Hon Chemistry 3-31-17 Double Replacement & Combustion Reactions

Posted on by

HON CHEMISTRY: You realize what we did? We finished all 17 types of reactions today!

Careful when you work tonight’s homework! For all single replacement reactions and reactions involving forming or decomposing oxide, be sure and refer to the Activity Series. We’ll talk more about it after ExploreZone. Yes, you will get to memorize it!

Are you working on memorizing all 17 types of reactions?! 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!)

Chemistry 3-31-17 Ionic Bonds

CHEMISTRY: Isn’t this a beautiful crystal of copper sulfate pentahydrate? Since we’ve been talking about crystal lattice structures, I thought you might like to see something different than salt!

Here’s the lecture on ionic bonding and writing equations for ionic bonds. Remember, when you write ionic bonding, you’re not trying to arrange a single structure like you do with Lewis structures. Instead, you’re writing an equation that shows electrons being lost by one atom and gained by another atom. And make sure you put the dots in the right order!
