon, nitrogen and oxygen.
As the atom bonded with hydrogen atom have an equivalent partial negative charge, so it can only accept H-bonds from other atoms.
Thus, c-h groups forming weak hydrogen bonds are more likely to be hydrogen bond donor group.
