In this interactive and animated object, learners use solubility rules to predict when an insoluble ionic compound will precipitate in a double replacement reaction. Step-by-step examples are given.
Types of Elements in the Periodic Table and Their Properties (Screencast)
By Debbie McClinton, Dr. Martin McClinton
In this screencast, we review the positions of metals, metalloids, and nonmetals in the Periodic Table and the general characteristics of each.
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.
Calculation of Atomic Weight from Isotopic Composition
By Debbie McClinton, Dr. Miriam Douglass, Dr. Martin McClinton
Learners examine the method for calculating the atomic weight of copper from the natural percent composition of each of its two isotopes.
Double Replacement Reactions
By Jill Larson
In this interactive object, learners identify charges on ions, write new formulas based on charge, and balance equations using coefficients.
