College Chemistry 101

Chemical compounds make up just about everything in the world. Discover how compounds form with two types of bonds: Ionic bonds and covalent bonds.

Chemical compounds are named using a system called chemical nomenclature. In this science lesson, apply this concept to naming four types of chemical compounds.

Chemistry studies atoms and molecules, which are tiny and seemingly impossible to count. But guess what? You can count them using a unit called the mole!

Chemical reactions are happening all around us. In this chemistry lesson learn how to use chemical equations to describe chemical reactions.

Stoichiometry is an important technique used in chemistry. In this lesson, aspiring scientists use chemical equations to make predictions about reactions.
