Question

a. water is a polar molecule. c. water is an ionic compound. b. water is a nonpolar molecule. d. water is an ion. 3. bonds that form between water molecules are called hydrogen|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? 8. the tendency for water molecules to be attracted and stick to other substances is called

Explanation:

1. Water is a polar molecule due to the unequal sharing of electrons between hydrogen and oxygen atoms, creating a partial - positive and partial - negative charge. It is not non - polar, ionic, or an ion.
2. Hydrogen bonds between water molecules are relatively strong and require a significant amount of energy to break.
3. The force that acts on the particles of a liquid at the surface is surface tension, which causes the surface of water to curve.
4. The tendency for water molecules to stick to other substances is called adhesion.

Answer:

a. Water is a polar molecule.

1. True
2. Surface tension
3. Adhesion
