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
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 ...
This structure can also be considered to be a distorted hcp lattice with the nearest neighbours in the same plane being approx 16% farther away [18] β-Po: A i: Rhombohedral: R 3 m (No. 166) 1 (rh.) 3 (hex.) Identical symmetry to the α-Hg structure, distinguished based on details about the basis vectors of its unit cell. γ-Se: A8: Hexagonal ...
Although initially marketed in 1958 as a smoke suppressant for gas turbines, MMT was further developed as an octane enhancer in 1974. When the United States Environmental Protection Agency (EPA) ordered the phase out of TEL in gasoline in 1973, new fuel additives were sought. TEL has been used in certain countries as an additive to increase the ...
