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 wrote their unit test and handed in their lab report.
The lab report for yesterday's experiment is due on tomorrow. We performed an experiment to produce hydrogen gas today.
Homework: experiment discussion questions - due Friday Your unit test is on Friday. 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 We completed an experiment to show the use of Dalton's Law when a gas is collected over water.
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 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. To learn more about using the Ideal Gas Law, read p.484-488. The note for tomorrow can be printed from the "gas stoich lesson" document on the Unit 5 page of the site. 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. |
