  2. Aluminium nitrate - Wikipedia

    en.wikipedia.org/wiki/Aluminium_nitrate

    More conveniently, the salt can be made by reacting nitric acid with aluminium hydroxide. Aluminium nitrate may also be prepared a metathesis reaction between aluminium sulfate and a nitrate salt with a suitable cation such as barium, strontium, calcium, silver, or lead. e.g. Al 2 (SO 4) 3 + 3 Ba(NO 3) 22 Al(NO 3) 3 + 3 BaSO 4.

  3. Tris(8-hydroxyquinolinato)aluminium - Wikipedia

    en.wikipedia.org/wiki/Tris(8-hydroxyquinolinato...

    Tris (8-hydroxyquinolinato)aluminium is the chemical compound with the formula Al (C 9 H 6 NO) 3. Widely abbreviated Alq 3, it is a coordination complex wherein aluminium is bonded in a bidentate manner to the conjugate base of three 8-hydroxyquinoline ligands.

  4. Standard enthalpy of formation - Wikipedia

    en.wikipedia.org/wiki/Standard_enthalpy_of_formation

    In chemistry and thermodynamics, the standard enthalpy of formation or standard heat of formation of a compound is the change of enthalpy during the formation of 1 mole of the substance from its constituent elements in their reference state, with all substances in their standard states. The standard pressure value p⦵ = 105 Pa (= 100 kPa = 1 ...

    2 KNO 3 + 5 Mg → K 2 O + N 2 + 5 MgO. The composition is 62.4% KNO 3 : 37.6% Mg by weight for the reactants of the above stoichiometrically balanced equation. Below is the same reaction but involving barium nitrate. Ba(NO 3) 2 + 5 Mg → BaO + N 2 + 5 MgO. Mixtures designed to make reports are substantially different from mixtures designed ...

  6. Hall–Héroult process - Wikipedia

    en.wikipedia.org/wiki/Hall–Héroult_process

    The Hall–Héroult process is the major industrial process for smelting aluminium. It involves dissolving aluminium oxide (alumina) (obtained most often from bauxite, aluminium 's chief ore, through the Bayer process) in molten cryolite and electrolyzing the molten salt bath, typically in a purpose-built cell. The Hall–Héroult process ...

  7. Oxygen balance - Wikipedia

    en.wikipedia.org/wiki/Oxygen_balance

    Oxygen balance (OB, OB%, or Ω) is an expression that is used to indicate the degree to which an explosive can be oxidized, [1] to determine if an explosive molecule contains enough oxygen to fully oxidize the other atoms in the explosive. For example, fully oxidized carbon forms carbon dioxide, hydrogen forms water, sulfur forms sulfur dioxide ...

  8. Limiting reagent - Wikipedia

    en.wikipedia.org/wiki/Limiting_reagent

    If in fact 18 mol O 2 are present, there will be an excess of (18 - 11.25) = 6.75 mol of unreacted oxygen when all the benzene is consumed. Benzene is then the limiting reagent. This conclusion can be verified by comparing the mole ratio of O 2 and C 6 H 6 required by the balanced equation with the mole ratio actually present:

  9. Thermometric titration - Wikipedia

    en.wikipedia.org/wiki/Thermometric_titration

    The reaction of silver nitrate with chloride is strongly exothermic. For instance, the reaction enthalpy of Ag + with Cl − is a high −61.2 kJ/mol. This permits convenient determination of chloride with commonly available standard 0.1 mol/L AgNO 3. Endpoints are very sharp, and with care, chloride concentrations down to 15 mg/L can be analyzed.
