Students solve a molarity problem in a drag and drop exercise.
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.
Oxidation States of Ions
Learners examine the periodic table to identify metallic elements that have either fixed or variable oxidation states.
Biomolecules: The Carbohydrates (Video)
By Becky Polk-Pohlman
Viewers watch an introduction to monosaccharides, disaccharides, and polysaccharides. The processes for dehydration synthesis and hydrolysis.
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.
