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 : LimitingReagent (8 Variations) The synthesis of urea by Frederich W??hler in 1825 began the decline of the idea that "organic" chemicals could only be made by living organisms as part of their biological processes.
AgOCN(aq) + NH4Cl(aq)AgCl(s) + NH2CONH2(aq)
If you perform this reaction and collect the following table of data, in which trial(s) is AgOCN clearly the limiting reactant?

The mL of AgOCN and NH4Cl are the initial amounts used, the mass of AgCl is how much was recovered from the reaction. (Hint: You do not need to do any calculations to answer this question.)
When A + B B + AErling Antony, Lindsay Mitchell, and Lauren Nettenstrom Many acid-base chemistry demonstrations and laboratory manuals include the "baking soda volcano". Others use the formation of calcium carbonate from calcium hydroxide and carbon dioxide in human breath. This demonstration uses principles from both as well as stoichiometry to answer the question "Does the order of mixing of reagents make a difference?"

The Synthesis, Characterization, and Lewis Acidity of SnI2 and SnI4Richard W. Schaeffer, Benny Chan, Michael Molinaro, Susan Morissey, Claude H. Yoder, Carolyn S. Yoder, and Stephanie Shenk In this project the student has the opportunity to learn about: a) the direct synthesis of compounds from the elements, b) stoichiometry and limiting reagent, c) isolation by recrystallization, d) use of inert atmosphere, e) identification by melting point, gravimetric analysis, powder x-ray diffraction, and NMR spectroscopy, and f) at least one method for determination of relative Lewis acidity.
