Nitrogen triiodide atomic shape. The structures and bonds that make up a contact explosive contribute to its instability. Covalent compounds that have a large unequal sharing of electrons have the capability to fall apart very easily and explosively. Nitrogen triiodide is a perfect example of this property.
Nitroglycerin (NG) (alternative spelling of nitroglycerine), also known as trinitroglycerol (TNG), nitro, glyceryl trinitrate (GTN), or 1,2,3-trinitroxypropane, is a dense, colorless or pale yellow, oily, explosive liquid most commonly produced by nitrating glycerol with white fuming nitric acid under conditions appropriate to the formation of the nitric acid ester.
The gaseous state of water is lighter than air (density 0.804 g/L at STP, average molecular mass 18.015 g/mol) due to water's low molar mass when compared with typical atmospheric gases such as nitrogen gas (N 2). It is non-flammable and much cheaper than helium. The concept of using steam for lifting is therefore already 200 years old.
A suicide bag, also known as an exit bag or hood, [1] [2] is part of a euthanasia device consisting of a large plastic bag with a drawcord used to die by suicide through inert gas asphyxiation. It is usually used in conjunction with a flow of an inert gas that is lighter or less dense than air, like helium or nitrogen.
operate at high pressure (on the order of 20 MPa [48]); implement one or more catalysts [49] to accelerate the synthesis of ammonia; operate at a high temperature (between 500 °C and 600 °C) to obtain the best efficiency in the presence of the catalyst; since about 5% of the N 2 and H 2 molecules react with each passage in the chemical reactor:
Any large, smoothbore, muzzle-loading gun—used before the advent of breech-loading, rifled guns—may be referred to as a cannon, though once standardised names were assigned to different-sized cannon, the term specifically referred to a gun designed to fire a 42-pound (19 kg) shot, as distinct from a demi-cannon – 32 pounds (15 kg ...
The bombs were left over from the German army and were meant to be used in the Battle of Passchendaele in World War I. It was the largest collection of chemical weapons ever found in Belgium. [67] A large amount of chemical weapons, including mustard gas, was found in a neighborhood of Washington, D.C. The cleanup was completed in 2021. [68]
A commonly used system manufactured by Poisk uses three high-pressure composite cylinders filled to 260 Bar at 20 degrees Celsius. The dimensions of the cylinders are 19 inches (480 mm) long, 4.25 inches (108 mm) diameter, and weight under 2.7 kilograms (6.0 lb). At a two-liter per minute flow the cylinders last approximately 6.5 hours each. [7]
