cs2 oxidation number

Oxidation number is defined as a number assigned to a element which represents the number of electron lost or gained by the element. We have investigated production of carbon- and sulfur-containing end products of the OH-initiated oxidation of CS 2 in the presence of O 2, an important atmospheric chemical reaction which is known to proceed via the following three elementary steps: OH + CS 2 + M ↔ CS 2 OH + M; CS 2 OH + O 2 → products. The waste product (carbon disulfide) is also much more reactive than carbon dioxide, the normal waste product. Chem. DOI: 10.1021/ja003421p. SH+CS=CS2 +H was important for CS2 formation and with presence of O2, CS2 was likely to be consumed via oxidation reactions. The oxidation state, often called the oxidation number, is an indicator of the degree of oxidation (loss of electrons) of an atom in a chemical compound.Hope this answers the question.

If it's a molecule then the sum of the two oxidation numbers has to be equal to 0, unless a charge is shown on the molecule. Metals only have positive oxidation numbers. Have a nice day. In the oxidation number change method the underlying principle is that the gain in the oxidation number (number of electrons) in one reactant must be equal to the loss in the oxidation number of the other reactant. ChemInform 1990, 21 (26) DOI: 10.1002/chin.199026327. It contains carbon in its +4 oxidation state and sulfur in its -2 oxidation state. Nonmetals can be both.
