Stoichiometry
Gas Stoichiometry Gas is generated from one mole of liquid of solid and the volume is measured using a gas collection system.
Stoichiometry : StoicNeeds (10 Variations) You have a known mass of a compound X and react it to form compound Y. What is the minimum information you need to find the mass of Y produced?
Ionic BlocksRichard S. Sevcik, Rex Gamble, Elizabet Martinez, Linda D. Schultz, and Susan V. Alexander "Ionic Blocks" is a teaching tool designed to help middle school students visualize the concepts of ions, ionic compounds, and stoichiometry. It can also assist high school students in reviewing their subject mastery. Sevcik, Richard S.; Gamble, Rex; Martinez, Elizabet; Schultz, Linda D.; Alexander, Susan V. J. Chem. Educ.2008, 85, 1631.

Stoichiometry
A Dramatic Classroom Demonstration of Limiting Reagent Using the Vinegar and Sodium Hydrogen Carbonate ReactionRomklao Artdej and Tienthong Thongpanchang This demonstration, appropriate for high school chemistry level and recommended for a large classroom presentation, is designed to illustrate the concept of limiting reagent via a series of experiments in which increasing amounts of sodium bicarbonate are added to a fixed amount of vinegar is fixed until the volume of carbon dioxide generated remains constant. Artdej, Romklao; Thongpanchang, Tienthong. J. Chem. Educ.2008, 85, 1382.

Stoichiometry
Oven versus Bunsen Burner When Heating Copper(II) Chloride DihydrateMichael C. Wirtz In "greening up" the classical stoichiometry experiment where students determine the formula of copper(II) chloride dihydrate, it is critical that teachers and instructors use a 110°C oven rather than a Bunsen burner. Copper(II) chloride dihydrate decomposes at temperatures above 300°C, releasing chlorine gas. Wirtz, Michael C. J. Chem. Educ.2008, 85, 1345.
