- 2. This property of water is due partly to the polarity of the water molecule. When it dissolves salt, the negative chloride ion is attracted to the water molecule's positive pole (hydrogen end) while positive sodium ion is attracted to the negative pole of the water molecule (oxygen end). This attraction causes the salt molecule to dissociate into its component ions.

- 6. intermolecular forces between water molecules on the surface of a liquid attract the water molecules toward each other to create a film
- 9. contains more electrons than protons
- 10. can occur between molecules or within parts of a single molecule. The former interaction occurs between water molecules. The latter interaction is important for maintaining the correct structure of large molecules.
