Section 3H: Complete the post lab questions from last night's worksheet and answer the following questions in your notebook:
1. What
is the molarity of a solution that contains 4.53 moles of lithium nitrate in
2.85 liters of solution?

flask contains 85.5 g C12H22O11 (sucrose) in
1.00 liters of solution. What is the
molarity?

beaker contains 214.2 grams osmium (III) fluoride in 0.0673 liters of
solution. What is the molarity?
5. Calculate
the molarity if a flask contains 1.54 moles potassium sulfate in 125 ml of
solution.
*Quiz corrections can be done for grades of 38 and below*
Kairos Students: Welcome back!
First, Read and take notes on page 401-406 in your textbook. Then, answer questions 1-6 on page 406.
Then, you're going to complete the first two pages of a worksheet on a phet simulation. Here's the link: http://phet.colorado.edu/en/simulation/soluble-salts
The worksheet that goes along with the sim can be found under Homework Docs. YOU ONLY NEED TO COMPLETE THE FIRST TWO PAGES. Start by just messing around with the sim so you can see how it works. Make sure to look at the information provided about the amount of salt and water on the right hand side. You will need to use the tabs at the top for the second page of the worksheet. Be sure the READ DIRECTIONS carefully throughout the worksheet!
NOTE: If you don't get the Pre-Lab Vocabulary definitions from the textbook first, you will have a lot of trouble completing the worksheet!

Section 3H: If you have not already, complete the ideal gas law worksheet. Also, on a piece of loose-leaf, explain how I crushed the can in class today (don't forget what you know about pressure, temperature, volume, energy, kinetic molecular theory, etc). Feel free to draw pictures to get your point across!
Also, study your gas laws ;-)

Welcome back from your long weekend and happy belated St. Patrick's Day from one of the fathers of modern Chemistry...an Irish scientist...a rock star...a gas law creator...you're about to learn about his work...you're gonna love him... (drumroll....)
ROBERT BOYLE!

Section 4H: For tomorrow: watch and take notes on these videos:
For Monday: Now that you know a bit about how a barometer works, you will design your own! Here's what you need to do:
On a piece of loose leaf, do the following:
1) Briefly explain how a barometer works, in your own words (you may draw pictures, if you'd like)
2) List materials you would use from around the house to create your own barometer
3) Draw a sketch of your barometer being sure to label all of the materials
4) Describe the aspects of your set up that your think will work well and those that could be improved. Make sure to include explanations of these inferences!
5) For extra credit - build it! You can take a picture of it OR bring it in!

Section 3H: Complete the back of the worksheet we started in class today. Also, read pages 343-344 in your textbook and take a look at the graph in Figure 14.
Students going on Montserrat: On Thursday we will look at a Phase Diagram. There are two videos on the phase diagrams below, and a great explanation in your textbook on page 347. The videos have the same content - I just put two because they are different styles of video - you only need to watch one (you can watch both if you'd like).
Practice reading a Phase Diagram in the worksheets under Homework Docs. If you feel lost on any of the 3 graphs you've seen, please make an appointment to see me.
