  2. Salt metathesis reaction - Wikipedia

    en.wikipedia.org/wiki/Salt_metathesis_reaction

    In older literature, the term double decomposition is common. The term double decomposition is more specifically used when at least one of the substances does not dissolve in the solvent , as the ligand or ion exchange takes place in the solid state of the reactant.

  3. Tricalcium phosphate - Wikipedia

    en.wikipedia.org/wiki/Tricalcium_phosphate

    Tricalcium phosphate is produced commercially by treating hydroxyapatite with phosphoric acid and slaked lime. [4]It cannot be precipitated directly from aqueous solution. Typically double decomposition reactions are employed, involving a soluble phosphate and calcium salts, e.g. (NH 4) 2 HPO 4 + Ca(NO 3

  4. Nickel organic acid salts - Wikipedia

    en.wikipedia.org/wiki/Nickel_organic_acid_salts

    Nickel terephthalate can be made by a double decomposition of sodium terephthalate and nickel nitrate. Nickel terephthalate precipitates. Its solubility is 0.38 g/100g water at 25 °C. In ammonium hydroxide a violet solution forms. Boiling acetic acid converts the nickel to nickel acetate.

  5. Cholesky decomposition - Wikipedia

    en.wikipedia.org/wiki/Cholesky_decomposition

    In linear algebra, the Cholesky decomposition or Cholesky factorization (pronounced / ʃ ə ˈ l ɛ s k i / shə-LES-kee) is a decomposition of a Hermitian, positive-definite matrix into the product of a lower triangular matrix and its conjugate transpose, which is useful for efficient numerical solutions, e.g., Monte Carlo simulations.

  6. Diamidophosphate - Wikipedia

    en.wikipedia.org/wiki/Diamidophosphate

    The silver salt AgPO 2 (NH 2) 2 can react using double decomposition with bromides forming other salts. The potassium dithiophosphate salt KPO 2 (NH 2) 2 is also known. Phosphorodiamidic acid crystallizes as a trihydrate. [4]

  7. Chemical decomposition - Wikipedia

    en.wikipedia.org/wiki/Chemical_decomposition

    Chemical decomposition, or chemical breakdown, is the process or effect of simplifying a single chemical entity (normal molecule, reaction intermediate, etc.) into two or more fragments. [1] Chemical decomposition is usually regarded and defined as the exact opposite of chemical synthesis. In short, the chemical reaction in which two or more ...

  8. Matrix decomposition - Wikipedia

    en.wikipedia.org/wiki/Matrix_decomposition

    Decomposition: This is a version of Schur decomposition where and only contain real numbers. One can always write A = V S V T {\displaystyle A=VSV^{\mathsf {T}}} where V is a real orthogonal matrix , V T {\displaystyle V^{\mathsf {T}}} is the transpose of V , and S is a block upper triangular matrix called the real Schur form .

  9. Single displacement reaction - Wikipedia

    en.wikipedia.org/wiki/Single_displacement_reaction

    A single-displacement reaction, also known as single replacement reaction or exchange reaction, is an archaic concept in chemistry.It describes the stoichiometry of some chemical reactions in which one element or ligand is replaced by atom or group.
