Assign …study about Dalton’s Law of Partial Pressure by one of the following. 
Problems 52-54…ideal gas law and stoichiometry
   study examples page 194–199   Or watch
   Kahn Academy Partial Pressure Calculations videoLab Report….Finding Molar Mass of a Volitile Liquid.  
     If you were in the class where the chemical used did not produce quality resutults you may substitute the following data so you can have practice with the calculations.  Your lab reaport will be due next week (November 2)

Lab…Molar Mass of a Volitile Liquid

New AP Chem Blog

Assign due Friday  at end of class period 

 Ch  5 # 27-32, 34-36,38, 46—48

click on the comment button  and add comments…..feel free to help each other out…Your instructor will avoid providing too much information BUT YOU can help each other.

There have been several quetions raised about problem 2….
1.  You only have to do PART a ….other parts were not over topics we have studied yet.
2.  All the reactants listed in the problem are listed in the balanced net ionic equation….there is no error.

c.       Explain how each of the following would affect the empirical formula that could be calculated
        i.      some unreacted iodine condensed on the strip. 
       ii.      A small amount of white compound flaked off before weighing

If you did not get a copy of the test email me so we can get a copy to you.

Monday…
finish (or close to it) student presentations of problems from chapter 4.

Tuesday
–Start chapter 5 …see Chapter 5 tab above
–Turn in Labs…Purple Haze, Standardization of NaOH.
–Pick up take home test ch 1-4
Wed
–work on test…many students gone taking PSAT test

Select ch 4 solutions tabat the top of the page
          Watch the solution chemistry videos and take notes
                   If you do not have internet access come in before and after school to watch the videos in class

 Lecture (Thursday 1st Friday 2nd)

• Read pages 127-135
• take notes on vocabulary
• take notes on Sample exercises 4.1–4.3
• write formulas of all strong acids and strong bases

Lab    Net Ionic Equations

for all combinations of compounds that resulted in a reaction write:

1. formula equation
2. complete ionic equaion
3. net ionic equation

• check the blog or/and email me if you have questions
• come in for help if you have questions

We practiced using the solubility rules that you put in your notes on Thursday Sept 9 

• page 144
• know how to determine if an ionic compound is water soluble
• form a working knowledge of these rules   (memorize them)
