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 : EmpirFormulaFromRxn (10 Variations)

A substance is analyzed and found to contain 57.10% carbon, 4.80% hydrogen and 38.06% oxygen by weight. Its molecular weight is determined to be 126.11 g/mol. Which of the structures shown are possible structures for the substance?
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.

Linking Laboratory Experiences to the Real World: The Extraction of Octylphenoxyacetic Acid from WaterJorge E. Loyo-Rosales, Alba Torrents, Georgina C. Rosales-Rivera, and Clifford P. Rice A known quantity of the sodium salt of octylphenoxyacetic acid is dissolved in water, transformed to the acid (insoluble) form, and extracted using dichloromethane. These changes can be followed visually owing to conspicuous changes in solution turbidity. Loyo-Rosales, Jorge E.; Torrents, Alba; Rosales-Rivera, Georgina C.; Rice, Clifford P. J. Chem. Educ.2006, 83, 248.
