Chemistry 2-6-24 Decomposition Reactions

CHEMISTRY: What!?! You mean there aren’t little green people on lonely country roads? 😉

Good job on decomposition reactions today! And then when we get to moving – I have to go and add guidelines from the activity series that complicate things. Really though – they just offer more explanation of what really going on in the world.

Here’s our discussion of the five decomposition reactions and the parts of the activity series that guide us through forming oxides and decomposing oxides.

Chemistry 2-1-24 Synthesis Reactions

CHEMISTRY: Wow! So that’s where the pretty light comes from! Great job with synthesis reactions.

HW UPDATE: Change the book homework for Friday night to this: Pg. 283 – 286: 17, 22, 38, and 40

Now go forth and practice what you learned! (The balancing equations part, not the playing with magnesium part!)

Hon Chemistry 9-12-13 Intro to Chemistry

HON CHEMISTRY: So now that you know how to use all the tools we’ll need in chemistry, it’s time to start talking about ….chemistry!!

Were you able to able to make applications with the branches of chemistry and categories of scientific work? We’ll finish talking about the properties of matter on Monday. Don’t forget to check your syllabus for homework. You might want to go ahead as soon as you can and begin memorizing the symbols of the elements, as well as the atomic numbers and mass numbers for elements 1 – 30. Is that something you’ve had to do in your other classes?

Now it gets interesting!

Chemistry 9-20-11 Intro to Chemistry

CHEMISTRY: We’re finally starting what chemistry is all about! Here’s the lecture from Tuesday on the intro to chemistry. Good job making applications with the branches of chemistry and types of scientific work! Make sure you have the vocab down, and be sure you’re able to apply what you learned today. Can you tell the difference between quantitative and qualitative, intensive and extensive properties, physical and chemical changes, etc.? Can you give me examples?

BTW – Have you started learning the symbols of the elements? Is that something you’ve had to do in your other classes? Don’t forget to check out the earlier webpost on It’s a great way to begin memorizing them! 🙂
