  2. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    2 has an overall charge of −1, so each of its two equivalent oxygen atoms is assigned an oxidation state of − ⁠ 1 / 2 ⁠. This ion can be described as a resonance hybrid of two Lewis structures, where each oxygen has an oxidation state of 0 in one structure and −1 in the other.

  3. Nitroxylic acid - Wikipedia

    en.wikipedia.org/wiki/Nitroxylic_acid

    Nitroxylic acid or hydronitrous acid is an unstable reduced oxonitrogen acid. It has formula H 4 N 2 O 4 containing nitrogen in the +2 oxidation state. [1] It consists of a central pair of bonded nitrogen atoms with four hydroxyl groups around them, giving rise to hydrazine-1,1,2,2-tetrol as an alternate chemical name.

    The oxidation states are also maintained in articles of the elements (of course), and systematically in the table {{Infobox element/symbol-to-oxidation-state}} See also [ edit ]

  5. Frost diagram - Wikipedia

    en.wikipedia.org/wiki/Frost_diagram

    The oxidation state (sometimes also called oxidation number as on the x axis of two illustrating figures on this page) of the species is shown on the x axis of the 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 ...

    en.wikipedia.org/wiki/Ellingham_diagram

    The Ellingham diagram plots the Gibbs free energy change (ΔG) for each oxidation reaction as a function of temperature. For comparison of different reactions, all values of ΔG refer to the reaction of the same quantity of oxygen, chosen as one mole O (12 mol O 2) by some authors [2] and one mole O 2 by others. [3] The diagram shown ...

    en.wikipedia.org/wiki/Nitrogen_compounds

    The chemical element nitrogen is one of the most abundant elements in the universe and can form many compounds. 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.

  8. Latimer diagram - Wikipedia

    For example, for oxygen, the species would be in the order O 2 (0), H 2 O 2 (–1), H 2 O (-2): The arrow between O 2 and H 2 O 2 has a value +0.68 V over it, it indicates that the standard electrode potential for the reaction: O 2 (g) + 2 H + + 2 e − ⇄ H 2 O 2 (aq) is 0.68 volts.

  9. Mixed oxides of nitrogen - Wikipedia

    en.wikipedia.org/wiki/Mixed_oxides_of_nitrogen

    Mixed oxides of nitrogen (MON) are solutions of dinitrogen trioxide (N 2 O 3) in dinitrogen tetroxide/nitrogen dioxide (N 2 O 4 and NO 2). It may be used as an oxidizing agent in rocket propulsion systems. [1] Mixed oxides of nitrogen are produced by dissolving nitric oxide (NO) gas in liquid dinitrogen tetroxide. Nitric oxide reacts with ...
