	Ammonia - Wikipedia (Site not responding. Last check: 2007-10-11)
		Ammonia is a chemical compound whose molecule consists of one atom of nitrogen (N) and three atoms of hydrogen (H) with the formula NH and the structure:
		Ammonia finds a wide application in organic chemistry as a synthetic reagent; it reacts with alkyl[?] iodides to form amines, with esters to form acid amides[?], with halogen fatty acids to form amino acids; while it also combines with isocyanic esters to form alkyl ureas and with the mustard oils to form alkyl thioureas[?].
		The Haber process to produce ammonia from the nitrogen contained in the air was developed by Fritz Haber and Carl Bosch in 1909 and patented in 1910.

	Ammonia
		Ammonia is found in small quantities as the carbonate in the atmosphere, being produced from the putrefaction of nitrogenous animal and vegetable matter.
		Ammonium salts are also found in small quantities in rain-water, whilst ammonium chloride (sal-ammoniac) and ammonium sulfate are found in volcanic districts; and crystals of ammonium bicarbonate have been found in Patagonian guano.
		The commercial salt was formerly known as\nsal-volatile or salt of hartshorn and was formerly obtained by\nthe dry distillation of nitrogenous organic matter such as hair,\nhorn, decomposed urine, etc., but is now obtained by heating a\nmixture of sal-ammoniac, or ammonium sulfate and chalk, to\nredness in iron retorts, the vapours being condensed in leaden\nreceivers.

	Nitrogen Tri-iodide - MOTM
		When dry solid nitrogen triiodide is touched, even with a feather, it decomposes rather violently.
		It is also formed in swimming pools when the chlorine gas used to disinfect the water reacts with nitrogen compounds found in urine, and can be a health risk to people like lifeguards who work continuously around the water.
		In all these compounds, the nitrogen atom has a complete "octet", with four outer-shell electron pairs; one of these is a non-bonding ("lone") pair.

		Metallic fuels (eg aluminium) may be added to increase the heat of reaction.
		The infamous nitrogen tri-iodide (touch powder) produced by the reaction of ammonia with iodine, is not actually NI3, but a nitrogen iodide/ammonia complex with the structure NI3(NH3)n where n = 1, 3, or 5 - depending on conditions.
		NI3 has only recently been isolated, and is stable at -196C, decomposes slowly at -78C, and decomposes spontaneously at 0C [6].
