Can You Light A Fart On Fire?
Out of all the gases in our farts, hydrogen, and methane are the flammable ones. This means they can be set on fire. Even though you produce flammable gases, it isn’t enough to create a flamethrower. Humans can fart anywhere between...

Visualizing Molecular Geometry With 3D Software
We've already learned about VSEPR theory, and how to use it to predict the shapes of various molecules. But we didn't cover all of the molecular geometries for certain hybridizations, and we didn't talk about bond angles, so let's do...
