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: Need some help balancing equations? Here’s day two of “How to write a balanced chemical equation.” And don’t forget – first, check and make sure you have the formulas written correctly. Then, if you can’t get the equation balanced, go back and check the formulas!! You can do this! 🙂
CHEMISTRY: Okay, maybe balancing equations isn’t exactly like this, but….. Here are the introductory notes on balancing equations. Plus – a couple of examples for practice. And, did I mention practice, practice, practice?
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: 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: 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.
HON CHEMISTRY: Do you need help balancing equations? Here’s a few minutes of practice doing just that. Don’t forget to first check to see if all of your formulas are correct. Then grab an eraser and practice, practice, practice! You can do it!! We’re going to crank it up a notch tomorrow!
