Across
  1. 1. A molecule in which the opposite ends of the molecule have opposite charges. This is due to unequal sharing of electrons between the atoms in the molecule.
  2. 3. Attraction between like molecules (ex: water being attracted to other water molecules).
  3. 4. When these substances are dissolved in water, they have a pH > 7. and donate OH-.
  4. 7. This type of bond is a weak intermolecular force. It is the attraction that occurs between water molecules.
  5. 8. A substance in living tissue that resists change in pH.
  6. 9. Attraction between unlike molecules (ex: eater being attracted to glass).
  7. 11. The film that is created at the surface of the water as water molecules cling tightly together.
Down
  1. 2. The upward movement of water through small tubes, against the force of gravity.
  2. 5. When we sweat, the water molecules in the sweat absorb heat from the body and thus our body temperature is lowered.
  3. 6. How much solute is in a given amount of solution.
  4. 10. when these substances are dissolved in water, they have a pH = 7 and donate equal amounts of H= and OH-.
  5. 12. When these substances are dissolved in water, the have a pH < 7 and donate H+.
