Iodine is a chemical element with the symbol I and atomic number 53. Ammonia is an inorganic compound of nitrogen and hydrogen with the formula NH 3.A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. 9H 2 O.Both the anhydrous and the hydrated salts in pure crystalline form are colorless solids, although technical grades of sodium sulfide are generally yellow to brick red owing to the presence of polysulfides and commonly supplied as a crystalline mass, in flake form, or as a Lithium aluminium hydride, commonly abbreviated to LAH, is an inorganic compound with the chemical formula Li Al H 4.It is a white solid, discovered by Finholt, Bond and Schlesinger in 1947. Ammonia The element was discovered by the French chemist Bernard Courtois in 1811 and was named two years Hydrazoic acid, also known as hydrogen azide or azoimide, is a compound with the chemical formula HN 3. Among the elements, fluorine ranks 24th in universal abundance and Organotin chemistry is part of the wider field of organometallic chemistry.The first organotin compound was diethyltin diiodide ((CH 3 CH 2) 2 SnI 2), discovered by Edward Frankland in 1849.The area grew rapidly in the 1900s, especially after the discovery of the At standard conditions hydrogen is a gas of diatomic molecules having the formula H 2.It is colorless, odorless, tasteless, non-toxic, and highly combustible.Hydrogen is the most abundant chemical substance in the universe, constituting roughly 75% of all normal The underground mine gas term for foul-smelling hydrogen sulfide-rich gas mixtures is stinkdamp.Swedish chemist Carl Wilhelm Titanium, rarely used on its own, is more often employed to intensify and brighten other colorizing additives. Hydrogen fluoride boils at near room temperature, much higher than other hydrogen halides. Halides of the structure PoX 2, PoX 4 and PoF 6 are known. Hydrogen is present in all organic compounds. Hydrogen is present in all organic compounds. Empty string with an inhalation toxicity lower than or equal to 1000 ml/m3 and saturated vapour concentration greater than or equal to 10 LC50 (UN No. Hydrogen iodide, like other hydrogen halides, is toxic. Although the formula for sodium chloride is NaCl, the compound does not contain actual NaCl molecules. Hydrogen iodide, like other hydrogen halides, is toxic. Mercury (element It is a compound of nitrogen and hydrogen, and is therefore a pnictogen hydride.It was first isolated in 1890 by Theodor Curtius.
