Learners examine how melting, vaporization, and sublimation require energy input while freezing and condensation release energy.
Energy in Chemical Reactions
By Dr. Miriam Douglass
In this animated and interactive object, learners examine kinetic and potential energy as well as the first law of thermodynamics and the flow of energy between a system and its surroundings. Students also answer questions about exothermic and endothermic reactions
Gas Volume and Molar Amount
In this brief object, learners examine the direct relationship between the volume of a gas sample and the number of moles of gas. A problem is presented so students can test their knowledge of Avogadro's Law.
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.
