  2. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    8, has been described as having a carbon oxidation state of − ⁠ 8 / 3 ⁠. [19] Again, this is an average value since the structure of the molecule is H 3 C−CH 2 −CH 3, with the first and third carbon atoms each having an oxidation state of −3 and the central one −2.

  3. 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 ...

  4. Chemical oxygen demand - Wikipedia

    en.wikipedia.org/wiki/Chemical_oxygen_demand

    The basis for the COD test is that nearly all organic compounds can be fully oxidized to carbon dioxide with a strong oxidizing agent under acidic conditions. The amount of oxygen required to oxidize an organic compound to carbon dioxide, ammonia, and water is given by:

  5. Cobalt(II) oxide - Wikipedia

    en.wikipedia.org/wiki/Cobalt(II)_oxide

    Cobalt(II) oxide is prepared by oxidation of cobalt powder with air or by thermal decomposition of cobalt(II) nitrate or the carbonate. [3] [4] Cobalt(II,III) oxide decomposes to cobalt(II) oxide at 950 °C: [7] 2 Co 3 O 4 → 6 CoO + O 2. It may also be prepared by precipitating the hydroxide, followed by thermal dehydration: [citation needed]

  6. Combustion analysis - Wikipedia

    en.wikipedia.org/wiki/Combustion_analysis

    Applications for combustion analysis involve only the elements of carbon (C), hydrogen (H), nitrogen (N), and sulfur (S) as combustion of materials containing them convert these elements to their oxidized form (CO 2, H 2 O, NO or NO 2, and SO 2) under high temperature high oxygen conditions.

    At least five drone shows have been canceled or have paused the use of the systems, after several drones struck a crowd at a holiday show in Orlando on December 21.

  8. Frost diagram - Wikipedia

    en.wikipedia.org/wiki/Frost_diagram

    Oxidation states are unitless and are also scaled in positive and negative integers. Most often, the Frost diagram displays oxidation state in increasing order, but in some cases it is displayed in decreasing order. The neutral species of the pure element with a free energy of zero (nE° = 0) also has an oxidation state equal to zero. [2]
