Explore the world of the Mole and discover information on the physical characteristics, habitat, diet, and breeding of this small mammal. Includes images and statistics.

As part of the "Basic Atomics" section of the Virtual Textbook, this site examines moles. The information presented defines moles in relation to Avogadro's number and then goes on to describe molar mass and molar volume.

Coast Moles are difficult to distinguish from Townsend's Moles where their ranges overlap in the Pacific Northwest. Both have velvety, dark-gray fur and tiny eyes and ears that are hidden under their fur. Learn more about the Scapanus...

The largest moles in North America, weighing in at 100 - 171 grams, Townsend's Moles live only in the lowlands on the western side of the Cascade Mountains, from northwestern California to extreme southwestern British Columbia. One...

A section in a college textbook exploring the ideal gas law in relation to molecules and in terms of moles. Learn how to calculate the variables in the ideal gas law. Also become familiar with Avogadro's number and how to use it to...

[Free Registration/Login may be required to access all resource tools.] Based on the balanced chemical equation, students will calculate the masses or moles of reactants or products generated in a given reaction. They will also convert...

This site deals with Amedeo Avogadro, his life, his contributions to chemistry, and his famous number.

A lengthy page covering most all the gas laws. Each law is described in words and stated as an equation. The use of each law in solving problems is demonstrated. Some problem-solving tips are provided. There are 23 practice problems with...

Explains the essence of limiting reactant problems using a sample problem: How can an amount of product (KNO3) be predicted from amounts for two reactants (KCl and HNO3)? Shows the work and explains how to solve these types of problems.

[Free Registration/Login may be required to access all resource tools.] Students write the solubility product constant expressions for nearly insoluble ionic compounds and perform calculations for compounds and solubility.

This site features a variety of live animal cams including cams of the lions, the giant pandas, and the elephants. In addition to the live cams, information on each animal is provided.

Students have the opportunity to study examples and worked out example problems to further their understanding of chemical solution concentration.

Read interesting facts on the Spotted Salamander including information on its physical characteristics, habitat (with a distribution map), diet, breeding patterns, unique traits and behavior, conservation status, and tips on what you can...

Learn about the life and work of Amedeo Avogadro, who was most noted for his contribution to molecular theory now known as Avogadro's law.

Learn why the Sun keeps us healthy, and also, learn how the Sun can harm our skin, eyes, and immune system. Read about the dangers associated with the Sun's ultraviolet rays, and read tips to help you stay safe when outside in the summer...

Understand volume-volume stoichiometry with these volume-based example problems worked with solutions and explanations.

This digital textbook covers core chemistry concepts and includes interactive features, real-world examples, and videos.

Because atoms are neither created nor destroyed in a chemical reaction, the total mass of products in a reaction must be the same as the total mass of the reactants.

Students will participate in a guided inquiry activity using manipulatives to learn how to balance chemical reactions. This activity was developed in cooperation with Michelle Holdbrooks at Thompson High School...

Explains vocabulary used when talking about the yield of a chemical reaction and models how to calculate the theoretical and the percentage yield in an example problem.
