Because reactions can be considered "additive," a series of reactions can be written like simultaneous mathematical equations and a net reaction determined by addition. To use this simulation, select individual reactions from the three...

Through critical thinking, students realize that spontaneous events happen in a certain order. This lesson plan presents an examination of the Second Law of Thermodynamics using a thought story, rubber band inquiry, discrepant event and...

In this chemistry lab, learners investigate two types of reactions and answer questions relating to exothermic and endothermic reactions.

With an overview of topics related to chemical energetics, this site provides a foundation to a study of thermodynamics and calorimetry. Other topics covered include calorimeter constant, bomb calorimetry, and more.

This article from the Florida State University provides an excellent explanation of WHY Hess's Law works and examples of how to use the law. Common mistakes are identified and explained.

This resource provides information on a rather interesting spontaneous endothermic reaction, involving cobalt (II) chloride and thionyl chloride.

A nice juxtaposition of endo- and exothermic reactions. Outlines two demonstrations. Barium hydroxide, sodium acetate, ammonium nitrate, ammonia.

Simple description and demonstration to illustrate the concept of Heat of solution!

[Free Registration/Login Required] Sort the biological reactions into one of two groups based on the type of biochemical reactions represented.

Assess your ability to distinguish between exothermic and endothermic chemical reactions with this interactive multiple choice quiz. Receive immediate feedback to your answers.

Students work through this inquiry-based lab while observing and recording the heat processes taking place. The lab demonstrates exothermic and endothermic processes, and then challenges the students to predict the outcome of an unknown...

This lab allows young scholars to collect data for different types of reactions: endothermic and exothermic. Students compile the data, create graphs and answer questions concerning their lab experience.

Given scenarios, illustrations, or descriptions, students will identify the process of calorimetry and calculate the heat of a chemical process.

This physics tutorial covers the topic of measuring the quantity of heat that is transferred between the system and the surroundings. Students learn about calorimetry- the science associated with determining the changes in energy of a...

This page is a lab that will teach you about heating and cooling curves.

This lesson focuses on heat energy changes in chemical reactions. Exothermic reactions transfer energy to the surroundings. Endothermic reactions take in energy from the surroundings. It also offers links to a video and a test.

This chemistry e-textbook provides students with AP-level reading and practice material on thermochemistry.

Here are the lab instructions for a classic endothermic reaction. This is NOT a try-it-at-home experiment.

Explains the differences between endothermic and exothermic reactions and the role thermodynamic potentials play in them. Examples from nature are also provided.
