Learners examine the meaning of theoretical yield, actual yield, and percent yield. They test their knowledge by solving two problems.
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
The Limiting Reagent in Chemical Reactions
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
In this interactive object, learners determine the limiting reagent and the excess reagent in chemical reactions. Learners test their knowledge by solving three problems.
Standard Molar Volume
Learners observe that the volume of one mole of any gas is 22.4 L at standard temperature and pressure. An illustration shows that only the mass of the molar volume differs with the identity of the gas.
By Jill Larson
In this interactive object, students examine how the volume and temperature of an ideal gas relate under conditions of constant pressure and quantity.
