A complete exothermic reaction demonstration with a chemical explanation. Using potassium permanganate and glycerol, Professor Mike Canestro will be performing a complete exothermic reaction ...

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 ...

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 ...

Students explore the concept that chemical reactions involve the breaking of bonds between atoms in the reactants, and the rearrangement and rebonding of these atoms to make the products. Students ...

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 ...
