  2. Hydrochloric acid - Wikipedia

    en.wikipedia.org/wiki/Hydrochloric_acid

    Hydrochloric acid has been used for dissolving calcium carbonate, e.g. such things as de-scaling kettles and for cleaning mortar off brickwork. When used on brickwork the reaction with the mortar only continues until the acid has all been converted, producing calcium chloride, carbon dioxide, and water: CaCO 3 + 2 HCl → CaCl 2 + CO 2 + H 2 O

  3. Hydrogen chloride - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_chloride

    Most hydrogen chloride is consumed in the production of hydrochloric acid. It is also used in the production of vinyl chloride and many alkyl chlorides. [13] Trichlorosilane, a precursor to ultrapure silicon, is produced by the reaction of hydrogen chloride and silicon at around 300 °C. [18] Si + 3 HCl → HSiCl 3 + H 2

    en.wikipedia.org/wiki/Chloric_acid

    Chloric acid, H Cl O 3, is an oxoacid of chlorine, and the formal precursor of chlorate salts. It is a strong acid ( p K a ≈ −2.7) and an oxidizing agent . Properties

  6. Landfill gas utilization - Wikipedia

    en.wikipedia.org/wiki/Landfill_Gas_Utilization

    General accepted values are an exhaust gas temperature of 1000 °C with a retention time of 0.3 seconds which is said to result in greater than 98% destruction efficiency. The combustion temperature is an important controlling factor as if greater than 1100 °C, there is a danger of the exponential formation of thermal NOx.

  7. Stoichiometry - Wikipedia

    C 6 H 6 + CH 3 Cl → C 6 H 5 CH 3 + HCl C 6 H 6 + 2 CH 3 Cl → C 6 H 4 (CH 3) 2 + 2 HCl C 6 H 6 + n CH 3 Cl → C 6 H 6−n (CH 3) n + n HCl. In this example, which reaction takes place is controlled in part by the relative concentrations of the reactants.

  9. Molar concentration - Wikipedia

    en.wikipedia.org/wiki/Molar_concentration

    Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [2] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase : [3]
