  2. Ammonia - Wikipedia

    en.wikipedia.org/wiki/Ammonia

    H2NCH2CH2OH → NH3 + CH3CHO. Ammonia is both a metabolic waste and a metabolic input throughout the biosphere. It is an important source of nitrogen for living systems. Although atmospheric nitrogen abounds (more than 75%), few living creatures are capable of using atmospheric nitrogen in its diatomic form, N2 gas.

  3. Ammonia production - Wikipedia

    en.wikipedia.org/wiki/Ammonia_production

    Ammonia production takes place worldwide, mostly in large-scale manufacturing plants that produce 183 million metric tonnes [1] of ammonia (2021) annually. [2][3] Leading producers are China (31.9%), Russia (8.7%), India (7.5%), and the United States (7.1%). 80% or more of ammonia is used as fertilizer. Ammonia is also used for the production ...

    Ammonia pollution. Estimated increase in annual mean surface concentration of particulate matter resulting from ammonia emissions associated with food export. The lichen Bryoria fuscescens which is sensitive to ammonia pollution. Ammonia pollution is pollution by the chemical ammonia (NH 3) – a compound of nitrogen and hydrogen which is a ...

  5. Ammonia solution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_solution

    Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH+. 4] [OH−.

  6. Haber process - Wikipedia

    en.wikipedia.org/wiki/Haber_process

    The Haber process, [1] also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. [2][3] It converts atmospheric nitrogen (N 2) to ammonia (NH 3) by a reaction with hydrogen (H 2) using a finely divided iron metal catalyst: This reaction is slightly favorable in terms of enthalpy, but is disfavored in ...

  7. Ammonium - Wikipedia

    en.wikipedia.org/wiki/Ammonium

    Ammonium is a modified form of ammonia that has an extra hydrogen atom. It is a positively charged (cationic) molecular ion with the chemical formula NH+ 4 or [NH4]+. It is formed by the addition of a proton (a hydrogen nucleus) to ammonia (NH3).

    The (s) notation indicates equilibrium temperature of vapor over solid. Otherwise temperature is equilibrium of vapor over liquid. log10 of anydrous ammonia vapor pressure. Uses formula shown below. Vapor-pressure formula for ammonia: [4] log 10P = A – B / (T − C), where P is pressure in k Pa, and T is temperature in kelvins;

  9. Hyperammonemia - Wikipedia

    en.wikipedia.org/wiki/Hyperammonemia

    Hyperammonemia. Due to accumulation of argininosuccinate, citrulline, and arginine in the liver when the urea cycle is deficient. Hyperammonemia, or high ammonia levels, is a metabolic disturbance characterised by an excess of ammonia in the blood. It is a dangerous condition that may lead to brain injury and death. It may be primary or secondary.
