Section 2: Watch these two videos -
Intro to Gas Laws 1
Intro to Gas Laws 2
Then, do the following:
1) Come up with at least 5 examples of situations that you have witnessed in everyday life, which validate the properites described in these gas laws.
2) Now that you have three equations that relate pressure vs. volume, pressure vs. temperature and volume vs. temperature, see if you can create one equation that involves all three variables.
3) But wait! There's a flaw in your equation! There's a quantity missing that is keeping these equation from being sound for all types of gases. What is it???
4) Complete the worksheet handed out in class yesterday

Section 1: The videos above can also help you with your worksheets, since we moved pretty quickly through our notes on Gas Laws. I intentionally used the same examples in class as they use in the video, so if you need visuals of these phenomena, the videos are a great resource!

**Any absent student can pick up extra worksheets in the HMO on Friday.

Section 1: For quiz practice, complete the following problems from your textbook:
pg. 353 #20, 22, pg. 354 #27, 28, 30

So that you can check your work -
Answers: 20 - 84.3 kJ/mol.
22a - 21.8 mol, 22b - 253 g/mol.
27 - 8.85 kJ/mol.
28 - 2.65 x 10^5 kJ. 30 - 0.241g.

Thursday, March 22

Section 1: Study the notes you've taken thus far on states of matter.

Wednesday, March 21

All: Liquid crystals are substances that possess the combined properties of both liquids and crystals (remember solids can have a crystalline structure!). Do some research on liquid crystals and write a half to full page response considering the following:
-What constitutes a 'liquid crystal'? What kind of characteristics must a substance have to fall into this category?
-Give some examples of liquid crystals.
-What various uses are being found for these liquid crystals?

**Take this as an opportunity to explore science outside of our classroom environment, instead of viewing it as a chore. Include some sources at the bottom of your paper. I look forward to hearing about your research!**

Thursday, March 15

Section 2: Use your notes, your textbook and the powerpoint at the bottom of the page to complete 'Liquids and Solids Homework', which can be found under homework documents.

**Make up test will take place Tuesday morning at 7:30 in room 3K3**

Wednesday, March 14

Section 1: Make-up test is tomorrow morning, 7:30, room 3K3

Section 2: In your notebook, complete section review questions 1-6 on page 332 of your textbook. (Use your notes and section 1 of the textbook as your resources.)

Tuesday, March 13

Section 1: In your notebook, complete section review questions 1-6 on page 332 of your textbook. (Use your notes and section 1 of the textbook as your resources.)

Tuesday, March 6

All: Complete the chart on page 's8' of your lab manual. Remember that the volume of one mole of any gas (at STP) is 22.4mL. At the bottom of the page, write which reactant you believe to be the limiting reagent (you should use stoichiometry AND your lab observations to prove your hypothesis).

Monday, March 5

Section 1: As discussed in class, complete first two rows of data chart on page 'S8' on your lab.

Thursday, March 1

Section 1: On the worksheet handed out today, set up proportions for #3 (all parts) between moles of reactants in the balanced equation (coefficients!), compared to one of the given amounts of reactant. Like this:

I chose 3.6 mol as my given for no particular reason...if you want to use 5.3 - go for it!


**Do this assignment in pencil in case you make a mistake!
