These systems are characterized by alternating layers of reactive materials that can undergo exothermic reactions, releasing substantial amounts of heat. This heat can be harnessed for various ...

All chemical reactions involve an energy change. We categorise reactions by the direction of this energy change. If energy is released by a reaction, the reaction is exothermic. If energy is absorbed ...

The slideshow describes an exothermic reaction between dilute sodium hydroxide and hydrochloric acid, and an endothermic reaction between sodium carbonate and ethanoic acid.

This video is about what exothermic and endothermic reactions are and how temperature changes can be used to identify which reaction is which. Exothermic reactions, in solution, give out energy ...
