CHEMISTRY: I missed you guys today! Sorry about the scratchy vodcast. How’s it going working with completing and balancing chemical reactions? Are you getting better at remembering how to write formulas? And how are you doing on memorizing the equations? And today you got a head start on the activity series. Good job!
Here’s a vodcast from today on the rest of decomposition (a couple of chem classes didn’t get all the way through) and all of single replacement. This makes 15 so far, so we’ll do the rest Monday! 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: Wow! So that’s where the pretty light comes from! Great job on synthesis and decomposition reactions. We’ll finish decomposition tomorrow. Now go forth and practice what you learned! (The balancing equations part, not the playing with magnesium part!) 🙂
UPDATE: Sorry the last vodcast had bad audio. Try this one and see if it works!
HON CHEMISTRY: So tell me again – how do you know if a chemical reaction has occurred? Poor Abraham red gummy bear! Here’s the lecture from the evidences of a chemical change and the intro to balancing chemical equations.
