Hydrogen sulphide. This poisonous gas is usually prepared from ferrous sulphide and dilute hydiochloric acid (1 3) in a Kipp s apparatus it should be washed with water to remove acid spray. 

Molybdenum hexafluoride is classified as a corrosive and poison gas. It is stored and shipped in steel, stainless steel, or Monel cylinders approved by DOT. Electronic and semiconductor industries prefer the cylinders equipped with valves which have Compressed Gas Association (CGA) 330 outlets. 

Oxygen difluoride must be regarded as a highly poisonous gas, somewhat more toxic than fluoriae. It has a foul odor with a limit of detectabiUty of 0.1—0.5 ppm. Repeated exposure of rats to 0.5 ppm OF2 produced death repeated exposure to 0.1 ppm, however, caused no discernible effects. 

Shipment and Storage. Liquid sulfur dioxide is commonly shipped in North America using 55- and 90-t tank cars, 20-ton tank tmcks, 1-ton cylinders, and 150-lb cylinders. Cylinders made of specified steel are affixed with the green label for nonflammable gases. The DOT classification is Poison Gas, Inhalation Ha2ard. Purchasers of tank-car quantities are required to have adequate storage faciUties for prompt transfer. 

Stibiae may be inadvertentiy formed by acidified reducing agents reacting with antimony-containing materials. It is an extremely poisonous gas which causes blood destmction and damage to the fiver and kidneys (2). 

Arsenic vapor [12187-88-5] As, does not combine direcdy with hydrogen to form hydrides. However, arsine (arsenic hydride) [7784-42-17, AsH, a highly poisonous gas, forms if an intermetaUic compound such as AlAs is hydrolyzed or treated with HQ. Arsine may also be formed when arsenic compounds are reduced using zinc in hydrochloric acid. Heating to 250°C decomposes arsine into its elements.

Carbon Monoxide a criteria air pollutant that is a colorless, odorless, poisonous gas produced by ineomplete combustion particularly, incomplete burning of earbon-based fuels, e.g., gasoline, oil, and wood.

Oxygen fluoride is a colourless, very poisonous gas that condenses to a pale-yellow liquid (mp... 

Hydrogen sulfide is the only thermodynamically stable sulfane it occurs widely in nature as a result of volcanic or bacterial action and is, indeed, a prime source of elemental 8 (p. 647). It has been known since earliest times and its classical chemistry has been extensively studied since the seventeenth century.H28 is a foul smelling, very poisonous gas familiar to all students of chemistry. Its smell is noticeable at 0.02 ppm but the gas tends to anaesthetize the olefactory senses and the intensity of the smell is therefore a dangerously unreliable guide to its concentration. H28 causes irritation at 5 ppm, headaches and nausea at 10 ppm and immediate paralysis and death at 100 ppm it is therefore as toxic and as dangerous as HCN. 

H2Se (like H2O and H2S) can be made by direct combination of the elements (above 350°), but H2Te and H2P0 cannot be made in this way because of their thermal instability. H2Se is a colourless, offensive-smelling poisonous gas which can be made by hydrolysis of Al2Se3, the action of dilute mineral acids on FeSe or the surface-catalysed reaction of gaseous Se and H2 ... 

Giftgas, n. poison gas, toxic gas. -krieg, m. poison-gas warfare. 

Hydrogen cyanide (HCN) is a poisonous gas that is used in gas chambers for the execution of those sentenced to death. It can be formed by the following reaction ... 

Carbon monoxide, CO, is a poisonous gas. It can be obtained by burning carbon in a limited amount of oxygen. Given... 

During World War I. Haber was in charge of the German poison gas program. In April of 1915. the Germans used chlorine for the first time on the Western front, causing 5000 fatalities. Haber s wife. Clara, was aghast she pleaded with her husband to forsake poison gas. When he adamantly refused to do so. she committed suicide. 

The elements in a compound are not just mixed together. Their atoms are actually joined, or bonded, to one another in a specific way due to a chemical change (see Section A). The result is a substance with chemical and physical properties different from those of the elements that form it. For example, when sulfur is ignited in air, it combines with oxygen from the air to form the compound sulfur dioxide. Solid yellow sulfur and odorless oxygen gas produce a colorless, pungent, and poisonous gas (Fig. C.l). 

Seif-Test D.4B Write the formulas for (a) cesium sulfide tetrahydrate (b) manganese(VII) oxide (c) hydrogen cyanide (a poisonous gas) (d) disulfur dichloride. 

Self-Test 2.8A Suggest a likely structure for the poisonous gas phosgene, COCL. Write its Lewis structure and formal charges. 

Sulfur forms several oxides that in atmospheric chemistry are referred to collectively as SOx (read sox ). The most important oxides and oxoacids of sulfur are the dioxide and trioxide and the corresponding sulfurous and sulfuric acids. Sulfur burns in air to form sulfur dioxide, S02 (11), a colorless, choking, poisonous gas (recall Fig. C.1). About 7 X 1010 kg of sulfur dioxide is produced annually from the decomposition of vegetation and from volcanic emissions. In addition, approximately 1 X 1011 kg of naturally occurring hydrogen sulfide is oxidized each year to the dioxide by atmospheric oxygen ... 

C02-0029. The following is a molecular picture of carbon reacting with oxygen to form carbon monoxide, a deadly poisonous gas. Describe how this picture illustrates the features of atomic theoiy. 

Hydrogen cyanide (HCN) is an extremely poisonous gas with an odor resembling that of almonds. Approximately one billion pounds of HCN are produced each year, most of which are used to prepare starting materials for polymers. Construct a complete bonding picture for HCN and sketch the various orbitals.
