2. Glycerol and potassium permanganate - Wikipedia

   en.wikipedia.org/wiki/Glycerol_and_potassium...

   The white smoke-like vapor produced by the reaction is a mixture of carbon dioxide gas and water vapor. Since the reaction is highly exothermic, initial sparking occurs, followed by a lilac- or pink-colored flame. [9] When energy or heat is added to electrons, their energy level increases to an excited state.

3. Exothermic process - Wikipedia

   en.wikipedia.org/wiki/Exothermic_process

   An example of an endothermic reaction is a first aid cold pack, in which the reaction of two chemicals, or dissolving of one in another, requires calories from the surroundings, and the reaction cools the pouch and surroundings by absorbing heat from them.

4. Water-reactive substances - Wikipedia

   en.wikipedia.org/wiki/Water-reactive_substances

   Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [3] Notable examples include alkali metals, lithium through caesium, and alkaline earth metals, magnesium through barium.

5. Cross-coupling reaction - Wikipedia

   Mechanism proposed for the Sonogashira coupling.. Catalysts are often based on palladium, which is frequently selected due to high functional group tolerance. Organopalladium compounds are generally stable towards water and air.

6. Nano-thermite - Wikipedia

   en.wikipedia.org/wiki/Nano-thermite

   This allows for high and customizable reaction rates. Nano-thermites contain an oxidizer and a reducing agent , which are intimately mixed on the nanometer scale. MICs, including nano-thermitic materials, are a type of reactive materials investigated for military use, as well as for general applications involving propellants, explosives, and ...

8. Flameless ration heater - Wikipedia

   en.wikipedia.org/wiki/Flameless_ration_heater

   The chemical reaction begins immediately, and takes about 12 to 15 minutes to heat a food pouch to about 60 °C (140 °F). It is recommended to place the bag within the cardboard carton the MRE is issued with to prevent injury, and to prop it upright so the water does not leak out and prematurely stop the reaction. [3]
