AP3 and AP4: LOTS of real life stuff. Review Thursday or Friday (whichever day you have class) Test is Monday.
H8: gas properties, measuring pressure

Tuesday, December 15th
AP classes: some technical difficulties with the projector today so we went “old school” with the board. I have recreated (simply) the notes we took and they are posted.
Specifically we discussed van der Waal’s equation and some real world stuff (straws, Juicy Juice, three bottle Monty, suction cups, etc)
H8: Boltzmann diagrams and the South Street Effect.

Monday, December 14th
AP4 and AP1: finished Graham’s Law, discussed Dalton’s law (and three types of problems), gas stoich problems and non-ideal behavior.
H8: Charles Law lab (you need to graph length v. Temperature and then use the line of best fit to calculate the temperature at which the length would have been zero).
H8: in class we discussed intermolecular forces, including ion-ion, dipole-dipole, ion-dipole, London Dispersion forces, ion-induced dipole forces, dipole induced dipole forces and hydrogen bonding. We discussed the change in strength of London dispersion forces based on size and on length (surface area) and we ranked the forces from strongest to weakest.

AP1: mole percent oxygen in air lab. Discussed IF problems, PV=nRT, gas density and Graham’s law (please do the Peterson football field problem before Monday’s class).
AP3: Dalton, gas stoich and non-ideal behavior

Thursday, December 10th
AP3 and AP4: Mole percent oxygen in air lab (Lab Write up due at 11:59PM to TurnItIn.com next Thursday evening, December 17th). We also discussed IF problems (AP4 only), PV=nRT, gas density and Graham’s Law. I expect answers to the Peterson problem next class.
H8: Test on moles
December 9, 2009
Wednesday, December 9th
AP classes: laws (Boyle, Gay Lussac, Charles, Foos, Avogadro) what and why.
AP3: also did IF problems
AP1 and Ap4 also did Kinetic Molecular Theory
H8: reviewed for tomorrow’s test
December 8, 2009
Tuesday, December 8th
AP4 and AP1: into to gases, gas properties, measurement of pressure, vacuums and forces
H8: Boyle’s Law lab – graph of P v. V will be used later. Finished moles (calculating molecular formulas and formulas of hydrates) Review tomorrow
