Describes a demonstration of the decomposition of hydrogen peroxide to provide an interesting, quantitative illustration of the stoichiometric relationship between the decomposition of hydrogen peroxide and the formation of oxygen gas. This 10-minute demonstration uses ordinary hydrogen peroxide and yeast that can be purchased in a supermarket.…

Discusses a method to solve problems in stoichiometry which can also be applied to other problems involving relationships between constituents in a chemical reaction. Students with little prior knowledge of chemistry can successfully use the method. (Author/SK)

Describes an experiment involving the preparation of copper iodide that gives stoichiometric results. Materials needed and procedures are discussed along with ideas on different ways to analyze the data. Pertinent chemical equations are presented. (BC)

Presents four stoichiometric problems and their solutions that use spot metal prices quoted from the newspaper to integrate economics and chemistry. (MDH)

The outline for a unit on the chemistry of fitness and nutrition is presented. Topics discussed include the organic basis of life, functional groups, kitchen experiments, micronutrients, energetics, fitness vs. fatness, current topics, and evaluation. This unit reviews the basic concepts of chemical bonding, acid-base chemistry, stoichiometry, and…
