Analysis of the spectrum provides information on global mean properties of ammonia gas and an ammonia ice haze. [193] A total of 149 dark cloud positions were surveyed for evidence of 'dense cores' by using the (J,K) = (1,1) rotating inversion line of NH 3. In general, the cores are not spherically shaped, with aspect ratios ranging from 1.1 to ...
In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: . NH 3 + H 2 O ⇌ NH + 4 + OH −.. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +
NH3, NH-3, NH 3 or NH 3 may refer to: Ammonia (chemical formula NH 3) National Highway 3 (India) National Highway 3 (India, old numbering) New Hampshire Route 3;
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 byproduct of ...
Ammonium is a modified form of ammonia that has an extra hydrogen atom. It is a positively charged molecular ion with the chemical formula NH + 4 or [NH 4] +.It is formed by the addition of a proton (a hydrogen nucleus) to ammonia (NH 3).
Fritz Haber, 1918. 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 finely divided iron metal as a catalyst:

Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group [4] (these may respectively be called alkylamines ...
