Chemistry – Chapter 7 Part 1 Review, Kind of…

CHEMISTRY: How are you doing in studying for the chapter 7 – Part 1 test? The test review for this first part will be different – your review will be online! I’ve put an updated “Ch7 Stuff to Know & Know How to Do” sheet on Edline for you to use as your test review, and you can also click on the name here to open it. Also, I found a vodcast of an old test review from this chapter, and thought it might help as well; however, CAUTION, not everything I talk about on the old vodcast is going to be on your part 1 test. You WILL NOT have 1) percent composition, 2) empirical & molecular formula calculations, and 3) polymers, so fast forward through those parts, but you WILL have everything else. We’ll save those for part 2. The end of the vodcast has some sample questions and practice on oxidation numbers.

The BEST resource for knowing what will be on your Part 1 test is the updated “Ch7 Stuff to Know & Know How to Do” sheet on Edline. Wow! I know it seems like a lot, but you can do it! First priority – make sure you can write and name chemical formulas!!! Practice, practice, practice! Then start practicing the different kinds of problems – do at least two of each one of them. You can do it! I believe in you!! And I’ll be praying for you! 🙂

Chemistry 11-4-11 Mole Problems & Moles of Chalk Lab

CHEMISTRY: Great job on the moles of chalk lab! You set a land speed record for finishing a lab, and no hints. Good job! How’d you do on that mole problem worksheet? Here is a review of some of the problems.. At the end, it also has instructions for the lab, just in case you were out today. By the way, the lab can be written up on a sheet of paper instead of in your lab books.

Physics 11-3-11 Net Vertical Force

PHYSICS: So, would you ever jump out of a plane? Way too much craziness for me! How was net vertical force? Great job on the problems, but don’t forget things like terminal velocity and the why! And I still don’t know what’s so funny about a fish in an elevator?? 🙂

Chemistry 11-2-11 Moles, Mass & Molecules

CHEMISTRY: So how many water molecules are in that drop? Here’s the lecture from today on using molar mass as a conversion factor. You did a great job on the problems! Keep practicing them so you don’t forget!

By the way, were you ready for a quiz today? What about tomorrow? Don’t give up – keep working on memorizing polyatomic ions, acids, and the chemical names for those common substances you researched. Have you tried making a song?

Chemistry 11-1-11 Formula Mass

CHEMISTRY: So……’s it going? The good news is, you did a great job catching on to formula mass today. Bad news was getting that quiz back today! You’ve gotta, gotta, gotta learn those formulas. Flash cards, saying them as you write them a bazillion times, whatever it takes, you’ve got to memorize the formulas for the polyatomic ions and acids, especially those, as well as the other common compounds. That won’t be the last quiz, you know. (Hint, hint!!) And then there’s the test. And you have to know them to write formulas so you can calculate formula mass and molar mass. And for the next chapter so you can write balanced chemical equations. And for the next so you can do stoichiometry. Get my drift? You can do it, I believe in you!! Here’s the lecture on calculating formula mass. Calculators tomorrow!
