The Stoichiometry group contains three groups: Exploding Soap Bubbles: Hydrogen + Oxygen; Acid-Base Titrations and Animation; and Redox Titration and Animation.
Gas Stoichiometry  
Gas is generated from one mole of liquid of solid and the volume is measured using a gas collection system.

Atoms,_Molecules_and_Ions : MassInAlloy (10 Variations)
Gold is alloyed with other metals to make it less malleable. 10 karat gold is an alloy that is 41.7% gold. How much pure gold is in a 20. gram 10 karat gold ring?
Stoichiometry : GramMoleProblem (9 Variations)
Which sample contains the largest number of nitrogen atoms?
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?

Trial AgOCN used NH4Cl AgCl produced
1 20.4 mL 5.3 mL 2.4 g
2 20.3 mL 10.4 mL 4.3 g
3 20.6 mL 15.4 mL 6.2 g
4 20.5 mL 20.6 mL 8.2 g
5 20.4 mL 25.2 mL 10.2 g
6 20.3 mL 30.4 mL 10.3 g

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.)

Ionic Blocks  Richard S. Sevcik, Rex Gamble, Elizabet Martinez, Linda D. Schultz, and Susan V. Alexander
"Ionic Blocks" is a teaching tool designed to help middle school students visualize the concepts of ions, ionic compounds, and stoichiometry. It can also assist high school students in reviewing their subject mastery.

Determination of the Formula of a Hydrate: A Greener Alternative  Marc 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.
