In this animated activity, learners examine what gases are composed of and how their particles interact. They also consider several assumptions that form the basis for the Kinetic Theory of Gases.
Calculating Gas Density from Standard Molar Volume
By Dr. Miriam Douglass
Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.
Mole Ratios in Chemical Equations
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners use the coefficients in a balanced equation to develop the mole ratios of reactants and products involved in the reaction. Five interactive examples illustrate the method, and students test their knowledge by working four problems.
By Dr. Miriam Douglass, Dr. Martin McClinton
Learners view several movie clips that demonstrate the use of an indicator to follow the neutralization reaction that occurs when an acid and a base are mixed. Students test their knowledge in a series of questions. Immediate feedback is given.
