Chemistry 2-8-24 Single and Double Replacement & Combustion Reactions

CHEMISTRY: You realize what we did? We finished all 17 types of reactions today! Have you been practicing using them?

Are you ready for the quiz tomorrow? Have you been working on memorizing all 17 types of reactions?! Just the 17 reactions will be on the quiz Monday, but what about the chapter test coming up? For that, 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 2-8-24 Structure of the Atom

HON CHEMISTRY: So how to you find something you can’t see? Here’s the lesson from Thursday. Be sure and follow the connections the scientists made as they discovered the structure of the atom. Do you think there could be anything smaller than protons, neutrons, and electrons? Hmmmmm……

Make sure you know the name of the scientists, the name of their experiments, be able to draw a diagram of their experiment, and describe how they interpreted the experimental results that led to their discoveries.

Here are some extra video clips to go with the lesson for today. They’ll help you review the different experiment that the guys like Thompson and Rutherford did. Click here for the video on the Cathode Ray Tube Experiment that Thompson did, and also for a little history on The Discovery of the Electron. Here’s the other one on The Discovery of the Nucleus.

By the way – do you think you could do what they did – figure out what something’s made of without seeing it? Hmmmm….

Physics 2-8-24 Rotational Dynamics, Pt. 1

PHYSICS – Wow! Could you do this? Here’s the lecture on rotational inertia, angular velocity, and angular momentum – rotational dynamics! We’ll pick up the conservation of angular momentum tomorrow. Fun times!

By the way – I wonder how all this applies to other rotating things…like maybe the Earth? Hmmmmm……
