The remaining class time will be used for examination preparation.  Students are expected to use class time wisely.  The review questions from the text are found in the document "exam review" found by clicking on the link labelled SCH 3U on the left side of this page.

Complete your lab report for tomorrow.

Today we applied the gas laws to how popcorn pops.  complete the discussion questions for Friday.  Unit test is tomorrow.

Time was allowed to complete review questions.

We performed an experiment to produce hydrogen gas today.  Homework is discussion questions #1-6, 9 from the handout.

We now have a whole course worth of equations to choose from in solving problems.  Consult the example on p.492 for density, p.494-499 for molar mass, and p.507-509 for Dalton's Law problems. 
Your unit test is on Thursday, January 20, 2011.
Homework:  p.493 #16, 18; p.500 #20, 24; p.514 #6b
Review for test:  p.467-469 #2, 6, 8, 13, 16, 19, 24, 28, 33; p.521-523 #4, 5, 7, 12, 13, 16, 18, 20, 23

You now have five ways to find moles of a substance.  Two of those methods are from this unit:  n = PV/RT  and  n = V/molar V  both for gases only.  Consult the text p. 501-506, and answer p.503 #25-27; p.506 (see margin) #29, 32, 33; p.511 #36, 39.  If you feel very comfortable with this concept, try the extension question, p.500 #2.

The Ideal Gas Law allows us to do calculations involving moles of gas at any conditions.  PV = nRT
To learn more about using the Ideal Gas Law, read p.484-488.
Homework:  Read p.482-483.  How do the concepts of read and ideal gases differ?  Under what conditions do gases deviate from ideal gas behaviour?  Note the concept organizer on p.485. 
Answer p.487 #12, 15; p.488 #3, 4

One litre of any gas will contain the same number of particles at constant temperature and pressure.  Consult p.472-48, 501-503 in the text for help.
Homework:  p.482 #5-7, 9; p.503 #25-27

We worked through a handout and answered questions from the handout about Dalton's Law.  Homework is to complete the circled questions on the handout.
