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.  The topics covered on the exam are in the document "exam topics" found in the same place.  If you were absent, ask the teacher for your study sheet to bring to the exam.

Most students completed their test.
Molar Volume lab report is due tomorrow.

Students used this time to review for their test tomorrow.
The lab report for yesterday's experiment is due on Thursday.

We performed an experiment to produce hydrogen gas today.  Homework is discussion questions from the handout.  Your unit test is on Wednesday.

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 Wednesday, June 15, 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.
Homework:  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.

We discussed the composition of the atmosphere and contributors to air quality problems, such as greenhouse gases, and smog.  If you were absent, get notes and questions from another student when you return.
