When a chemical reaction occurs, energy is transferred to or from the surroundings. There is usually a temperature change. For example, when a bonfire burns it transfers heat energy to the ...

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

Do not attempt to perform this demonstration. The combustion of methane is an example of an exothermic reaction. More energy is released when the bonds in the products are formed than is used to break ...
