  2. LMS Ivatt Class 2 2-6-0 - Wikipedia

    en.wikipedia.org/wiki/LMS_Ivatt_Class_2_2-6-0

    The remaining 108 locomotives of the class, numbered 46420–46527 were built by British Railways, and from 46465 (Darlington, 1951) an increase in cylinder diameter of 1 ⁄ 2 inch (13 mm) yielded a tractive effort of 18,510 lb (8,400 kg), 1,100 lb (500 kg) greater than the original design. The LMS classified them 2F, BR as 2MT.

  3. Diatomic carbon - Wikipedia

    en.wikipedia.org/wiki/Diatomic_carbon

    Diatomic carbon (systematically named dicarbon and 1λ 2,2λ 2-ethene), is a green, gaseous inorganic chemical with the chemical formula C=C (also written [C 2] or C 2). It is kinetically unstable at ambient temperature and pressure, being removed through autopolymerisation .

  4. Carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide

    The symmetry of a carbon dioxide molecule is linear and centrosymmetric at its equilibrium geometry. The length of the carbon–oxygen bond in carbon dioxide is 116.3 pm, noticeably shorter than the roughly 140 pm length of a typical single C–O bond, and shorter than most other C–O multiply bonded functional groups such as carbonyls. [19]

    CS 2 once was manufactured by combining carbon (or coke) and sulfur at 800–1000 °C. [13] C + 2S → CS 2. A lower-temperature reaction, requiring only 600 °C, utilizes natural gas as the carbon source in the presence of silica gel or alumina catalysts: [9] 2 CH 4 + S 8 → 2 CS 2 + 4 H 2 S. The reaction is analogous to the combustion of ...

    Homochirality is an obvious characteristic of life on Earth, yet extraterrestrial samples contain largely racemic compounds. [7] It is not known whether homochirality existed before life, whether the building blocks of life must have this particular chirality, or whether life must be homochiral at all.

    [8] [12] Erasing information is a thermodynamically irreversible process that increases the entropy of a system. Although Bennett had reached the same conclusion as Szilard's 1929 paper, that a Maxwellian demon could not violate the second law because entropy would be created, he had reached it for different reasons.

    CCS can be a ligand. It can form an asymmetrical bridge between two molybdenum atoms in Mo2(μ,σ(C):η 2 (C′S)-CCS)(CO) 4 (hydrotris(3,5-dimethylpyrazol-1-yl)borate) 2 In this one carbon atom has a triple bond to a molybdenum and the other has a double bond to the other molybdenum atom, which also has a single bond to the sulfur atom.
