In this video, I explain why some reactions explode while others cool, exploring the root cause of chemical energy. I discuss the chemistry behind endothermic and exothermic reactions, which involves ...

Speaker one Have you ever had a bump or a sprain and needed a cold compress? Speaker two Yes, all the time. Now, some cold packs use a chemical reaction to absorb heat. This is an example of something ...

Support students with focused revision of GCSE Chemistry Energy Changes using this structured unit booklet. Covers essential concepts including exothermic and endothermic reactions, reaction profiles, ...

Iron oxide, aluminum, and a catalyst are placed in a flowerpot. The reaction is extremely exothermic resulting in molten iron and aluminum dripping into sand below the flowerpot. The demonstration ...

The dynamics of exothermic reactions in reactive multilayer systems hinge on the rapid, self-sustained release of heat as nanoscale layers of dissimilar materials intermix and form intermetallic ...
