CHEMISTRY: Good luck tomorrow! Here’s the vodcast from today on our short test review. Poor Daphne and gummy bear!

Practice tonight, and make sure you have everything memorized. You can get help in memorizing the 17 types of chemical reactions on quizlet.com (and also on the polyatomic ions from last semester). Here’s a link to the 17 types of reactions on quizlet – http://quizlet.com/11793692/chemistry-chemical-reactions-flash-cards/. Thanks, Nicholas!!

Make sure you are also practice balancing equations. You can go to sciencegeek.net and find lots of interactive practice on balancing equations in the Chemistry Review Activities under Unit 3 and maybe some others. Also, the vodcast from today has the answers to the back page of Worksheet 4. Practice doing those, that will help a lot!

Another source of help is your online textbook at my.hrw.com. Click on the “Visual Concepts” or “Review Activities” tabs at the top of the chapter page for the extra tutorials and quizes. I love you and I’ll be praying for you!!

HON CHEMISTRY: Good luck studying for the test on chapter 11! Here are both the help session from this morning and the test review from today’s class. The first one is the help session. I think.

Have you made your “stuff to know, stuff to know how to apply, and stuff to know how to do” list? Here are the laws and people I can think of, can you think of any more? Boyle’s law, Charles law, Gay-Lussac’s law, combined gas law, Dalton’s law of partial pressure, Avogadro’s Law, Gay-Lussac’s law of combining volumes, and Graham’s law of effusion. And don’t forget pressure. Whew!

And don’t forget, working problems is great, but make sure you can apply the concepts! Good luck, I’ll be praying for you, you can do it!!

HON CHEMISTRY: Okay, for the record, water balloons do not obey Avogadro’s Law, but gas balloons do! Equal volume balloons contain the same number of molecules. Yay, another great conversion factor!!

How’d you like playing around with the ideal gas law? Super cool the way you maneuvered it around like that to use something like density!

Also – at the very end, after you left, I added a bit more about Graham’s law of effusion. I think you’ll find it a fairly easy formula to use. Don’t get stuck if it doesn’t give you specific masses or volumes. Remember what we did about that before.

Need some extra practice? Help session Wednesday morning at 7:15ish A.M. Now, go play with Henry’s Law!

HON CHEMISTRY: Wow, it’s been forever since I’ve had a chance to post – but I think I’m just about caught up on everything we’ve done so far with gases. Here’s the lecture on the rest of the gas laws – Charles law, Gay-Lussac’s law, and the combined gas law. I’ve had to pull one from the past, so let me know if it doesn’t work.

Any questions about the Boyle’s law lab? Let’s talk about gas stoichiometry tomorrow!

HON CHEMISTRY: I must say, it’s a bit odd talking about snowshoes in April! Here’s the lecture on the rest of pressure and on Boyle’s law.

CHEMISTRY: Hey guys, good luck studying for the pre-test tomorrow! Next some extra help or practice? Help session tomorrow morning at 7:15ish A.M.

SENIORS: Hey guys, I wish you the best as you prepare for you very last Skinner Exam! Click below if you need a copy of the exam review. I’ll meet you in the upstairs library Monday morning. Be sure to bring your cleaned out textbook (erased, cleaned out and in perfect condition!), a calculator, a pencil, and your card and paper if you are in physics.

Just in case you didn’t get the message, the following students are exempt from the 2nd semester physics exam: Corey, Zach, Matt, Andrew, Jakin, and Sebastian. Wow! Six! I think that’s a record. Good job, guys!

CHEMISTRY Exam Review 2 2012 – Seniors

PHYSICS Exam Review 2 2012

_____________________________________________

CHEMISTRY: How’s it going with balancing equations? Here’s the short review we did Friday on using the activity series when completing and balancing equations.

Remember these steps: #1 – write the correct formulas; #2 – ask yourself what type of rxn it is; #3 – find the rule that applies and go for it! Don’t forget also that if you answer single replacement to #2 (or the synthesis or decomposition of a metal oxide!) you’d better check the activity series first!! Good luck!

PHYSICS: Well, I’ll make it pretty later, but for now I thought you’d want to know:

The winners of the 2012 Rube Goldberg Competition are…………………… the sound group: Corey, Zach, and Matt. Congratulations, guys!!

And what you really wanted to know – so far, the following students are exempt from the 2nd semester physics exam: Corey, Zach, Matt, Jakin, and Sebastian. Wow! Five! I think that’s a record. Good job, guys!

CHEMISTRY: Can you believe we finished the chapter?!? Here’s the last lecture – the activity series. I’m sorry it took me so long to post it!

Practice, practice, practice! Don’t forget, you have to memorize the 17 types of chemical reactions and the activity series, but you also have to apply them! You need to know them so well, that it becomes second nature to you. I’ll be praying for you as you begin to study for the test!!:)
