0. CO2 is electrically neutral. C is +4 and O is 2(-2)
The oxidation number of carbon in CO2 is +4, while the oxidation number of oxygen is -2.
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 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.
The oxidation number for carbon (C) in carbon dioxide (CO2) is +4. Each oxygen atom has an oxidation number of -2, so in the compound CO2, the total oxidation number must equal 0.
The oxidation number for H is +1, and the oxidation number for O is -1.
The oxidation number of carbon in CO2 is +4, while the oxidation number of oxygen is -2.
-2 for O +4 for C
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.

The oxidation number for H is +1, and the oxidation number for O is -1.
The oxidation number of carbon in carbon dioxide (CO2) is +4. This is because oxygen typically has an oxidation number of -2, and since there are two oxygen atoms bonded to the carbon atom in CO2, the carbon atom must have an oxidation number of +4 to balance the charge.
In N2O5, the oxidation number of N (nitrogen) is +5 and the oxidation number of O (oxygen) is -2.
The central carbon atom has an oxidation number of -2 (O is -2, H is +1)
The oxidation number of oxygen (O) in most compounds, including sulfate (SO4), is typically -2. In Na2SO4, sodium (Na) has an oxidation number of +1. To calculate the oxidation number of oxygen in the compound, you would use the equation: 2(oxidation number of Na) + oxidation number of S + 4(oxidation number of O) = 0. By plugging in the known values, you can solve for the oxidation number of oxygen in Na2SO4.
The oxidation number of O in any elemental form (e.g. O2, O3) is zero. Typically in chemical compounds the oxidation number of O is -2 (oxide ion)
+1 for Na +5 for N -2 for each O
