The structure of the pyridine complex has been determined crystallographically. [2] Adducts with other N-heterocycles have also been characterized similarly. [3] Aqueous chromium(VI) oxide peroxide decomposes in a few seconds, turning green as chromium(III) compounds are formed. [4] 2 CrO(O 2) 2 + 7 H 2 O 2 + 6 H + → 2 Cr 3+ + 10 H 2 O + 7 O 2
1,1,1,2,3,3,3-Heptafluoropropane, also called heptafluoropropane, HFC-227ea (ISO name), HFC-227 or FM-200, as well as apaflurane , is a colourless, odourless gaseous halocarbon commonly used as a gaseous fire suppression agent.
Shipping container for the gas, shown in Japan Pentafluoroethane in a near azeotropic mixture with difluoromethane is known as R-410A , a common replacement for various chlorofluorocarbons (commonly known as Freon ) in new refrigerant systems.
CR gas is a lachrymatory agent (LA), exerting its effects through activation of the TRPA1 channel. [ 5 ] [ 6 ] [ 7 ] Its effects are approximately 6 to 10 times more powerful than those of CS gas . CR causes intense skin irritation, in particular around moist areas; blepharospasm , causing temporary blindness; and coughing, gasping for breath ...
Gas electron diffraction (GED) is one of the applications of electron diffraction techniques. [1] The target of this method is the determination of the structure of gaseous molecules, i.e., the geometrical arrangement of the atoms from which a molecule is built up. GED is one of two experimental methods (besides microwave spectroscopy) to ...
This model is employed when the pores in the polymer membrane appear and disappear faster relative to the movement of the particles. [5] In a typical membrane system the incoming feed stream is separated into two components: permeant and retentate. Permeant is the gas that travels across the membrane and the retentate is what is left of the feed.
Gallium(II) sulfide, GaS, is a chemical compound of gallium and sulfur. The normal form of gallium(II) sulfide as made from the elements has a hexagonal layer structure containing Ga 2 4+ units which have a Ga-Ga distance of 248pm. [1] This layer structure is similar to GaTe, GaSe and InSe. [1]
Cyanogen gas is an irritant to the eyes and respiratory system. Inhalation can lead to headache, dizziness, rapid pulse, nausea, vomiting, loss of consciousness, convulsions, and death, depending on exposure. [18] Lethal dose through inhalation typically ranges from 100 to 150 milligrams (1.5 to 2.3 grains).
