Hon Chemistry 3-29-12 Double Replacement & Combustion Reactions

Posted on by

HON CHEMISTRY: You realize what we did? We finished all 17 types of reactions today. And we ended with a bang!? No, it was more like a whoosh!

Make sure you are working on memorizing all 17 of them by Monday – and forever! 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!)

Hon Chemistry 3-28-12 Decomposition Pt. 2 & Single Replacement Reactions

Posted on by

HON CHEMISTRY: You are doing a great job working with completing and balancing chemical reactions! How are you doing on memorizing them? And you got a head start on the activity series. Good job!

Here’s a lecture from today on the rest of decomposition and all of single replacement. That makes 15, so we’ll do the rest tomorrow! Careful though, 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!!

Chemistry 3-29-12 Molecular Geometry

Posted on by

CHEMISTRY – Who knew we’d be doing geometry in chemistry?!? Here’s the lecture on molecular geometry, with a little practice at the beginning on polyatomic ions and resonance. Molecular geometry is super easy. Make sure you know how to draw Lewis structures, then determine the type of ABE structure and you’ve got it. Easy-peazy!
