CHEMISTRY: Good job today on single replacement reactions! And today you got a head start on the activity series. Good job!
We’ve done 15 so far – how are you doing on memorizing them?! Careful though, don’t just memorize. 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!!

HON CHEMISTRY: Who knew there could be so much to learn about gases! And we’ve only just begun! Here’s the lecture on the kinetic molecular theory. Remember, don’t just know, know why!

CHEMISTRY: Wow! So that’s where the pretty light comes from! Great job on catching up with synthesis and learning decomposition reactions.
I know we actually did them on two different days, but I thought it might be helpful to have both in one vodcast. Now go forth and practice what you learned! (The balancing equations part, not the playing with magnesium part!)

PHYSICS: How much fun!! How’d you like playing with color? So now, why is an apple red? So….here’s the lecture on color – colors of light, and colors of pigment.

HON CHEMISTRY: From Friday, here is our overview of the test. Again I want to emphasize – the majority of the test is basic reaction stoichiomety, limiting reactants and percent yield. Be sure and give that the most of your study time!
Also, review writing and balancing chemical reactions. Most of the stoichiometry problems will require that you begin by doing just that! There will be just one extra jumbo large problem. 🙂
Below the vodcast for today is the help session from Friday morning. God bless you as you study!!!

PHYSICS: Wow – how time flies when you’re having fun. Here’s almost the whole lesson on curve mirrors – all in one day! Well, it’s an introduction to curved mirrors anyway!

HON CHEMISTRY: So are you a cookie dough lover? Not me – I like my cookies crispy!
Here’s the last of the applications of stoichiometry problems – percent yield. Lots easier that limiting reactants I think. You realize what we’ve done… we’ve finished the chapter!!
Not only that, did you get a heads up on designing the percent yield of magnesium oxide lab for tomorrow? 😉

PHYSICS: So much fun with light! Here’s the lecture on the characteristics of light, polarization, reflection and plane mirrors. We’ll play with mirrors and the reflection of light a bit more tomorrow!

HON CHEMISTRY: So if you have 11 roller wheels, how many roller blade skates can you make? You know, really, limiting reactant is almost that simple. Well, the concept is anyway! You deal with limiting reactants in your life all the time. Now we’re just applying that same concept with chemical reactions! 🙂

HON CHEMISTRY: I missed you today! Here’s your first lecture on reaction stoichiometry. Were you able to apply what you remembered about moles from earlier this year? Don’t forget the keys! Now all you need is some practice and you’ll have it down pat!!
