2. Gibbs–Helmholtz equation - Wikipedia

   en.wikipedia.org/wiki/Gibbs–Helmholtz_equation

   The definition of the Gibbs function is = + where H is the enthalpy defined by: = +. Taking differentials of each definition to find dH and dG, then using the fundamental thermodynamic relation (always true for reversible or irreversible processes): = where S is the entropy, V is volume, (minus sign due to reversibility, in which dU = 0: work other than pressure-volume may be done and is equal ...

3. Thermodynamic databases for pure substances - Wikipedia

   en.wikipedia.org/wiki/Thermodynamic_databases...

   Hence, the main functional application of Gibbs energy from a thermodynamic database is its change in value during the formation of a compound from the standard-state elements, or for any standard chemical reaction (ΔG° form or ΔG° rx). The SI units of Gibbs energy are the same as for enthalpy (J/mol).

4. Element–reactant–product table - Wikipedia

   en.wikipedia.org/wiki/Element–reactant...

   An element–reaction–product table is used to find coefficients while balancing an equation representing a chemical reaction. Coefficients represent moles of a substance so that the number of atoms produced is equal to the number of atoms being reacted with. [1] This is the common setup: Element: all the elements that are in the reaction ...

5. Conjugate (acid-base theory) - Wikipedia

   In summary, this can be represented as the following chemical reaction: + + Johannes Nicolaus Brønsted (left) and Martin Lowry (right). Johannes Nicolaus Brønsted and Martin Lowry introduced the Brønsted–Lowry theory, which said that any compound that can give a proton to another compound is an acid, and the compound that receives the ...

6. 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]

7. Brønsted–Lowry acid–base theory - Wikipedia

   en.wikipedia.org/wiki/Brønsted–Lowry_acid...

   The Brønsted–Lowry theory (also called proton theory of acids and bases [1]) is an acid–base reaction theory which was first developed by Johannes Nicolaus Brønsted and Thomas Martin Lowry independently in 1923.
