  2. Tetramethylammonium chloride - Wikipedia

    en.wikipedia.org/wiki/Tetramethylammonium_chloride

    The chemical formula (CH 3) 4 N + Cl − is often abbreviated further as Me 4 N + Cl −. It is a hygroscopic colourless solid that is soluble in water and polar organic solvents. Tetramethylammonium chloride is a major industrial chemical, being used widely as a chemical reagent [1] and also as a low-residue bactericide in such processes as ...

  3. Liquid nitrogen - Wikipedia

    en.wikipedia.org/wiki/Liquid_nitrogen

    Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water, specific heat of 1040 J ⋅kg −1 ⋅K −1 and heat of vaporization of 200 kJ⋅kg −1 makes it extremely useful in a wide range of ...

  4. Chloromethane - Wikipedia

    en.wikipedia.org/wiki/Chloromethane

    ch 3 oh + hcl → ch 3 cl + h 2 o A smaller amount of chloromethane is produced by treating a mixture of methane with chlorine at elevated temperatures. This method, however, also produces more highly chlorinated compounds such as dichloromethane , chloroform , and carbon tetrachloride .

  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. Chloroform - Wikipedia

    en.wikipedia.org/wiki/Chloroform

    Chloroform, [10] or trichloromethane (often abbreviated as TCM), is an organochloride with the formula C H Cl 3 and a common solvent.It is a volatile, colorless, sweet-smelling, dense liquid produced on a large scale as a precursor to refrigerants and PTFE. [11]

  7. Phase diagram - Wikipedia

    en.wikipedia.org/wiki/Phase_diagram

    This reflects the fact that, at extremely high temperatures and pressures, the liquid and gaseous phases become indistinguishable, [3] in what is known as a supercritical fluid. In water, the critical point occurs at around T c = 647.096 K (373.946 °C), p c = 22.064 MPa (217.75 atm) and ρ c = 356 kg/m 3 .

  8. Nitrogen compounds - Wikipedia

    It can take several oxidation states; but the most common oxidation states are -3 and +3. Nitrogen can form nitride and nitrate ions. It also forms a part of nitric acid and nitrate salts. Nitrogen compounds also have an important role in organic chemistry, as nitrogen is part of proteins, amino acids and adenosine triphosphate.

  9. Chlorine nitrate - Wikipedia

    en.wikipedia.org/wiki/Chlorine_nitrate

    It can be produced by the reaction of dichlorine monoxide and dinitrogen pentoxide at 0 °C: [3] Cl 2 O + N 2 O 5 → 2 ClONO 2. or by the reaction: [4] ClF + HNO 3 → HF + ClONO 2. It can also react with alkenes: (CH 3) 2 C=CH 2 + ClONO 2 → O 2 NOC(CH 3) 2 CH 2 Cl. Chlorine nitrate reacts with metal chlorides: [5] 4 ClONO 2 + TiCl 4 → Ti ...
