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.

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

The last test is over.  Begin to prepare for your examination.  If you have not yet handed in your Pop Rocks lab report, please do so tomorrow at the latest.

The equations of the gas laws will be written on the board for the test tomorrow, but you will need to know molar volumes and STP and SATP and the ideal gas constant.  Review questions from the text are on the previous homework blog entry.  Your Pop Rocks lab report was due today.  Sleep well!

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 Tuesday, June15, 2010.
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

We did the experiment found on the unit 5 page of this site.  The discussion questions must be handed in by Monday.

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.

We attended a presentation about nano science.  No homework today.

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.472-481 in the text for help.
Homework:  p.482 #5-7, 9
