Answer:
The answer to your question is below
Explanation:
a) Intramolecular forces are forces that hold the atoms within a molecule together, so, in the picture, we observe that these forces are covalent bonds between oxygen and hydrogen in the same molecule (continuous line).
b) Intermolecular forces are forces of attraction between two different molecules, so, in the picture, we observe that these forces are the hydrogen bonds between oxygen and hydrogen (dotted line).
c) Because water molecules are polar. Oxygen has a negative charge and hydrogen a positive charge, because of these charges water molecules can interact with the neighboring molecules.
d) In the picture we observe 4 dotted lines, we can conclude that each water molecule attracts by 4 molecules.
