Lasleys, here is a simulation that can substitute for the lab: http://phet.colorado.edu/en/simulation/molecule-shapes Notice how you can rotate the images.    Notice the function of the lone pair of electrons, how their presence contributes to the shape of the molecules.


Brina, Anthony & Abel - You can watch the you-tube versions of what we did in class; take notes/diagram the experiments and try to explain the phenomena.

And now some simulations...http://phet.colorado.edu/en/simulation/gas-properties


The rest is all math, I'm afraid.  Reading textbook 13.1-13.4, and do these worksheets as you go along. You may not need to follow the book too deeply, and you can substitute any video tutor on the subject.


  1. Pressure Conversions  problems 1-5 write out the definitions of units [mmHg, torr, atmosphere, Pa] 
  2. Manometers problems 1-4
  3. Gas Laws Intro  All
  4. Boyle's Law problems 1-4
  5. Charles' Law problems 1-5
  6.  If you've received the Cartoon Guide to Chemistry, there are several pages about gases, pages 110-114
ANSWERS

Finally, if your cup is running over with homework, and your brain starts to get useless anyway, it would be OK to put off finishing, especially since there is a test on Thursday and you will want to go over Chapter 10-12.   That will mean more homework over break, however.  Definitely do some of it, or there will be no point to Monday's class.
