  2. Chemical decomposition - Wikipedia

    en.wikipedia.org/wiki/Chemical_decomposition

    An example of a spontaneous (without addition of an external energy source) decomposition is that of hydrogen peroxide which slowly decomposes into water and oxygen (see video at right): 2 H 2 O 2 → 2 H 2 O + O 2. This reaction is one of the exceptions to the endothermic nature of decomposition reactions.

  3. Hydrogen peroxide - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_peroxide

    Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue [5] liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (3%–6% by weight) in water for consumer use and in higher concentrations for industrial use.

  4. Elephant's toothpaste - Wikipedia

    en.wikipedia.org/wiki/Elephant's_toothpaste

    Hydrogen peroxide breaks down into oxygen and water. As a small amount of hydrogen peroxide generates a large volume of oxygen, the oxygen quickly pushes out of the container. [6] The soapy water traps the oxygen, creating bubbles, and turns into foam. [6] About 5-10 drops of food coloring could also be added before the catalyst to dramatize ...

  5. Supercritical water oxidation - Wikipedia

    en.wikipedia.org/wiki/Supercritical_water_oxidation

    Hydrogen peroxide was used as an oxidizing agent, and Eric Croiset was tasked with detailed measurements of the decomposition of hydrogen peroxide at supercritical water conditions. [ 6 ] In mid-1992, Thomas G. McGuinness, PE invented what is now known as the "transpiring-wall SCWO reactor" (TWR) while seconded to Los Alamos National Laboratory ...

  6. Catalase - Wikipedia

    en.wikipedia.org/wiki/Catalase

    Hydrogen peroxide is a harmful byproduct of many normal metabolic processes; to prevent damage to cells and tissues, it must be quickly converted into other, less dangerous substances. To this end, catalase is frequently used by cells to rapidly catalyze the decomposition of hydrogen peroxide into less-reactive gaseous oxygen and water ...

  7. Peroxide - Wikipedia

    en.wikipedia.org/wiki/Peroxide

    The peroxide group is marked in blue. R, R 1 and R 2 mark hydrocarbon moieties. The most common peroxide is hydrogen peroxide (H 2 O 2), colloquially known simply as "peroxide". It is marketed as solutions in water at various concentrations. Many organic peroxides are known as well. In addition to hydrogen peroxide, some other major classes of ...

  8. Chemical process of decomposition - Wikipedia

    en.wikipedia.org/wiki/Chemical_process_of...

    The human body is composed of approximately: 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. [1] The decomposition of soft tissue is characterized by the breakdown of these macromolecules, and thus a large proportion of the decomposition products should reflect the amount of protein and fat content initially present in the body. [4]

  9. Piranha solution - Wikipedia

    en.wikipedia.org/wiki/Piranha_solution

    The solution may be mixed before application or directly applied to the material, applying the sulfuric acid first, followed by the peroxide. Due to the self-decomposition of hydrogen peroxide, piranha solution should always be used freshly prepared (extemporaneous preparation).
