    en.wikipedia.org/wiki/Chemical_equation

    A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and chemical formulas.The reactant entities are given on the left-hand side and the product entities are on the right-hand side with a plus sign between the entities in both the reactants and the products, and an arrow that points towards the products to show the direction of the reaction.

  3. Boudouard reaction - Wikipedia

    en.wikipedia.org/wiki/Boudouard_reaction

    2 from its component elements is almost constant and independent of the temperature, while the free energy of formation of CO decreases with temperature. [3] At high temperatures, the forward reaction becomes endergonic , favoring the ( exergonic ) reverse reaction toward CO, even though the forward reaction is still exothermic .

  4. Octane - Wikipedia

    en.wikipedia.org/wiki/Octane

    Octane is a hydrocarbon and also an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3.Octane has many structural isomers that differ by the location of branching in the carbon chain.

    Equations should be balanced according to the stoichiometry, the number of atoms of each species should be the same on both sides of the equation. This is achieved by scaling the number of involved molecules (A, B, C and D in a schematic example below) by the appropriate integers a, b, c and d. [11] a A + b B → c C + d D

    Paul Sabatier (1854-1941) winner of the Nobel Prize in Chemistry in 1912 and discoverer of the reaction in 1897. The Sabatier reaction or Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures (optimally 300–400 °C) and pressures (perhaps 3 MPa [1]) in the presence of a nickel catalyst.

  8. Water–gas shift reaction - Wikipedia

    en.wikipedia.org/wiki/Water–gas_shift_reaction

    A typical composition of a commercial LTS catalyst has been reported as 32-33% CuO, 34-53% ZnO, 15-33% Al 2 O 3. [3] The active catalytic species is CuO. The function of ZnO is to provide structural support as well as prevent the poisoning of copper by sulfur. The Al 2 O 3 prevents dispersion and pellet shrinkage. The LTS shift reactor operates ...
