And here is some reading on gases: http://www.chemistryland.com/CHM130S/12-Gases/Gases.htm

STUDYING FOR THURSDAY'S TEST:  I've decided to limit the test to the material in chapters 11 -12, so review the Key Terms and Summary at the end of each chapter,  and especially the worksheets. Any questions?   If you would rather delay the previous homework till spring break in order to study for the test, that's OK with me. I will not be assigning additional homework for spring break. 

bad comma on 4.

And neither of them are wearing safety goggles.

Lasleys, here is a simulation that can substitute for the lab: http://phet.colorado.edu/en/simulation/molecule-shapes Notice how you can rotate the images.    Notice the function of the lone pair of electrons, how their presence contributes to the shape of the molecules.

Brina, Anthony & Abel - You can watch the you-tube versions of what we did in class; take notes/diagram the experiments and try to explain the phenomena.

And now some simulations...http://phet.colorado.edu/en/simulation/gas-properties


The rest is all math, I'm afraid.  Reading textbook 13.1-13.4, and do these worksheets as you go along. You may not need to follow the book too deeply, and you can substitute any video tutor on the subject.

1. Pressure Conversions  problems 1-5 write out the definitions of units [mmHg, torr, atmosphere, Pa] 
2. Manometers problems 1-4
3. Gas Laws Intro  All
4. Boyle's Law problems 1-4
5. Charles' Law problems 1-5
6.  If you've received the Cartoon Guide to Chemistry, there are several pages about gases, pages 110-114

ANSWERS

Finally, if your cup is running over with homework, and your brain starts to get useless anyway, it would be OK to put off finishing, especially since there is a test on Thursday and you will want to go over Chapter 10-12.   That will mean more homework over break, however.  Definitely do some of it, or there will be no point to Monday's class.

[Lasleys, sorry you're sick, you can do the lab from class at home - it is in the textbook on page 393]

 Take notes!

Wrapping Up Chapter 12: Understanding Molecular Bonds:
- review Key Words by writing definitions or "pictographs" for each word on the list (page 394)
-read Summary to make sure you "get" the major concepts for this chapter
-answer the Critical Thinking questions 53-60 at the chapter's end.
-do this worksheet: http://www.csun.edu/~jte35633/worksheets/Chemistry/6-3AtomicRadius.pdf

I would like you to turn in a packet of your work from this chapter on Thursday - please organize all your notes, worksheets and Q/A to turn in on Thursday.  Check past homework blogs to see if you missed any homework. Put everything in a cheapy folder.  Copies are acceptable.

Did you ORDER a copy of the Cartoon Guide to Chemistry???????

[maybe you should save this video for bedtime.  it is interesting but also very soothing.]

**********************************************************************

IF YOU TAKE NOTES WHEN YOU WATCH THESE VIDEOS, YOU WILL NOT NEED TO READ YOUR TEXTBOOK, EXCEPT AS A REFERENCE.  If you don't take good notes, it will go in one ear and out the other.  Literally.

 

and a worksheet: http://www.csun.edu/~jte35633/worksheets/Chemistry/9-6MolecularShapes.pdf

 

PART ONE of the homework:  World of Chemistry 8. Chemical Bonds   28 minutes 

PART TWO: watch this short video and finish up the worksheet from class, and then start reading chapter 12, sections 1-3 answering all the end-of-chapter questions and problems for those sections (page 394-395). Take notes as you read, including Key Terms and copy the illustrations.  I will probably add another video or two tomorrow.  thanks.

Take notes as you watch...Always take notes!

Also, order a copy of The Cartoon Guide to Chemistry from Amazon, or elsewhere. http://www.amazon.com/Cartoon-Guide-Chemistry-Larry-Gonick/dp/0060936770/ref=sr_1_1?ie=UTF8&qid=1394556301&sr=8-1&keywords=cartoon+guide+to+chemistry

PART TWO of the homework:  World of Chemistry 8. Chemical Bonds   28 minutes 

Electron Gofigurations

              

1. Textbook sections 11.9-11.11; also review the Key Terms and Summary on page 354. Videos are another option for sections 9-10; see below. (But do read section 11).

2. Worksheets handed out in class (3) The best way to understand is to practice the paradigm!  Also, here is site to check the difficult ones; and yes, there are exceptions! http://en.wikipedia.org/wiki/Periodic_table_(electron_configurations) Some of you will really hate this stuff, and others will find it oddly pleasant...I am one of the latter. Go figure.

3. "Questions for Analysis" from lab.

If the book is confusing and you would rather watch a video, here is a sequence that should be OK:
(If you find something better, let us know!)

So this teacher makes mistakes too!
