Limiting and Excess Reagents

For this chemical reaction worksheet, students determine the limiting reactant in the equations given plus determine the amount of moles of product produced. This worksheet has 6 problems to solve.

In this stoichiometry worksheet, students write in the definition for the 6 terms associated with stoichiometry including actual yield, percent yield, and limiting reactant.

In this chemical equation worksheet, students determine the limiting reactant and the excess reactant for the given reactions. This worksheet has 10 problems to solve.

Four balanced chemical equations are presented for your pupils to analyze. They identify limiting reagents and use dimensional analysis to compute products. This practical worksheet is one that you will want to keep in your repertoire to...

Junior chemists discover how to calculate excess reactants, handle limiting reactants, and determine percent yield. After background information is provided, step-by-step examples are solved. You can use this detailed slide show to teach...

Chemistry classes learn the importance of a limiting reactant by first considering a cake recipe. Given the recipe and the total amount available for each ingredient, they must calculate how many cakes can be made. Finally, they apply...

An installment from the Socratica chemistry video series explains limiting reactants. It includes multiple example problems to demonstrate how scientists control for these limiting reagents.

Viewers watch while the narrator explains limiting reactions through the familiar example of a recipe. He then describes why it is necessary to use moles to solve these problems rather than just relying on diagrams. The video ends...

Build a solid understanding of reactants used and products produced in a chemical reaction with a lesson that begins with a basic stoichiometry problem and advances to questions involving limiting reactants and percent yields. 

In this limiting reactant worksheet, students solve four problems to identify the theoretical yield and percent yield given an equation. They also calculate the limiting reactant.
