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 ...

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 ...

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 ...

Singlet fission is a process whereby two triplet excitons can be produced from one photon, potentially increasing the efficiency of photovoltaic devices. Endothermic singlet fission is desired for a ...

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 ...

IS HELL EXOTHERMIC, OR ENDOTHERMIC?<br><br><br> The following is an actual question given on University of Liverpool<br> chemistry finals. The answer by one student was so "profound" that<br> the ...

Earlier this month I wrote about a new scientific paper that described an ancient, dinosaur-filled habitat that existed in what is now Siberia. Commenter Naruto raised a point of confusion to many; I ...
