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 ...

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 ...

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 ...

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 ...
