Answer:

2. C

3. D

Step-by-step explanation:

2. Ionic bonds are chemical bonds that forms between the ions of molecules or compounds. The two molecules are joined together by an electrostatic force. This is the case of the bond that forms between the slight negative charge (anion) at one end of a water molecule and the slight positive charge (cation) of a second water molecule.

3. Cohesion refers to the attraction of a molecule to a like molecule. The cohesiveness of water molecule to another water molecule is great due to the HYDROGEN BONDS that forms between them.
