  2. Gas evolution reaction - Wikipedia

    en.wikipedia.org/wiki/Gas_evolution_reaction

    A gas evolution reaction is a chemical reaction in which one of the end products is a gas such as oxygen or carbon dioxide. [ 1 ] [ 2 ] Gas evolution reactions may be carried out in a fume chamber when the gases produced are poisonous when inhaled or explosive.

  3. Exothermic process - Wikipedia

    en.wikipedia.org/wiki/Exothermic_process

    Some polymerization reactions such as the setting of epoxy resin; The reaction of most metals with halogens or oxygen; Nuclear fusion in hydrogen bombs and in stellar cores (to iron) Nuclear fission of heavy elements; The reaction between zinc and hydrochloric acid; Respiration (breaking down of glucose to release energy in cells)

  4. Single displacement reaction - Wikipedia

    en.wikipedia.org/wiki/Single_displacement_reaction

    A single-displacement reaction, also known as single replacement reaction or exchange reaction, is an archaic concept in chemistry. It describes the stoichiometry of some chemical reactions in which one element or ligand is replaced by atom or group. [1] [2] [3] It can be represented generically as: + +

  5. Zinc compounds - Wikipedia

    en.wikipedia.org/wiki/Zinc_compounds

    The reaction of zinc with water is slowed by this passive layer. When this layer is corroded by acids such as hydrochloric acid and sulfuric acid, the reaction proceeds with the evolution of hydrogen gas. [1] [9] Zn + 2 H + → Zn 2+ + H 2. Zinc reacts with alkalis as with acids.

  6. Catalytic oxidation - Wikipedia

    en.wikipedia.org/wiki/Catalytic_oxidation

    Catalytic oxidation are processes that rely on catalysts to introduce oxygen into organic and inorganic compounds. Many applications, including the focus of this article, involve oxidation by oxygen. Such processes are conducted on a large scale for the remediation of pollutants, production of valuable chemicals, and the production of energy. [1]

  7. Oxidizing agent - Wikipedia

    en.wikipedia.org/wiki/Oxidizing_agent

    The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).

  8. Hydrogen chloride - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_chloride

    Cl 2 + H 2 → 2 HCl. As the reaction is exothermic, the installation is called an HCl oven or HCl burner. The resulting hydrogen chloride gas is absorbed in deionized water, resulting in chemically pure hydrochloric acid. This reaction can give a very pure product, e.g. for use in the food industry. The reaction can also be triggered by blue ...

  9. Zinc chloride - Wikipedia

    en.wikipedia.org/wiki/Zinc_chloride

    The use of zinc chloride as a flux, sometimes in a mixture with ammonium chloride (see also Zinc ammonium chloride), involves the production of HCl and its subsequent reaction with surface oxides. Zinc chloride forms two salts with ammonium chloride: [NH 4] 2 [ZnCl 4] and [NH 4] 3 [ZnCl 4]Cl, which decompose on heating liberating HCl, just as ...
