Properties. Liquid NH 3. Solid NH 3. Two visible states of NH 3. Ammonia is a colourless gas with a characteristically pungent smell. It is lighter than air, its density being 0.589 times that of air. It is easily liquefied due to the strong hydrogen bonding between molecules.
Ammonia | NH3 or H3N | CID 222 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.
Ammonia lewis structure contains three sigma bonds and one lone pair on nitrogen atom. Therefore, there are total of four electrons regions. So, hybridization of center atom, nitrogen is sp 3. Because there are four electrons regions, geometry is tetrahedral and shape is trigonal pyramidal.
NH3 Ammonia. Ammonia has 4 regions of electron density around the central nitrogen atom (3 bonds and one lone pair). These are arranged in a tetrahedral shape. The resulting molecular shape is trigonal pyramidal with H-N-H angles of 106.7°.
3 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.
Hg 2 Cl 2 + 2 NH 3 → Hg + HgCl(NH 2) + NH 4 + + Cl − Uses Nitric Acid production. The most important single use of ammonia is in the production of nitric acid. A mixture of one part ammonia to nine parts air is passed over a platinum gauze catalyst at 850 °C, whereupon the ammonia is oxidized to nitric oxide. 4 NH 3 + 5 O 2 → 4 NO + 6 H ...
