AP Chemistry
Today is the start of our Back to School lessons for AP Chemistry. I realize that you might find this to be quite the pain, but I believe that staying current on this basic stuff will benefit you greatly. Don’t forget, I still have to check my messages and respond to questions and correct answers to questions that you all post too. So, if I am going to use my summer vacation time for AP, then I must think it is pretty important.
Anyway, here we go…
Some of you have indicated that you would like to buy your book on-line but you need a number. I believe the book company is looking for the ISBN number. So, here is the title, edition and ISBN: CHEMISTRY AND CHEMICAL REACTIVITY, 5th edition, 0-03-033604-X. That should do it. If not, ask them specifically what they need and write it down and then call me or respond below.
For this week…
I am going to try to give you a day-to-day agenda to follow that I think is reasonable, but of course, you can go at the pace you would like as long as you finish through Section 1.3 by next Sunday (7/13).
Read the Preface to get an overview of the text. It is fairly important to do this each time you get a new college text. It gives you a good overview of how the text is laid out and what features it has that were designed to help you get the material in your brain. Don’t neglect this part. The SUPPORTING MATERIALS FOR STUDENTS is a good read as well. You can purchase extra things like the CD-ROM, Web-Based Learning System, Study Guide, Solutions Manual, Lecture Outline, Web Tutor, Power Points and Essential Math Tutorial to aid in your learning of the material. This is extra stuff that you do not necessarily need, but might help if you had.
Before you dive into the first chapter, take a look at the Preface to the Students. Skim this information as well. You might condsider stopping here for Day 1 on Monday 7/7/08. Or you can continue on.
Day 2:
Look over the Chapter Goals and Skim the Chapter Outline.
Read the Opening Essay (Out of Gas!) and respond to this essay in the Comment section below. Your response does not need to be a long, drawn out response. But respond to what you have read and any importance you have gleaned from the essay.
Look over the Chapter Focus on page 11 to make sense of this chapter’s main idea. Follow through the fill-in-the-blank notes up to the end of Section 1.2. Make sure to read and study all figures and side bars. If you do not have a CD-ROM, you will still be okay. The CD would just often give you a nice little video of what is being discussed in the chapter. You can stop here or continue on.
Day 3:
Complete the fill-in-the-blank notes for Section 1.3, completing all Excercises as they arise. The answers to the Exrecises are found in Appendix N starting on page A.40 in the back of the text. Now is the time to write a comment on anything that you do not understand in the Exercise sections. You may want to stop here or continue on.
Days 4-7:
Spend the rest of the week looking at the blue problems in the back of the chapter that you feel you can handle with the material you have read thus far. As always, use the Comment tab below to ask any thing you need to help you.
I will give you an end of section quiz question on Friday that is due in the comments section by Sunday at midnight. This, along with your response to the Opening Essay will be your grade for this week.
End of Chapter Question (this is a Marathon Problem that will incorporate all that you have learned thus for); this question is due at midnight on July 27th.
A cylindrical bar of gold that is 1.5 inches high and 0.25 inches in diameter has a mass of 23.1984g, as determined on an analytical balance. An empty graduated cylinder is weighed on a triple-beam balance and has a mass of 73.47g. After pouring a small amount of liquid into the graduated cylinder, the mass is 79.16g. When the gold cylinder is placed in the graduated cylinder (the liquid covers the top of the gold cylinder), the volume indicated on the graduated cylinder is 8.5mL. Assume that the temperature of the gold bar and the liquid are 86ºF. If the density of the liquid decreases by 1.0% for each 10.ºC rise in temperature, determine
a. the density of the gold at 86ºF.
b. the density of the liquid at 40.ºF.
