Description
Use your basic understanding of equilibrium systems to try to solve some problems. You'll tackle two kinds of equilibrium problems: ones in which you are asked to calculate the equilibrium constant for an equation, and ones in which you are asked to find the equilibrium concentration of a reactant or product.

Description
Discover how isotopes, which are different atoms of the same element, can actually differ in their weight because they contain different numbers of neutrons in their nuclei. Also, learn how different kinds of elements are grouped into both general categories (such as metals and nonmetals) as well as specific chemical families, which then are arranged into the periodic table.
