The oxidation number of carbonate ion (CO3) is -2. Each oxygen atom has an oxidation number of -2, and the sum of the oxidation numbers in the ion must equal the charge of the ion, which is -2.
The oxidation number for CO3 with a charge of -2 is 2.
The oxidation number of CO3 in NiCO3 is -2. In this compound, each oxygen atom has an oxidation number of -2, and since there are three oxygen atoms in CO3, the overall charge for the carbonate ion is -2. Therefore, the oxidation number of CO3 is -2 in NiCO3.
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.
Using the periodic table of elements you can find the oxidation number of NaHCO3. Na has a charge of +1 so it's oxidation number is +1. H has a charge of +1 so again, the oxidation number is +1. CO3(carbonate) has an oxidation number of -2. As far as I know, you can find the oxidation number for CO3 because all charges together come out to be zero. With Na and H adding up to 2, CO3 can be seen to be -2. Also, CO3 is -2 because it's Lewis structure is two electrons short from being complete.
The oxidation number of copper (Cu) in CuCO3 is +2. Oxygen typically has an oxidation number of -2, and the overall charge of the carbonate ion (CO3) is -2. Therefore, the oxidation number of copper is determined to be +2 in this compound.
The oxidation number for CO3 with a charge of -2 is 2.

The oxidation number of carbon (C) in CO3^2- is +4. This is because the sum of the oxidation numbers in the carbonate ion must equal its charge of -2, and oxygen is typically assigned an oxidation number of -2.
The oxidation number of each copper (Cu) atom in CuCO3 is +2. The oxidation number of the oxygen (O) atoms in the carbonate ion (CO3) is -2, and the overall charge of the carbonate ion is -2.
The oxidation number of carbon in carbonate (CO3^2-) is +4. Oxygen has an oxidation number of -2, so the three oxygen atoms contribute a total of -6. To balance the charge of -2 for the entire carbonate ion, the carbon atom must have an oxidation number of +4.
The oxidation number of carbon in carbonate (CO3^2-) is +4. In the carbonate ion, each oxygen atom has an oxidation number of -2, so the overall charge of the ion is -2. This means the oxidation number of carbon must be +4 to balance the charges in the compound.
The oxidation number of Fe in FeCO3 is +2. This is because the overall charge of the carbonate ion (CO3^2-) is -2, so the iron (Fe) must have an oxidation state of +2 to balance the charge of the compound.
if iron has an oxidation state of +2 K2(CO3) + FeBr2 ---> KBr + FeCO3 if iron has an oxidation state of +3 3K2(CO3) + 2FeBr3 ----> 6KBr + Fe2(CO3)3
