In this limiting reagents problem, students mix together solutions in different ratios in an attempt to produce a final solution that contains only 1 product.

In this advanced limiting reagent problem, students use the virtual lab to determine the concentration of a solution of DNA by reacting it with known amounts of a fluorescent dye which binds to the DNA.

This is a complete course in chemical stoichiometry, set in a scenario that shows how stoichiometry calculations are used in real-world situations. This course has been designed to not only help you strengthen your skills with...

One of the first numerical problems encountered in introductory chemistry is that of "limiting reagents". This applet serves as a supplement to such calculations, providing imagery that helps students see beyond the rote mathematics.

Find out the procedure in determining the theoretical yield of a product in a chemical reaction. [6:25]

Resource provides notes on Moles and Stoichiometry. Deals with all book-keeping aspects, including as section on yields and limiting reactants. Includes lesson plans, lecture slides and notes, links to related websites, and frequently...

Students will use manipulatives that represent the ingredients for S'mores (graham crackers, marshmallows, chocolate bar) to determine the limiting and excess reactants (reagents) for making S'mores. The students will extend this to...

[Free Registration/Login may be required to access all resource tools.] Students will compare theoretical yield to actual yield, and then investigate what happens when one reactant runs out before the other reactants are fully consumed....

A chemistry lab where young scholars investigate limiting reagents and balanced chemical equations. A simple experiment that gives students a physical example of what limiting reactant means.

Great analogy if you are uncomfortable with the concept of limiting reactants. A great starting point. Finishes with chemistry.

[Free Registration/Login Required] Using atoms from a reactants pool, construct products of an equation shown and place them in the product pool. Then answer a challenge question about the topic.

Students use the virtual lab to determine how four unknown substances react with each other including their stoichiometric coefficients. In this randomized activity, each student receives a different reaction and students can check their...

Set in the context of ground water contamination in Bangladesh, this stoichiometry and analytical chemistry activity examines the issues around identifying wells contaminated with arsenic. In this activity, students perform a gravimetric...

Slide show focusing on the elements of stoichiometry relating to limiting reactants. Go through the first several slides to review or introduce the topic.

This applet is similar to the stoichiometry simulation but applies to chemical reactions that do not go to completion. The calculation of the equilibrium state of such reactions is typically covered months after students learn how to...

Participate in the investigation of a virtual crime scene using chemistry concepts to solve a mysterious death. The 40-50 minute activity can be used as a classroom lab or as a homework assignment. Additionally, teachers may request a...

A collection of over 30 virtual chemistry problems with accompanying interactive activities. Each problem includes a word file for potential differentiation in your classroom.

Frostburg State University provides an example of a problem dealing with how to find expected yield. Includes step-by-step directions on how to solve the problem.

Explains vocabulary used when talking about the yield of a chemical reaction and models how to calculate the theoretical and the percentage yield in an example problem.

Definition of precipitation gravimetry, and an example of using precipitation gravimetry to determine the purity of a mixture containing two salts.
