In this animated object, learners examine synthesis, decomposition, exchange, and reversible reactions.

Learners identify combination, decomposition, displacement, and combustion types of redox reactions. They also watch a video clip that demonstrates the reaction of sodium and water.

In this animated and interactive object, learners examine kinetic and potential energy as well as the first law of thermodynamics and the flow of energy between a system and its surroundings. Students also answer questions about exothermic and endothermic reactions

In this interactive object, learners determine the limiting reagent and the excess reagent in chemical reactions. Learners test their knowledge by solving three problems.

Learners examine the meaning of oxidation, reduction, and half-reaction, and watch a film showing the deposition of copper metal from the reduction of copper (II) ion by aluminum. A brief quiz completes the activity.

In this interactive and animated object, learners use solubility rules to predict when an insoluble ionic compound will precipitate in a double replacement reaction. Step-by-step examples are given.

Learners view several movie clips that demonstrate the use of an indicator to follow the neutralization reaction that occurs when an acid and a base are mixed. Students test their knowledge in a series of questions. Immediate feedback is given.

Learners examine the meaning of theoretical yield, actual yield, and percent yield. They test their knowledge by solving two problems.

In this interactive object, learners identify charges on ions, write new formulas based on charge, and balance equations using coefficients.

In this animated object, learners examine how the heating or cooling steps in a manufacturing process work to control a chemical reaction.

Learners review a graphic summary of the three series of reactions that occur during cellular respiration and the net energy (ATP) yield of that process.

Learners examine strategies for evaluating new ideas and accepting change. They consider a list of various reactions to change and a list of actions that enhance teamwork, and check those statements that apply to themselves.

Learners reflect on their thoughts, feelings, and reactions toward such listening behaviors as interrupting, selective listening, and unresponsive listening.

In this interactive object, learners calculate the amount of heat evolved or absorbed in chemical reactions. Four practice problems are provided.

In this animated activity, learners examine the terms "half-reaction," "oxidizing agent," and "reducing agent" and follow five interactive examples to balance equations for oxidation-reduction reactions. Three problems are provided as a self-check.
