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.)

High School Chemistry Content Background of Introductory College Chemistry Students and Its Association with College Chemistry Grades  Robert H. Tai, R. Bruce Ward, and Philip M. Sadler
Do students who focus on some content areas in high school chemistry have an advantage over others in college chemistry? This manuscript seeks to answer this question through the use of a survey of 3521 introductory college chemistry students. The results indicate that studying stoichiometry in high school was most strongly predictive of college chemistry success.

A Simple and Easy-To-Learn Chart of the Main Classes of Inorganic Compounds and Their Acid–Base Reactions  Grigoriy Sereda
Presents a two-dimensional chart for the classification of the main classes of inorganic compounds with respect to their acidic and basic properties that makes it possible to predict reaction products and determine the coefficients in chemical equations of acidbase reactions.

Assessing the Effect of Web-Based Learning Tools on Student Understanding of Stoichiometry Using Knowledge Space Theory  Ramesh D. Arasasingham, Mare Taagepera, Frank Potter, Ingrid Martorell, and Stacy Lonjers
This paper reports a comparative study using knowledge space theory (KST) to assess the impact of a Web-based instructional software program on students' understanding of the concept of stoichiometry. The software program called Mastering Chemistry Web (MCWeb) allows students to practice problems that emphasize the development of molecular-level conceptualization and visualization, analytical reasoning, and proportional reasoning, as well as learning to recognize and relate different representations in chemistry. The experimental design compared students in two sections taught by the same instructor. One section used the MCWeb instructional software as homework (MCWeb group) while the other section used text-based homework (non-MCWeb group, control).
