In this program, stoichiometry goes swimming. The topics of molarity, dilution, acid/base reactions, titration, limiting reagents, and yield—theoretical, actual, and percent—are all carefully examined. Practical problems involving the Molarity Equation give the program a quantitative analysis flavor, while “Cooking with Professor Rowley” and other skits present key stoichiometric concepts with a dash of levity. (33 minutes)

In part one of this program, chemistry authorities, including "Helium Man" and two janitors, lay down the law-Boyle's Law, Graham's Law, and Dalton's Law. They also present the Kinetic Molecular Theory and the Ideal Gas Equation and elaborate on part...(more details)
 
Moles, Percent Composition, and the Empirical Formula
View Video Clip
When is a mole not a mole? Section one of this program demystifies concepts such as Avogadro's Constant, molecular mass, and molar mass. In section two, the Percent Composition Formula is spotlighted, while section three addresses the Empirical Formu...(more details)
 
Properties of Solutions

If chemical terms like miscibility, concentration, and osmosis are a mystery, this program provides the solution. They and other key concepts-including solubility, saturation, dilution, and electrolytes; mass percentage composition, mole fractions, m...(more details)
 
Chemical Equations and Atomic and Molecular Mass
View Video Clip
Can a barbershop quartet introduce the subject of stoichiometry? They do in this program, which in section one presents the Law of Conservation of Mass and how to balance equations. Section two explains the difference between the mass number and atom...(more details)
 
Thermochemistry
