  2. Gas blending - Wikipedia

    en.wikipedia.org/wiki/Gas_blending

    Gas blending is the process of mixing gases for a specific purpose where the composition of the resulting mixture is defined, and therefore, controlled. A wide range of applications include scientific and industrial processes, food production and storage and breathing gases.

  3. Phosphoric acids and phosphates - Wikipedia

    en.wikipedia.org/wiki/Phosphoric_acids_and...

    The general formula of a phosphoric acid is H n−2x+2 P n O 3n−x+1, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure; that is, the minimum number of bonds that would have to be broken to eliminate all cycles.

  4. Phosphate - Wikipedia

    en.wikipedia.org/wiki/Phosphate

    The phosphate ion has a molar mass of 94.97 g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion [HPO 4 ] 2− , which in turn is the conjugate base of the dihydrogen phosphate ion [H 2 PO 4 ] − , which in turn is the conjugate ...

  5. Triphosphorus pentanitride - Wikipedia

    en.wikipedia.org/wiki/Triphosphorus_pentanitride

    As a fuel in pyrotechnic obscurant mixtures, it offers some benefits over the more commonly used red phosphorus, owing mainly to its higher chemical stability. Unlike red phosphorus, P 3 N 5 can be safely mixed with strong oxidizers, even potassium chlorate. While these mixtures can burn up to 200 times faster than state-of-the-art red ...

  6. Allotropes of phosphorus - Wikipedia

    en.wikipedia.org/wiki/Allotropes_of_phosphorus

    White phosphorus, yellow phosphorus or simply tetraphosphorus (P 4) exists as molecules of four phosphorus atoms in a tetrahedral structure, joined by six phosphorus—phosphorus single bonds. [1] The free P 4 molecule in the gas phase has a P-P bond length of r g = 2.1994(3) Å as was determined by gas electron diffraction . [ 2 ]

  7. Phosphorus - Wikipedia

    en.wikipedia.org/wiki/Phosphorus

    Phosphorus is an essential macromineral for plants, which is studied extensively in edaphology to understand plant uptake from soil systems. Phosphorus is a limiting factor in many ecosystems; that is, the scarcity of phosphorus limits the rate of organism growth.

  8. Organophosphorus chemistry - Wikipedia

    en.wikipedia.org/wiki/Organophosphorus_chemistry

    Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. [1] They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment.

  9. Phosphorus trichloride - Wikipedia

    en.wikipedia.org/wiki/Phosphorus_trichloride

    Phosphorus trichloride is an inorganic compound with the chemical formula PCl 3. A colorless liquid when pure, it is an important industrial chemical , being used for the manufacture of phosphites and other organophosphorus compounds .
