Holt’s Science Kids
Make sure you purchase a 3-ring binder, paper, dry erase markers, 3-hole punch, two composition books and a scientific calculator.
Ap Chem
Sorry the blog is not working properly, so there are no notes to copy.
Read the chapter starting on page 165 section 5.6 and continue on for the rest of the chpater.
Carefully read the chapter and fill in the notes. Do not look for key bolded words to fill in the blanks. You are expected to have a good understanding of this material on Thursday or Friday, depending on when we get back.
Any questions…
Practice with Reactions
Here is a site that has bunches of worksheets to try…do them all if you need to
Tuesday Study Session Web Site for Help on Empirical Formulas
Click on this site to practice empirical formulas problems before the retake. Remember to try 9-12.
Answers…
9…C5H7N is emp, C10H14N2 is molecular
10…HgC2H3O2 is emp, Hg2C4H6O4 is molecular
11..SrSO4 is the emp and molecular
12…C21H22N2O2 is the emp and molecular
Make Ups for General and Honors Chemistry
Remember we are having a review day for naming compounds and writing chemical equaitons on Monday, November 16th. On Tuesday, November 17th, we will be having a review over mole conversions, percent composition and empirical formulas. YOU MUST BE AT ONE OF THESE SESSIONS IN ORDER TO RETAKE A QUEST.
We are starting stoichiometry notes with a cool lab by the end of next week maybe. Read the packet I gave you to be ready for class on Monday.
HW for Honors and General Chemistry
Honors Chemistry…this is your HW questions…
Write the formulas for:
silver chloride
potassium nitrate
magnesium oxide
lead (II) nitrite
gold (I) hydroxide
ammonium sulfate
oxygen difluoride
carbon tetrabromide
General Chemistry make note cards for the following polyatomic ions:
ammonium, acetate, carbonate, chlorate, chlorite, dichromate, hydrogen carbonate, hydrogen sulfate, hydroxide, chromate
Week of September 21, 2009
This week in AP Chem will be a continuation of last week’s learning about the nucleus of the atom and why it splits.
The problem set will be due on Wednesday and Review Day will be on Thursday. This will set us up for our 2nd Quest on Friday.
In Physics this week, we will begin moving from linear motion to non-linear or projectile motion. This is found in CH 3. A variety of problems will be done throughout the week in class and we will be performing a few activities outside “throwing” projectiles. By the end of the week we will be in the lab working on our projectile tossing apparatus. Our second Quest will be done sometime next week.
In Honors Chem we will build upon our knowledge of chemistry by understanding matter and the way it can be changed. The periodic table will be a focus for us as well.
General Chemistry will focus on Matter and we will be completing Reviews 1-4 throughout the week. A lab is scheduled for mid to end of the week and our next quest will be early next week or the end of this week.
Work for the Week of September 14th…
AP Chemistry…we will be discussing the nucleus and the changes that exist due to radioactive isotopes. This is Chapter 23 and you should be reading from the text each night. The problems that we will be working on will be 3-10, and 13-53 odd. The problems should be completed by Friday at the latest, but you should be working on them as you are able each night.
Physics…we will be finishing up our unit on Linear motion. We will do a couple of activities to try to understand the ideas of hang time and free falling objects. You will be given problems in class to work on, as well as, questions to take home as needed. Quest 1 will be on Thursday.
Honors Chem…we will be finishing up Unit 1. In class Monday will be a Review Day and Tuesday will be the Quest. Wednesday – Friday we will be starting Unit 2 over Matter. You will have to know about 50 element names and symbols for a Big Quiz on Monday–I will give you the elements a little every day. Check with me for HW as the week progresses.
General Chem…Our first Quest is on Wednesday so we will finish section 6 of unit 1 on Monday (HW-Rev 6), then Tuesday we will review and Wednesday will be the Big Day. Thursday and Friday will be the 2nd Unit on Matter. I will give you a variety of elements that you will need to know the name and symbol for during class on Thursday and Friday.
