O.S. of C = +4
The oxidation number of carbon in CO2 is +4, while the oxidation number of oxygen is -2.
0. CO2 is electrically neutral. C is +4 and O is 2(-2)
CO is a harmful gas.C shows +2 in CO and it shows +4 in CO2.
The oxidation state of carbon (C) in CO2 is +4. Each oxygen atom in CO2 has an oxidation state of -2, so for the overall molecule to be neutral, carbon must have an oxidation state of +4.
In KO2, O has an oxidation number of -1, K has an oxidation number of +1. In CO2, O has an oxidation number of -2, C has an oxidation number of +4. In K2CO3, O has an oxidation number of -2, C has an oxidation number of +4, and K has an oxidation number of +1. In the given reaction, the oxidation numbers for each atom remain the same as in their individual compounds.

The chemical equation for the oxidation of carbon to carbon dioxide is: C(s) + O2(g) -> CO2(g)
The oxidation number of sodium (Na) is +1. The oxidation number of carbon (C) in a compound is typically +4, except in the case of CO2 where it is +4 for each oxygen (O). In oxalate (C2O4), the overall charge is -2, so the oxidation number of oxygen (O) is -2 in this compound.
H is +1, O is -2 overall carbon will have an oxidation # of -3
CO2 + C → 2CO Carbon dioxide combines with carbon to form carbon monoxide (in the laboratory) by passing CO2 over heated charcoal. In the environment, it is formed by incomplete oxidation of hydrocarbons.
The correct answer is co2+c= 2co
Following the IUPAC definition method (typically taught in the US) O is with few exceptions -2 , H is +1 in this instance (it is only -1 when linked to a reactive metal). Therefore as the overall oxidation state of the molecule is zero as it is uncharged the oxidation number of C is 0. Other answers are possible as there are other ways to work it out a previous contributor offered this answer:- To get the oxidation number for COH2 can be calculated by adding the oxidation of the individual elements. COH2 C is (+4), 2H is (-2) and O is (-2) which equals to 0.
