Chemistry 11-29-21 Oxidation Numbers (& Pre-Test Quiz Info)

CHEMISTRY: One man’s rust is another student’s lesson in chemistry! Great job today with oxidation numbers. Now it’s time to go and practice applying them! Try to do your homework without your notes first. Then go back and check and see what you actually knew. Great way to check up on yourself.

God bless you as you study for the Chapter 7 Memorization Quiz tomorrow! You need to have memorized (and be able to use!!): polyatomic ions, monatomic ions (but you can get these off the periodic table), acids, prefixes, and how to write and name chemical formulas. You do not have to know the chemical names and formulas for common substances. Click here for a copy of the PERIODIC TABLE you’ll use on the test – if you want to practice using it on your own.

That’s a lot, but you can do it! And make double dog sure you are working hard at practicing it all now!!

Physics 11-29-21 The Work Energy Theorem & Conservation of Energy

PHYSICS: See?! I wasn’t kidding about the balancing rocks movement!

Great job today on making connections between work and energy! I think you’ll like using the work-energy theorem, it’ll save you some time and a couple of steps. Don’t forget about friction!

Hon Chemistry 11-29-21 Polymers

HON CHEMISTRY: Oh, my word! We finally finished the chapter! Have you had a chance to check out the Chapter 7 Stuff to Know sheet?

Also amazing – did you realize molecules could be that large? And so many of them! Don’t you think polymers are some pretty unique compounds? Let’s play with them tomorrow!

Some items for contemplation: why are certain plastics recyclable and others not…and what about dishwasher and microwave safe?
