    en.wikipedia.org/wiki/Help:Displaying_a_formula

    Use of LaTeX for formulas involving symbols that are not regularly rendered in Unicode (see MOS:BBB) Avoid formulas in section headings, and when this is necessary, use raw HTML (see Finite field for an example) The choice between {} and LaTeX depends on the editor. Converting a page from one format to another must be done with stronger reasons ...

    Open the PostScript file in Scribus. Note the image size and set the paper size to about 10px larger than the largest dimension. NB:SymyxDraw will usually add a full page rectangle to the drawing - ungroup, select rectangle and delete, then select all and re-group structure. Go to File → Export → Save page as SVG.

    |-adds a new row, which should be followed by the same number of cells found in other rows. Note, rowspan="2" and colspan="2" can be used on cells to span multiple rows and columns. Header cells are created with ! Header cell, which can be column or row headers. Data cells are created with | Data cell. A new column can be added by adding ...

  5. Chemical equation - Wikipedia

    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. [1]

  6. Extent of reaction - Wikipedia

    en.wikipedia.org/wiki/Extent_of_reaction

    This formula leads to the Nernst equation when applied to the oxidation-reduction reaction which generates the voltage of a voltaic cell. Analogously, the relation between the change in reaction enthalpy and enthalpy can be defined. For example, [8]

  7. Nernst equation - Wikipedia

    en.wikipedia.org/wiki/Nernst_equation

    In electrochemistry, the Nernst equation is a chemical thermodynamical relationship that permits the calculation of the reduction potential of a reaction (half-cell or full cell reaction) from the standard electrode potential, absolute temperature, the number of electrons involved in the redox reaction, and activities (often approximated by concentrations) of the chemical species undergoing ...

  8. Arrhenius equation - Wikipedia

    en.wikipedia.org/wiki/Arrhenius_equation

    In physical chemistry, the Arrhenius equation is a formula for the temperature dependence of reaction rates.The equation was proposed by Svante Arrhenius in 1889, based on the work of Dutch chemist Jacobus Henricus van 't Hoff who had noted in 1884 that the van 't Hoff equation for the temperature dependence of equilibrium constants suggests such a formula for the rates of both forward and ...
