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 : CalcPercentYield (8 Variations)
When copper is heated in air, copper(II) oxide is formed. In a given experiment, 1.50 g copper was heated to yield 1.76 g copper(II) oxide. What is the percent yield?
Cross-Proportions: A Conceptual Method for Developing Quantitative Problem-Solving SkillsElzbieta Cook and Robert L. Cook This paper focuses attention on the cross-proportion (C-P) method of mathematical problem solving, which was once widely used in chemical calculations. We propose that this method regain currency as an alternative to the dimensional analysis (DA) method, particularly in lower-level chemistry courses. In recent years, the DA method has emerged as the only problem solving mechanism offered to high-school and general chemistry students in contemporary textbooks, replacing more conceptual methods, C-P included.
