Exothermic Reactions

How can you tell the difference between endothermic and exothermic reactions? Chemistry scholars perform and observe two chemical reactions, measure the temperature throughout, then draw conclusions about changes in energy from their...

Equip your chemistry class with the tools to properly understand endothermic and exothermic reactions. Young chemists collect, analyze, and graph data to determine how the Law of Conservation of Matter is applied to chemical composition...

Start this series of lessons with a bang! Five exothermic reactions are outlined in this resource, including a demonstration that produces both light and sound. In the lab, chemistry apprentices record temperature changes, make hand...

Chemistry whizzes test the change in water temperature produced by a burning candle and the change in acid temperature produced by magnesium metal. With these two laboratory activities they explore heat produced during chemical...

A total of five experiments lead chemistry pros to understand the difference between physical and chemical change. They also experiment with exothermic reaction factors that affect rate of reaction. The procedures are not written in the...

For advanced chemists, this worksheet examines heat change during chemcial reactions. Alkanes are examined first. Learners calculate the energy released or needed during a reaction.

What is required to get a chemical reaction? Chemistry learners find out by viewing this slide show. They will be able to compare endothermic and exothermic reactions, as well as draw energy level diagrams for each. A lab activity is...

The details here give definitions about chemical reactions and the energy transfer in those reactions. The reactions given include general examples of catalysts, inhibitors, and other situations that affect the rate of production and...

Investigate the properties of endothermic and exothermic reactions with a detailed video lesson that defines exothermic and endothermic. The instructor explains the properties of each reaction and gives several examples of each. 

Get a positive reaction from your class as they explore the energy of reactions through a video analysis. The second lesson in a series of 35 explains energy absorption and release during chemical reactions. Graphs track the energy to...
