Hydrogen sulfide is a chemical compound with the formula H 2 S. It is a colorless chalcogen-hydride gas , and is toxic, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs . [ 11 ]
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
Sour gas is natural gas or any other gas containing significant amounts of hydrogen sulfide (H 2 S). Natural gas is usually considered sour if there are more than 5.7 milligrams of H 2 S per cubic meter of natural gas, which is equivalent to approximately 4 ppm by volume under standard temperature and pressure.
Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Hydrogen sulfide is a very toxic and corrosive gas characterised by a typical odour of "rotten egg". −85.7: −60.20: 7783-06-4: CdS: Cadmium sulfide can be used in photocells. 1750: 1306-23-6: Calcium polysulfide ("lime sulfur") is a traditional fungicide in gardening. CS 2: Carbon disulfide is a precursor to organosulfur compounds. −111.6 ...
energy/mole of fuel; energy/mass of fuel; energy/volume of the fuel; There are two kinds of enthalpy of combustion, called high(er) and low(er) heat(ing) value, depending on how much the products are allowed to cool and whether compounds like H 2 O are allowed to condense. The high heat values are conventionally measured with a bomb calorimeter ...
