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.
Oxidation States of Ions
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine the periodic table to identify metallic elements that have either fixed or variable oxidation states.
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.
Identifying Compounds and Ions
By Jill Larson
Learners complete an exercise to match chemical formulas with the names of binary compounds, tertiary compounds, and ions.
Product Yields in Chemical Reactions (Screencast)
Learners examine the meaning of theoretical yield, actual yield, and percent yield. They test their knowledge by solving two problems.
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.
Chemical Formulas
By Debbie McClinton, Dr. Martin McClinton
Students read an explanation of chemical formulas in this animated activity. A quiz completes the object.
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.
pH and Its Basic Principles
By Joan Kornitz
In this animated object, learners view hydrogen and hydroxide ions in a solution. A brief quiz on the basic principles of the term pH completes the activity.
