  2. HAZMAT Class 5 Oxidizing agents and organic peroxides

    en.wikipedia.org/wiki/HAZMAT_Class_5_Oxidizing...

    5.1: Liquid Any material which exhibits a mean pressure rise time less than or equal to the pressure rise time of a 1:1 nitric acid (65 percent)/cellulose mixture and the criteria for Packing Group I and II are not met. Group II 5.2: All All Division 5.2 materials do not have a packing group in Column 5 of the 49 CFR 172.101 Table.

  3. Henry's law - Wikipedia

    en.wikipedia.org/wiki/Henry's_law

    Although the standard concentration c° is taken to be 1 mol/L by convention, the standard state is a hypothetical solution of 1 mol/L in which the solute has its limiting infinite-dilution properties. This has the effect that all non-ideal behavior is described by the activity coefficient: the activity coefficient at 1 mol/L is not necessarily ...

    en.wikipedia.org/wiki/List_of_chemistry_mnemonics

    A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.

  5. Chromatography - Wikipedia

    en.wikipedia.org/wiki/Chromatography

    Chromatography, pronounced / ˌ k r oʊ m ə ˈ t ɒ ɡ r ə f i /, is derived from Greek χρῶμα chrōma, which means "color", and γράφειν gráphein, which means "to write".". The combination of these two terms was directly inherited from the invention of the technique first used to separate biological pigme

  6. 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 ...

    en.wikipedia.org/wiki/HAZMAT_Class_4_Flammable...

    Division 4.1: Flammable Solid . Flammable solids are any of the following four types of materials: Desensitized Explosives: explosives that, when dry, are Explosives of Class 1 other than those of compatibility group A, which are wetted with sufficient water, alcohol, or plasticizer to suppress explosive properties; and are specifically authorized by name either in the 49CFR 172.101 Table or ...

  8. Organic chemistry - Wikipedia

    en.wikipedia.org/wiki/Organic_chemistry

    Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1] Study of structure determines their structural formula.

  9. Silver chloride - Wikipedia

    en.wikipedia.org/wiki/Silver_chloride

    The solubility product, K sp, for AgCl in water is 1.77 × 1010 at room temperature, which indicates that only 1.9 mg (that is, ) of AgCl will dissolve per liter of water. [1] The chloride content of an aqueous solution can be determined quantitatively by weighing the precipitated AgCl, which conveniently is non-hygroscopic since AgCl is ...
