Liquid ammonia is the most commonly studied, and best known, non-aqueous ionizing solvent. The most notable property of this compound is its ability to dissolve alkali metals to form strongly coloured, electrically conductive solutions that contain solved electrons.
This kind of ammonia is called liquid ammonia or aqueous ammonia. Once exposed to open air, liquid ammonia quickly turns into a gas. Ammonia is applied directly into soil on farm fields, and is used to make fertilizers for farm crops, lawns, and plants.
Ammonia is an inorganic chemical compound of nitrogen and hydrogen with the formula N H 3. A stable binary hydride and the simplest pnictogen hydride, ammonia is a colourless gas with a distinctive pungent smell.
2 ημέρες πριν · NH 3 + H 2 O ⇌ NH 4 + + OH − These aqueous solutions of ammonia are basic and are sometimes called solutions of ammonium hydroxide (NH 4 OH). The equilibrium, however, is such that a 1.0-molar solution of NH 3 provides only 4.2 millimoles of hydroxide ion.
23 Μαΐ 2018 · Ammonia molecules possess a pyramidal shape, with the nitrogen atom at the vertex. These molecules continually undergo a type of motion called inversion, in which the nitrogen atom passes through the plane of the three hydrogen atoms like an umbrella turning inside out in the wind.
ammonia, Colourless, pungent gas composed of nitrogen and hydrogen, chemical formula NH 3. Easily liquefied by compression or cooling for use in refrigerating and air-conditioning equipment, it is manufactured in huge quantities. Ammonia is made by the Haber-Bosch process (see Fritz Haber).
Ammonia formula is NH3 and its molar mass is 17.03 g/mol. It is a chemical compound made of nitrogen and hydrogen. It is a colourless gas with a very bad pungent smell.
