Pressure and volume of a gas are inversely proportional at constant temperature.  Consult the text, p.424-434.
Homework:  p.435 #1, 3-6

This is the final unit in the course.  Read p.417-423 including margins.  Know the terms for each change of state.  Describe the three different types of motion and state which types of motion are in action for each state of matter.  You can view a simulation of the motions involved in each state at http://phet.colorado.edu/en/simulation/states-of-matter (click on "Run Now").  Make brief notes about Attractions Between Non-Polar Molecules and the Relationship Between Size and State, p.420.  Copy p.421 Table 11.1.  Write the Kinetic Molecular Theory (KMT) in point form, p.421. 
Homework:  p.423 #1, 3, 4, 7

The class time was used to review for the test on Monday. Review questions are listed on the May 19 blog.

We used kits to analyse samples of water from taps in various cities and towns, as well as untreated water, and compared the results.

We completed titrations to find the concentration of acetic acid in white and pickling vinegar.
The date of the unit test has been changed to Monday, May 30.
Homework:  Complete discussion questions #1-3 for tomorrow so we can share results for the two different vinegars.

acid + base ---> ionic compound + water
Stoichiometry can be used to determine concentrations and volumes of the reactants.  Refer to p.394-398 in your text.
Unit test is next Friday.
Homework:  p.398 #12, 13 and read p.399-401

We discussed the properties of acids and bases, and the Arrhenius theory of acids and bases, and strong and weak acids and bases.  The text reference is p.370-375 and p.381-383. 
The unit test will be next Fri., May 27. 
Homework: p.379-380 #1, 2, 7, 8; p.393 #2, 3, 7

Test Review:  p.410-413 #1-8, 12-15,17, 20, 23;  p.325-7 #1-5, 10, 18, 19;  p.365 #5, 20;  p.389 #9;  p.405 #3, 7, 15, 18

For this class, there was a choice of what level to work at: on the Unit 4 page of this site, download the "soln stoich lesson" file, and if you struggled to understand stoichiometry then print out page 3; if you were OK with stoichiometry print page 1; if you want a challenge, print page 2.  Go through the handout and use your text for reference as stated on the handout.  Homework is also on the handout.

We performed the experiment and began work on the discussion questions.  Check the Unit 4 page of the site for hints on how to complete the lab report, in the document "logic puzzle report".  The laboratory report is due on Thurs., May 19.
