In this video, the chemistry behind endothermic and exothermic reactions is explored through the lens of quantum physics. When molecules react, bonds between atoms break and new ones form; breaking ...

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 ...

The questions in this quiz are suitable for GCSE combined science students studying reactions and temperature changes, reaction profiles, and explaining energy changes. If you struggled with the quiz, ...

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 ...
