Question

1. one side of the water molecule has a positive charge, while the other side has a negative charge. what do the charges indicate about the molecule? a. water is a polar molecule. b. water is a nonpolar molecule. c. water is an ionic compound. d. water is an ion. 3. bonds that form between water molecules are called ____ bonds. 4. true or false? hydrogen bonds are strong and require a lot of energy to break. 5. the tendency for water molecules to stick to other water molecules is called 6. a force that acts on the particles of a liquid at the surface is called 7. how does surface tension force the surface of water to curve?

Explanation:

1. Water is a polar molecule because of its bent - shape and the difference in electronegativity between oxygen and hydrogen, resulting in a partial positive charge on hydrogen and partial negative charge on oxygen. So the answer is a.
2. The bonds between water molecules are hydrogen bonds.
3. Hydrogen bonds between water molecules are strong and require a lot of energy to break, so the statement is True.
4. The tendency for water molecules to stick together at the surface is called surface tension.
5. The force that acts on the particles of a liquid at the surface is surface tension.
6. Surface tension causes the surface of water to curve due to the cohesive forces between water molecules trying to minimize the surface area.

Answer:

1. a. Water is a polar molecule.
2. Hydrogen bonds
3. True
4. Surface tension
5. Surface tension
6. Cohesive forces due to surface tension
