What is the oxidation number of C in CH2O?

The oxidation number of carbon (C) in CH2O is +2. This is because hydrogen (H) has an oxidation number of +1 and oxygen (O) has an oxidation number of -2, so the sum of the oxidation numbers in CH2O must be zero to balance the charge.


What is oxidation number of C in C204?

The oxidation number of C in Cā‚‚Oā‚„ is +3. Each oxygen atom carries a charge of -2, and since there are 4 oxygen atoms in total with a total charge of -8, the carbon atom's oxidation number must be +3 to balance the charges in the compound.


What is the oxidation number for CO2 equals C?

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.


What is the oxidation number of C in CO3 -2?

The oxidation number of C in CO3^2- is +4. Each oxygen atom has an oxidation number of -2, and since the overall charge of the carbonate ion is 2-, the carbon atom must have an oxidation number of +4 to balance the charge.

What are the oxidation numbers for each atom involved in the reaction 4ko2 and 2co2-2k2co3 and 3co2?

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 no of c in HCN and HNC IS?

In both HCN and HNC molecules, the oxidation number of carbon (C) is -3. This is because hydrogen (H) is almost always assigned an oxidation number of +1, and nitrogen (N) is usually assigned an oxidation number of -3. By assigning the oxidation numbers of H and N, we can then determine the oxidation number of C that makes the overall charge of the molecule neutral.
