Hon Chemistry 5-8-17 Molar Volume of Gases & Gas Stoichiometry

HON CHEMISTRY: Okay, for the record, water balloons do not obey Avogadro’s Law, but gas balloons do! Equal volume balloons contain the same number of molecules. And how about the Gay-Lussac’s Law of Combining Volumes? Yay, more great conversion factors!! How are you doing with blending the old and the new?

Hon Chemistry 5-3-17 Gas Laws

HON CHEMISTRY: Our first look at the gas laws: Boyle’s law, Charles law. No audio on the vodcast, so here’s a blast from the past. And you get a bonus – Gay-Lussac’s law. These guys did great work – and you’ve got to love their hair!!

Be sure you use Kelvin in the problems – not Celcius. And make double dog sure you use the formulas correctly! Rearrange that thing – no plug and play!!

Chemistry 5-3-17 Activity Series, Double Replacement & Combustion Rxns

CHEMISTRY: Wow! Can you believe we finished all 17! Here’s the lecture on the rest of the activity series and double replacement and combustion reactions. Now that you’ve got everything on paper, it’s time to practice!

Need some extra help? Help session? Let me know and I’ll be glad to schedule one!

Chemistry 5-2-17 Single Replacement Reactions & the Activity Series, Pt. 1

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 5-2-17 Kinetic Molecular Theory & Pressure

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 4-24-17 Synthesis & Decomposition Reactions

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!)

Hon Chemistry 4-28-17 Chapter 9 Test Overview

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. πŸ™‚

Below the vodcast for today is the help session from Friday morning. God bless you as you study!!!

Hon Chemistry 4-25-17 Percent Yield

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? πŸ˜‰
