There are quite a few units to measure pressure in. And quite a few devices that can measure it. Ever think about a barometer? You will.

These lessons will provide most of what is covered in a typical introductory chemistry class. Bring your enthusiasm and let’s learn some chemistry!
Gases. Variable volume and variable shape make them the neatness state of matter. A lot of early understanding of chemistry was established through the study of gases...
The final intermolecular force is a strong sub-species of dipole forces called the hydrogen bond. No, it’s not a chemical bond. It’s another physical...
Now that we understand what makes a molecule polar or non-polar, we can talk about the kinds of physical interactions they can manifest with each other. Will it be the...
Understanding the polarity of a molecule is critical to understanding how that molecule interacts with its surroundings. But to understand polarity, one must first...
Ok, we’ve talked about Lewis Structures and we’ve talked about VSEPR. But wouldn’t it be nice if we could practice them together on the same molecules...
2D Lewis Dot structures are really handy, but not quite representative of the actual shape in the 3D world. With a little more work you can make those flat structures...
Once you feel pretty good about the basics of Lewis Dot, you might want to dig a little deeper. Explore molecules with odd numbers of electrons, decide among multiple...
So what happens when you run out of electrons in a Lewis Structure? You’re going to have to break out the double and triple bonds. And that is exactly where they...
The great chemist, Gilbert N. Lewis created a simple way to show how atoms in compounds (typically covalent) bond with each other. The trick to keeping it simple was to...
