  1. Main forces between water molecules?
    Hydrogen bonding
  2. Water ability to disolve an ionic compound?
    Water is a polar molecule with a negative end and a positive end. The hydrogen atoms have a partial positive end and the oxygen atom has a partial negative charge.

    K2O
  4. Carbon tetraiodide
    CI4
  5. Iron(III) carbonate
    Fe2(CO3)3
  6. Nitrogen trichloride
    NCl3
  7. Silver sulfate
    Ag2S
  8. Molar mass
    Add atomic weights
  9. How many moles?
    ?/grams given = 1mole/grams molar mass
  10. Storage form of carbohydrates in animals
    glycogen
  11. Not digestable in humans
    cellulose
  12. contains both a (1-4) and a (1-6) glycocidic bonds

  13. Contains only 1 (1-4) glycosidic bonds
    amylose
  14. Contains only b (1-4) glycosidic bonds
    cellulose
  15. Contains both b(1-4) and a (1-6) glycosidic bonds
    none
  16. storage form of carbohydrates in plants

  17. alpha
    oh group down
  18. beta
    oh group up
  19. conpared to saturated fatty acids, fatty acids with a cis carbon-carbon double bonds
    have lower melting points because cis carbon bonds don not allow for good packing
  20. True or false? d glucose and l glucose are enantiomers
    true
  21. C=O with an H
    Aldehyde = AL ending
