Chemisty 5-4-12 Balancing Equations Practice

CHEMISTRY: How’s it going with balancing equations? Here’s the short review we did Friday on using the activity series when completing and balancing equations.

Remember these steps: #1 – write the correct formulas; #2 – ask yourself what type of rxn it is; #3 – find the rule that applies and go for it! Don’t forget also that if you answer single replacement to #2 (or the synthesis or decomposition of a metal oxide!) you’d better check the activity series first!! Good luck!

Chemistry 5-3-12 Activity Series

CHEMISTRY: Can you believe we finished the chapter?!? Here’s the last lecture – the activity series. I’m sorry it took me so long to post it!

Practice, practice, practice! Don’t forget, you have to memorize the 17 types of chemical reactions and the activity series, but you also have to apply them! You need to know them so well, that it becomes second nature to you. I’ll be praying for you as you begin to study for the test!!:)

Chemistry 5-1-12 Single Replacement, Double Replacement & Combustion Rxns

CHEMISTRY: Wow! We did a lot today in just a very short amount of time! Here’s the lecture on the review and new notes on single replacement (with a little intro to the activity series), double replacement, and combustion reactions. Now that you’ve got everything on paper, let’s play with them tomorrow. First, the quiz. Then you’ve got to remind me to show you this really cool demo on combustion rxns. I call it “flaming bubbles”! And don’t forgot – we’ll start with the quiz! Good luck studying, I’ll be praying for you!!

Hon Chemistry 3-30-12 The Activity Series

HON CHEMISTRY: Well, here it is, the last of the lectures from chapter 8. A couple of things – make sure you’ve memorized the activity series, but just as importantly, make sure you know how to use it! Those guidelines I gave you in class should really help. Good luck as you study for the test on Thursday! I’ll be praying for you!!

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

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!!

Hon Chemistry 4-12-11 The Activity Series

HON CHEMISTRY: Well, here it is, the last of the lectures from chapter 8. A couple of things – make sure you’ve memorized the activity series, but just as importantly, make sure you know how to use it! Those guidelines I gave you in class should really help. Good luck as you study for the test on Thursday! I’ll be praying for you!!
