General Chemistry Concepts

Which molecular arrangements and energy levels lead to chemical reactions? Learn about collision theory and reaction mechanisms in this chemistry lesson.

In this chemistry lesson, learn Le Chatelier's Principle in which a system at equilibrium is changed and it shifts in a particular way to regain equilibrium.

When chemicals have forward and backward reactions, a balance between the reactions is called equilibrium; learn to predict equilibrium in this lesson.

What is molecular orbital theory? Join this chemistry lesson to understand and predict molecular structure and observe a demonstration of atom interaction.

Join this chemistry lesson to learn how acids and bases work on a molecular level, including how to measure the way protons are donated and accepted.
