Students read an explanation of chemical formulas in this animated activity. A quiz completes the object.
The Combined Gas Law
By Dr. Miriam Douglass, Dr. Martin McClinton
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.
Heat of Fusion and Heat of Vaporization
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine graphs and read that the heat of fusion is the heat energy absorbed by one mole of solid as it is converted to liquid, while the heat of vaporization is the heat energy absorbed by one mole of liquid as it is converted to gas.
Naming Binary Ionic Compounds Containing Variable Oxidation State Cations
Roman numerals are used to identify the charges on metal cations having multiple oxidation states. Five examples are provided for practice.
In this animated activity, learners compare the van der Waals equation with the Ideal Gas Law.
The Peptide Bond
By Eileen Bouchard
In this animated object, learners examine the properties of the peptide bond and how the bond relates to the structure of hair.
Methods of Producing Electricity
By Terry Bartelt
In this learning activity you'll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
Changes in Our World: Chemical and Physical
By Laurie Jarvis, Deb Simonson
In this animated object, learners examine the kinds of physical and chemical changes that occur in substances. They practice identifying examples of each.
The Disulfide Bond
In this animated lesson, learners read about the disulfide bond, the second strongest chemical bond in the hair. This bond can only be altered by chemicals.
Endothermic vs. Exothermic Reactions
In this animated object, learners examine how the heating or cooling steps in a manufacturing process work to control a chemical reaction.
