Molarity
By Jill Larson
Students solve a molarity problem in a drag and drop exercise.
Product Yields in Chemical Reactions (Screencast)
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine the meaning of theoretical yield, actual yield, and percent yield. They test their knowledge by solving two problems.
Solubility of Ionic Compounds in Water
By Dr. Miriam Douglass, Dr. Martin McClinton
Learners view movie clips to determine the solubility of two ionic compounds. They also examine a solubility chart and predict the solubility of compounds.
Ideal Gas Law
In this interactive object, learners use the ideal gas law to solve a practice problem.
The Combined Gas Law
Learners combine Boyle's Law and Charles's Law to solve for the pressure, volume, and temperature of a gas sample under two sets of conditions.
Equilibrium
By Jill Larson, Anne Peregrine
Equilibrium plays a vital role in our lives. We'll show you how the equilibrium formula works in real life using our friend the chicken.
Gas Volume and Molar Amount
By Dr. Miriam Douglass
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.
Identifying Compounds and Ions
Learners complete an exercise to match chemical formulas with the names of binary compounds, tertiary compounds, and ions.
Dilution of Hydrochloric Acid
In this interactive object, learners examine how to properly dilute hydrochloric acid.
Calculating Gas Density from Standard Molar Volume
Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.
