Remember to carry out several places after the decimal and only round to the correct number of significant figures at the end. Don't forget to bring your homework assignment on Monday to turn in. Please let me know if you have any questions.
Remember that you need to know the equations for each topic above. Equations WILL NOT be given on the exam. Study using your homework and your extra practice worksheets. Don't forget to complete the problems again, don't just look at the answers!!!
This assignment is due on Monday, March 31st. Remember this is your homework over break. If you were in class on Friday, March 21st, you had your worksheets checked in during class. If you missed class, make sure you have the molarity/molality worksheet done when you return to class after break. Please let me know if you have any questions. Have a great spring break!!!!!!!!!!
Please complete the following problems for your solids and liquids homework assignment:
# 18, 20, 21, 26a, 27, 28, 29, 30, 31, 33, 34, 35
bonus = 32

The written portion of your test will take place on Monday, March 3rd. Please have your calculator and periodic table. There are 7 questions but please remember that we have shortened classes on Monday so you will only have 35 minutes to work. There will be questions on all of the gas laws that we learned. Remember that you will be given the combined gas law equation, ideal gas law equation and R value, and the graham's law equation. Let me know if you have any questions.
Check out the absent work section for answer keys and worksheets that we completed throughout this chapter!
Check out this document for answers to #20-24, 29, and 41-43 from the chapter review. Some of these questions were not assigned to you but would be good practice if you are looking for more practice problems.
For the scantron section (20 questions) that you will take Thursday, February 27th, here is a list of what you should focus on:
1. kinetic molecular theory of gases and ideal gases
2. relationship between kinetic energy and temperature
3. properties of gases
4. pressure and force (what are they, how they are related, etc)
5. scientists we discussed
6. the relationships between pressure, temperature and volume
Remember that our unit covers section 1 of chapter 10 and everything except section 4 of chapter 11. The majority of this test is focused on the beginning of the unit since the math portion will be on Monday. There is a question that asks you like a scientist with their idea so please be aware of that. Please let me know if you have any questions.
Are you looking to re-take the Stoichiometry Test?
If you did not do as well on the chapter 9 test as you had hoped to do, please know that you can re-take the exam. Please come to a review session on Monday, February 24th after 10th and 11th period in room 453 to ask any questions that you have.

For our unit on gases, here is your list of problems for the homework assignment:
pg 371 # 20, 29, 41, 42, 43, 50, 51, 52, 53, 54
This assignment is due on Wednesday, February 26th. Part 1 of the test will be on Thursday, February 27th and part 2 will take place on Monday, March 3rd.
As of right now, you may complete the first 5 problems. Remember that if you are converting units but staying with the same substance, you do NOT need a mole ratio or an equation. For #41-43, you are combining old conversions (mL <-> L, g <-> kg, etc) with the new conversion between moles and liters. We will finish up the chapter on Monday so you can complete the assignment for Wednesday.
Don't forget that your Charles's Law Lab is due on Monday, February 24th.
Please use the link to access the video. If you didn't bring your textbook home, there is a copy of the vapor pressure chart attached so you can still complete all of the problems from the Dalton's Law Practice sheet. If you lost your sheet (handed out in class on 2/20/14) please see the absent work page for another copy. Please let me know if you have any trouble accessing the video and come to class with any questions on Dalton's Law for tomorrow.
Please watch the following videos on the first 3 gas laws that relate the pressure, volume and temperature of gases. Please remember that you should be reading through chapter 10 section 1 and chapter 11. If you can't access the videos, the page numbers that specifically focus on that gas law are listed below that section. The practice worksheets can be found in the absent work section if you didn't get one in class.
The extra credit quiz for the third quarter will take place on Wednesday, February 19th (not Wednesday, February 12th like the syllabus says!).
The topics for this quiz are:
Alkali Metal and Alkaline-Earth Metals
You can find the information about these groups of elements in the element handbook section of your textbook on pages R2-R13. Remember there are 20 questions, you need to bring your own periodic table and calculators are not allowed. The quiz will begin at 7:30am so you can stop by anytime after 7:30 to take it. Please remember there will be no passes given to get students into first period late. Please let me know if you have any questions.
Please remember that we will review for the test on Wednesday, February 12th. Please come in with any questions about the homework assignments or coral sheet from chapter 9. Attached is the answer key to the part 1 homework. Let me know if you have any questions.
I'm so sorry that I copied the wrong solubility chart! Attached is the correct solubility table. Remember that aq = aqueous or soluble and s = solid or insoluble. There is also a shorter activity series on the top of the paper. This is a resource you should have with you everyday (along with your periodic table!) and can use on exams. Please do not write on it and let me know if you have any questions.
Here is a sheet of memorization tips that some found for one of my classes last year. While not every tip will work for your memorizing, there are a few good ones on there that might help you as you work to memorize. Please note that when they discuss the families, VI = 16 and VII = 17 in your notes and on your periodic table. Good luck studying!
Attached is the sheet with the common elements and symbols that you need to know for your quiz on Wednesday, September 4th. You received a printed copy in class, but please let me know if you can't open the attachment.
