Learners examine a table of common polyatomic ions. Eight examples are provided for practice.
Gas Volume vs. Temperature (Charles's Law)
By Dr. Miriam Douglass, Dr. Martin McClinton
In this animated object, learners examine how gas volume varies directly with absolute temperature (K at constant pressure). An example of a sample of gas at two conditions of volume and temperature is used to illustrate the law.
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
In this well-illustrated activity, learners examine the three types of intermolecular forces: dipole-dipole forces, London or Van der Waals forces, and the hydrogen bond. Two interactive questions are included.
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.
Introduction to Safety in the Chemistry Lab
By Bruce Bell
Learners read about lab equipment and basic safety measures. In a quiz, they view photos and determine if the lab technicians pictured are using safe practices.
