Hon Chemistry 4-18-19 Testing For Gases Lab

HON CHEMISTRY: Here’s a very, very short look at the positive tests for carbon dioxide, oxygen, and hydrogen gases for the experiment: Making and Testing for Gases. We’ll do the lab on Tuesday when we get back from Easter break. Make sure you have shown me the three balanced equations you’ll need for the experiment. I think you’ll have lots of fun with this one. πŸ™‚

Hon Chemistry 4-15-19 Double Replacement & Combustion Reactions

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. Yes, you will get to memorize it, but for the big test, not for the coming up quiz!

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!)

Hon Chemistry 4-12-19 Single Replacement Reactions & the Activity Series

HON CHEMISTRY: Moving right along with the 17 types of chemical reactions, here are the single replacement reactions – and you also got a head start on the activity series!

This makes 15 reactions so far, and we’ll do the rest on Monday. Careful though, memorize, 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!!

Lost Inside the Mponeng

Welcome to a great adventure! You’ve learned so much this year – not just concepts, but skills, and I can’t wait to see how you are going to apply it all!

Here’s the place where you can post your questions about the Lost Inside the Mponeng project so that everyone can see the answers.

First answer – the due date is Tuesday, April 30.

A really useful hint? Go back and re-read the project again – this time with a highlighter. It’s amazing how much I miss the first time I read something. So what’s your next question? πŸ™‚

Hon Chemistry 4-9-19 Another Look at Balancing Chemical Equations

HON CHEMISTRY: Okay, maybe balancing equations isn’t exactly like this, but…..

Are you starting to get the hand og balancing equations? Don’t forget to check the formulas first! πŸ™‚

Hon Chemistry 3-25-19 Ionic vs. Covalent Bonds, Pt. 2 & Metallic Bonds

HON CHEMISTRY: Molten iron, wow! Here’s the lecture on the rest of the notes on ionic vs. covalent bonding, followed by metallic bonding.

Aren’t you glad there are no structures to draw for metallic bonds?! Make sure you can use the electron sea model to explain the properties of metals. Also be able to compare and contrast all three types of bonds.

Have you made your own Chapter 6 “Stuff to Know Sheet”? Great way to get organized as you get ready for this test!!

Hon Chemistry 2-22-19 Ionic Bonding

HON CHEMISTRY: Hey guys, here’s the lecture on a different way that atoms come together – ionic bonding.

Keep in mind that 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!

Also important, pay close attention to the comparisons of ionic and covalent bonds – and WHY! And whatever you do, stay away from bubble baths if you have mortal enemies!
