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.
A Laboratory Experiment Using Molecular Models for an Introductory Chemistry ClassShahrokh Ghaffari Presents a new approach to using molecular models in teaching general chemistry concepts. Students construct molecular models and use them to balance simple chemical equations, demonstrate the law of conservation of mass, and discover the relationship between the mole and molecules and atoms. Ghaffari, Shahrokh. J. Chem. Educ.2006, 83, 1182.

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.

Procedure for Decomposing a Redox Reaction into Half-ReactionsIlie Fishtik and Ladislav H. Berka The principle of stoichiometric uniqueness provides a simple algorithm to check whether a simple redox reaction may be uniquely decomposed into half-reactions in a single way. For complex redox reactions the approach permits a complete enumeration of a finite and unique number of ways a redox reaction may be decomposed into half-reactions. Several examples are given.
