  2. Ammonium perchlorate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_perchlorate

    Mild heating results in production of hydrogen chloride, nitrogen, oxygen, and water. 4 NH 4 ClO 4 → 4 HCl + 2 N 2 + 5 O 2 + 6 H 2 O. The combustion of AP is quite complex and is widely studied. AP crystals decompose before melting, even though a thin liquid layer has been observed on crystal surfaces during high-pressure combustion processes ...

  3. Perchlorate - Wikipedia

    en.wikipedia.org/wiki/Perchlorate

    Perchlorate compounds oxidize organic compounds, especially when the mixture is heated. The explosive decomposition of ammonium perchlorate is catalyzed by metals and heat. [13] As perchlorate is a weak Lewis base (i.e., a weak electron pair donor) and a weak nucleophilic anion, it is also a very weakly coordinating anion. [13]

  4. Ammonium chlorate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_chlorate

    Ammonium chlorate is an inorganic compound with the formula NH 4 ClO 3.. It is obtained by neutralizing chloric acid with either ammonia or ammonium carbonate, or by precipitating barium, strontium or calcium chlorates with ammonium carbonate or ammonium sulfate, producing the respective carbonate or sulfate precipitate and an ammonium chlorate solution.

  5. Ammonium perchlorate composite propellant - Wikipedia

    en.wikipedia.org/wiki/Ammonium_perchlorate...

    Ammonium perchlorate composite propellant (APCP) is a solid rocket propellant.It differs from many traditional solid rocket propellants such as black powder or zinc-sulfur, not only in chemical composition and overall performance but also by being cast into shape, as opposed to powder pressing as with black powder.

  6. Heat of combustion - Wikipedia

    en.wikipedia.org/wiki/Heat_of_combustion

    For a fuel of composition C c H h O o N n, the (higher) heat of combustion is 419 kJ/mol × (c + 0.3 h − 0.5 o) usually to a good approximation (±3%), [2] [3] though it gives poor results for some compounds such as (gaseous) formaldehyde and carbon monoxide, and can be significantly off if o + n > c, such as for glycerine dinitrate, C 3 H 6 ...

  7. Ammonium chloride - Wikipedia

    en.wikipedia.org/wiki/Ammonium_chloride

    One of the innovations in Jabirian alchemy was the addition of ammonium chloride to the category of chemical substances known as 'spirits' (i.e., strongly volatile substances). This included both naturally occurring sal ammoniac and synthetic ammonium chloride produced from organic substances. The addition of sal ammoniac to the list of ...

    "The best thing you can do to protect yourself is to not travel if you can," AccuWeather Meteorologist Bernie Rayno said, but "if you do have to be out on the roads, you need to have a kit with ...

  9. List of thermal conductivities - Wikipedia

    en.wikipedia.org/wiki/List_of_thermal_conductivities

    In heat transfer, the thermal conductivity of a substance, k, is an intensive property that indicates its ability to conduct heat. For most materials, the amount of heat conducted varies (usually non-linearly) with temperature. [1] Thermal conductivity is often measured with laser flash analysis. Alternative measurements are also established.
