  1. The K(sp) of a salt is the equilibrium constant for teh dissolution of that salt. It describes a saturated soln in which teh aqueous ions are in equilibrium with the solid..
  2. If the K(sp) is smaller, then it is _______ soluble.
  3. Solid nitrogen contains only _______. Methold has ________ and _______.
    • covalent bonds
    • covalent bonds and intermolecular interaction
  4. When entropy decreases, (delta)S is __________ .
  5. The ideal gas law assumes that molecular volumes and intermolecular attractive forces are negligible.
  6. Which group reacts most violently with cold water?
    alkali metal
  7. If the distance in front of a converging lens is greater than the focal length, what kind of image is formed by the lens?
    real and pointing down.
  8. Equation for work.
    Work = force x distance.
  9. What is the equation for gravitational acceleration?
    g = GM/r^2
  10. For a chemical reaction that is spontaneous in the forward direction, K >1 and G < 1.
  11. Mn is reduced (the oxidizing agent) from +4 to +2; O is reduced (reducing agent) from -1 to 0 in O2
  12. The solution with the lowest freezing point is the one with the highest concentration of particles.
  13. The chemical behavior depends on electron interactions and bond formation. The number and configuration of electrons depends on the element which is solely determined by the atomic/proton number.
  14. Electric field = Volts / distance
  15. The phase difference to a half of a wave is 180 degrees. Half a wave difference in phase between two waves corresponds to destructive interference.
  16. polar dissolves in polar; nonpolar dissolves in nonpolar
  17. Neutrons are uncharged and cannot be ionized.
  18. Cascading electrons are used to amplify signals
  19. 120 dB = 10log(I/I(o), log(I/I(o)) must equal 12 and I/I(o) is 10^12.
  20. Funtion of the liver:
    • 1. absorption of fats in the small intestine
    • 2. production of bile
    • 3. detoxification of poisons
  21. Mutations are heritable changes in the sequence of the nucleic acid component of chromosomes, and mutations that lead to unregulated cellular growth can lead to cancer.
  22. Fractional distillation separates compounds based on their.....
    boiling points
  23. Freezing point is the same as melting point.
  24. Hybridizationg requires base pairing between complementary nucleic acid sequences.
  25. Transcription occurs in the nucleus. Translation occurs in the ribosome.
  26. female life cycle: fertilization, birth, puberty, menopause. Mitotic divisions of oogonia that lead to formation of primary oocytes occur between fertilization and birth.
  27. A diploid, nondividing cell is most likely in G(0) or G(1), in which the cell remains metabolically active but is not replicating its DNA or dividing.
  28. A positive antibody test for a bacteria does not mean that a person must currently have a bacterial infection. It only means that the person exposed to the bacteria at some point, regardless of whether the person developed an ulcer and regardless of whether the person is still infected with the bacteria.
  29. Bacterial cells and human cells both have the ability to produce ATP via ATP synthase.
  30. The Grignard reagent will react with alcohols and compounds containing carbonyl groups. It will not react with ethers.
  31. The poorer the leaving group, the higher the proportion of Hoffman orientation.
