  5. saturated solution
  1. a contains max amount of solute that can dissolve in solvent
  2. b mass solute over mass solution
  3. c solid to liquid add PE
  4. d mass solute over volume of solution
  5. e temperature
    - 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

5 Multiple choice questions

  1. amount of energy required to stretch or increase the surface of liquid by a unit of area; strength of this "skin" is directly proportional to the IMF
  2. DNA is held together by H-bonds
    The reason why what has its unique properties
  3. liquid to gas add PE
  4. properties that depend only on the amount of the solute present, not on the type of solute.
  5. liquid to solid remove PE

5 True/False questions

  1. intramolecular forcesattractive forces between molecules

          

  2. Heat of hydration is exothermicproperties that depend only on the amount of the solute present, not on the type of solute.

          

  3. Molaritymoles of solute over Kg of solvent

          

  4. Consequences of IMF: Vapor Pressurestronger IMF give higher melting points

          

  5. Misciblea measure of a fluid's resistance to flow
    - strong IMF leads to high viscosities
