Chemical Reax/exothermic Reactions

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...

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...

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...

Have you ever pulled a muscle or just been sore after a long day of work or exercise? Hot showers are great, but maybe you've used the more convenient heat packs. Heat packs, which you can buy at grocery or drug stores to soothe aching...

Students will observe an exothermic reaction in this activity where they add calcium chloride to a baking soda solution. This increase in temperature is due to the chemical change that has occurred.

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. 

Using an illustrated example, the difference between an endothermic and an exothermic reaction is described. The concept of enthalpy, or heat energy change, is explained, and the energy diagrams of reactions are presented.

In this instructional activity on endothermic and exothermic reactions, students explore chemical reactions, energy transfer, and energy diagrams.
