Stoichiometry

Tue, 8 Dec 2009 22:01:50 -0600

This approximately 25-minute podcast introduces you to the wonderful world of stoichiometry. You will need to recall how to utilize moles, molar masses, and balance equations. I have some fun images and music in this one just to add some flavor. There are four problems worked out step by step for your enjoyment.

Reaction Types

Wed, 2 Dec 2009 19:50:51 -0600

This approximately 20-minute podcast introduces you to types of reactions. You have previously learned how to balance chemical equations, and now you will learn the types of reactions and how to predict products when given reactants.

Empirical & Molecular Formulas
