If energy is released by a reaction, the reaction is exothermic. If energy is absorbed by a reaction, the reaction is endothermic. When petrol burns via a combustion reaction, energy released can be ...

A presenter-led science video investigating exothermic and endothermic reactions, with Dr Maggie Aderin-Pocock and Dr Alex Lathbridge.

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