2-Bromobutane is an isomer of 1-bromobutane. Both compounds share the molecular formula C 4 H 9 Br. 2-Bromobutane is also known as sec -butyl bromide or methylethylbromomethane. Because it contains bromine , a halogen, it is part of a larger class of compounds known as alkyl halides .
Bromobutane (molecular formula: C 4 H 9 Br, molar mass: 137.02 g/mol) may refer to either of two chemical compounds: 1-Bromobutane (n-butyl bromide)
Photosynthesis changes sunlight into chemical energy, splits water to liberate O 2, and fixes CO 2 into sugar. Most photosynthetic organisms are photoautotrophs, which means that they are able to synthesize food directly from carbon dioxide and water using energy from light.
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 ...
In its simplest form, photosynthesis is adding water to CO 2 to produce sugars and oxygen, but a complex chemical pathway is involved, facilitated along the way by a range of enzymes and co-enzymes. The enzyme RuBisCO is responsible for "fixing" CO 2 – that is, it attaches it to a carbon-based molecule to form a sugar, which can be used by ...
Hill's finding was that the origin of oxygen in photosynthesis is water (H 2 O) not carbon dioxide (CO 2) as previously believed. Hill's observation of chloroplasts in dark conditions and in the absence of CO 2 , showed that the artificial electron acceptor was oxidized but not reduced, terminating the process, but without production of oxygen ...

1-Bromobutane is the organobromine compound with the formula CH 3 (CH 2) 3 Br. It is a colorless liquid, although impure samples appear yellowish. It is insoluble in water, but soluble in organic solvents. It is primarily used as a source of the butyl group in organic synthesis. It is one of several isomers of butyl bromide.
