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

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...

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...

Explains the essence of limiting reactant problems using a sample problem: How can an amount of product (KNO3) be predicted from amounts for two reactants (KCl and HNO3)? Shows the work and explains how to solve these types of problems.

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...

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...

[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....

Perform virtual lab experiments safely. Pour and mix specific amounts of various solutions on screen and observe changes in temperature and pH. Choose glassware and other tools (ie. bunsen burner, scale) to assist with virtual lab...

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

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...

An experiment to extract DNA from green split peas, spinach, chicken liver, strawberries, and broccoli using simple household reagents.

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

Investigate different methods for testing the sugar content in foods, and determine relative amounts of sugar in several juices using a sugar indicator solution.

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.

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.

Read the passage Hair Dye Chemicals and Cancer and answer the five-question quiz that follows.

A site discussing chemical reactions in chemistry including reaction rate, types of reactions, reagents, reactants, catalysts, and inhibitors.

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.

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

What is a chemical reaction? Learn about chemical equations, the four types of chemical reactions, and other fun facts.
