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 : FormulaFromComp (8 Variations)
Lactic acid is the substance that makes your muscles burn when you've been exercising hard. Lactic acid is composed of 40.0% carbon, 6.7% hydrogen, and 53.3% oxygen by weight. If it has a molar mass of 90 g/mol, what is its molecular formula?
Determination of the Formula of a Hydrate: A Greener AlternativeMarc A. Klingshirn, Allison F. Wyatt, Robert M. Hanson, and Gary O. Spessard This article describes how the principles of green chemistry were applied to a first-semester, general chemistry courses, specifically in relation to the determination of the formula of a copper hydrate salt that changes color when dehydrated and is easily rehydrated with steam. Klingshirn, Marc A.; Wyatt, Allison F.; Hanson, Robert M.; Spessard, Gary O. J. Chem. Educ.2008, 85, 819.

Concept Maps for General Chemistry Boyd L. Earl Two concept maps have been developed to represent the organization of the material in a first-semester general chemistry course. By providing these maps to students and referring to them in class, it is hoped that the instructor can assist students in maintaining a grasp of the "big picture" during the progress of the course. Earl, Boyd L. J. Chem. Educ.2007, 84, 1788.
