Stoichiometry The Stoichiometry group contains three groups: Exploding Soap Bubbles: Hydrogen + Oxygen; Acid-Base Titrations and Animation; and Redox Titration and Animation.
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?
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.

Thermochemical Analysis of Neutralization Reactions: An Introductory Discovery ExperimentKenneth V. Mills and Louise W. Guilmette Describes a guided-inquiry laboratory pedagogy in which students discover chemical concepts in the lab and the instructor uses their pooled data to guide the lecture portion of the course. This method is illustrated by an experiment that reinforces students' understanding of stoichiometry and allows them to discover neutralization reactions and thermochemistry. Mills, Kenneth V.; Guilmette, Louise W. J. Chem. Educ.2007, 84, 326.

Interactive Demonstrations for Mole Ratios and Limiting ReagentsCrystal Wood and Bryan Breyfogle The objective of this study was to develop interactive lecture demonstrations based on conceptual-change learning theory. Experimental instruction was designed for an introductory chemistry course for nonmajors to address misconceptions related to mole ratios and limiting reagents Wood, Crystal; Breyfogle, Bryan. J. Chem. Educ.2006, 83, 741.
