Hon Chemistry 1-13-21 Double Replacement & Combustion Reactions

HON CHEMISTRY: You realize what we did? We finished all 17 types of reactions today!

Are you working on memorizing all 17 types of reactions?! But don’t just memorize them. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!! (and yes, I realize I am repeating myself, but I do and you can!)

Physics 1-13-21 Collisions Problems Review 2

PHYSICS: Great job with some of the more advanced momentum and energy problems! Here’s a look at the student in the middle of a frozen pond, bird on the wire, and car crash with coefficient of friction.

Ready for the test? Take another look at some of the concepts!
