[Free Registration/Login may be required to access all resource tools.] Defines reactant, product, and chemical equation.

[Free Registration/Login Required] Drag the atoms from the table to create chemical formulas. You will need a sign-in to access this media, but it will be well worth your time!

In this activity, students explore reactions in which chemical bonds are formed and broken. Students experiment with changing the temperature and the concentration of the atoms in order to see how these affect reaction rates. They also...

In this limiting reagents problem, students are given specific concentrations of DNA solutions and are asked to predict what products and reactants will remain after a specific volumes are mixed and reaction has occurred.

Interactive calculator that allows you to input reactants and products of a reaction and calculate the change in enthalpy and Gibbs Free Energy for the reaction.

Learn about the equilibrium pressures of chemical reactions. Follow the general steps used in calculating the pressures, and see some examples. Also find links to tutorials, presentation, and animations about other chemistry topics.

An interactive simulation that teaches about chemical reactions and limiting reactants by creating sandwiches to represent chemical reactions. See how many can be made using different amounts of reactants. This simulation can either be...

A multiple-choice quiz on the processes of respiration and photosynthesis in plants.

[Free Registration/Login may be required to access all resource tools.] In this learning module, students will learn how to calculate and account for the amounts of reactants and products in a given chemical reaction.

You should be able to calculate the masses of reactants and products from balanced equations, and the formula of a compound from information about reacting masses.

Discover types of organic reactions. Explore by reactants and products. Use the interactive portion of this module to draw mechanisms associated with these reactions.

Explore the analogy of sandwich making with several ingredients and see if anything is left over. Then do the same thing with reactants in a chemical reaction, to see how many different products can be made. Afterwards, play a game with...

Watch this tutorial, and learn how to identify the limiting reactant in a chemical reaction. [7:04]

This lesson will define a limiting reactant and its significance as well as the term "in excess". It is 2 of 2 in the series titled "Limiting Reactant Definition."

[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.

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.

Students analyze the chemical equation for the reaction between vinegar and baking soda. They observe that the gas produced in the reaction is also part of the products of the written chemical equation.

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.

[Free Registration/Login may be required to access all resource tools.] Students explore mass relations between reactants and products for a given chemical process, and practice balancing chemical equations.

[Free Registration/Login may be required to access all resource tools.] How do trees help you breathe? This activity covers the connection between cellular respiration and photosynthesis and identifies the products and reactants of each.

In this lesson on exploring photosynthesis, students will explore photosynthesis by examining the reactants and products of this process.

Observe a visual representation of the equilibrium of products and reactants in chemical reactions. Record data while the reactions are taking place and print out a report afterwards.
