In a combustion reaction, fuel is burned and reacts with oxygen to release energy. Respiration is the chemical change that takes place inside living cells. Glucose and oxygen are used to release ...

Usually, mechanochemical reactions between solid phases are either gradual (by deformation-induced mixing), or self-propagating (by exothermic chemical reaction). Here, by means of a systematic ...

To make a safe, portable form of heating to take to the rest of the team working up on the glacier. All combustion reactions (such as the burning of coal) are exothermic. Incredibly, the reaction ...

This topic explores the difference between endothermic and exothermic reactions in chemistry. Chemical reactions encompass a variety of processes categorised into subgroups, including endothermic and ...

Commercial heat packs (containing iron and water, or supersaturated sodium acetate) and cold packs (various ammonium salts) can be used to show exo- and endothermicity. Heat packs that contain iron ...

There probably aren’t many people out there who aren’t aware of what thermite is and how it demonstrates the power of runaway exothermic reactions. Practical applications that don’t involve destroying ...

Thermites are a double-edged sword. Packing a tremendous energy density, and eager to produce tremendous heat when ignited, thermite is great for welding train tracks. But sometimes you might be ...
