5 Matching questions

  1. adhesion
  2. Dipole-Dipole Forces
  3. solution
  4. Miscible
  5. hypotonic solution
  1. a solution concentration is less than the cell fluid concentration
    - H2O flows into cell and it swells
  2. b force that exists between polar molecules
  3. c when two substances are completely soluble in each other at all proportions
  4. d attraction between unlike molecules (H2O and glass)
  5. e two or more components mixed such that the mixture is the same throughout

5 Multiple choice questions

  1. attractive forces between molecules
  2. solid to gas add PE
  3. IMF, temperature, pressure
  4. an extreme case of dipole-dipole interactions. Only occurs when hydrogen in directly bonded to N, O, F.
  5. conducts electricity (ions present)(salt)

5 True/False questions

  1. Titrationsway to determine the amount of a compound present by knowing a concentration and volume of one compound and the volume of the other

          

  2. solubility is effected bytemperature
    - solubility of a solid in a liquid increases with a temp increase
    - solubility of a gas in liquid decreases with a temp increase
    pressure
    - solubility of a solid in liquid is not effected by pressure
    - solubility of a gas in liquid increases with an increase in pressure

          

  3. intramolecular forcesforces between atoms within a molecule

          

  4. Boiling/Evaporationliquid to gas add PE

          

  5. Why are hydrogen bonds so important?an extreme case of dipole-dipole interactions. Only occurs when hydrogen in directly bonded to N, O, F.
