Review...

Homework this week is to spend  three  45-minute periods  reviewing your chemistry textbook, chapters 1-17. (To be sure you understand me, that is, three periods of 45 minutes each.)  Vocabulary and summary pages, notes and worksheets, comic book guide, blog and maybe a few videos (but not too much time with videos.)  MAINLY TEXTBOOK.

Monday I will give out  a review exam.  I will also ask for a self-evaluation, reflection on your study habits, learning strengths and weaknesses, etc. How would you grade yourself?

I think I will skip homework on Redox reactions; so...just the review.

Main Idea for Oxidation-Reduction reactions: Follow the electrons--it makes all the difference.

Starting the Review:

• Here's the chemistry placement test study guide from SRJC (just 9 questions) - more like a quiz, actually.  http://www.santarosa.edu/app/placement/pdf/CHEM%20Study%20Guide.pdf .  Post your score below if you got an 8 or a 9. Correct, that is. Here the petition to take Chem 1A, the harder chem class, along with a few more questions. http://www.santarosa.edu/app/placement/English-Math-Chemistry/pdf/Chemistry%20Diagnostic%20Review%20Form%20Jan.2014.pdf

If you think you might like to take the placement test, sooner would be better than later; results are good for 3 years, although it may be different for chemistry, because to do 1A you must also petition.  You need to be a  JC student.

• Read Chapters 1 & 2 in the Cartoon Guide to Chemistry. It is not necessary to color, but you can if you want to.

• Le Chatelier Experiment:  Fill in as much of the Question section as possible, since you won't have much/any homework time this weekend.

• Collect and organize all worksheets and notes from chapter 17, Equilibrium.

• I have forgotten to collect the corrected tests from chapters 13-15.  Could you complete those and bring by Monday.  thanks.

Reducing Stress in Chemistry

l

need more?

finish up on the worksheets...skip the one on solubility and do the last two in the packet:

Are All Equilibria Created Equal? (print out this one, I did not give it to you)

Relieving Stress in Chemistry

Law of Chemical Equilibrium

answers to follow...

No added homework after the Rendezvous, but do read up on the experiment and be ready to go next Monday.

Don't Stress...

Homework (in this order):

1. Video/NOTES!

2. Worksheet 18-2 Writing an Equilibrium Expression answers

3. Reading textbook 17.6-17.7 pg. 548-554  (Be sure to thoroughly understand the difference between equilibrium constant and equilibrium position.)

4. Worksheet 18-3 Calculating Equilibrium Constants answers

5. Video: NOTES!

 

6. Worksheet 18-6 : Le Chatelier's Principle answers

Le Chatelier's Principle--it's all about relieving stress.

Don't worry; be happy!

This video is actually homework for the midsci class, but you might enjoy it too...

Overview of the next chapter: Equilibrium

Videos: IsaacsTEACH unit 11- Equilibrium  This is the playlist, includes 8 videos for the chapter, but 1-5 to start.  Take great notes, and keep them.
Reading: pages 527-537 ( Chapter 17 sections 1-5)  (in the car, at the beach???) UNDERLINE important bits to remember,



Also read through our experiment pages before Thursday, at least experiment A & B.

Don't you dare wait till Sunday!

ew.

Take a few moments to consider our "experiment" with the cabbage juice indicator and the household products;  we mostly played around, somewhat haphazardly, to find relative pH for each substance and then placed them on a pH scale.  Very pretty.  But we should ask ourselves a few questions, such as, How did concentration affect the pH? How could we have made this a better experiment? What did we really learn? Leave a comment or pose a question below. (yes, everyone.)

Review your notes so far from this chapter's videos (which should now be in a new section of your chemistry binder, right?)  and page through  textbook sections 16.1-4, making sure you know the vocabulary and summary.  Then practice calculating concentrations/pH conversions with the blue-letter Problems 30-36 at the end of the chapter on page 533. Remember the blue-letter problems have answers in the back of the book.

New reading: 16.5 through  16.8.  Worksheet  to accompany 16.7 Acid-Base Titration  answers to follow , but watch Isaac TEACH first:

Experience the Power of the [H+]!

STUDY HINT: When you study chemistry section by section in multiple homework assignments, spend a few minutes to review the chapter from the beginning before you go on to the next section:  the vocabulary, the summarizing points, and the math bits, in particular.  You will find that as you do so, what you once thought difficult will become more and more familiar, maybe even easy; you will understand the following sections more thoroughly, and you will automatically be prepared for the test.

Two worksheets that review yesterday's lesson:
http://www.csun.edu/~JTE35633/worksheets/Chemistry/19-1EquationsAcidBases.pdf
16.1 answers
http://www.csun.edu/~JTE35633/worksheets/Chemistry/19-2ConjugatePairs.pdf
16.2 answers
You don't need to do all the problems, just enough so you know you've "got it."  Also, print out this one:
http://www.csun.edu/~JTE35633/worksheets/Chemistry/19-3pH.pdf 
and the pH worksheet answers here.

To review or substitute for section 16.3, watch and take notes:https://www.youtube.com/watch?v=k6gpQy6H490 13 minutes MUST TAKE NOTES!  After this it will be easier to do the math problems from 16.3.  Do some of those.

Also watch: Take NOTES!

On to pH; more from Amy---> 18 minutes Helps with math and calculators.
https://www.youtube.com/watch?v=BM0SnHf97mg  
ABSOLUTELY you MUST follow along with your pencil and calculator!!!
This will cover the material from 16.4, now you should be able to do the worksheet printed out above. (19.3 pH) You may need to reference your textbook as well.
