carbon suboxide C3O2 OCCCO. The oxygen atoms have an oxidation number of -2 same as normal, (only when O is bonded to O as in peroxides is the oxidation number not -2)
Carbon atoms oxidation number is +2.Hydrogen's oxidation number is +1.Oxygen's oxidation number is -2.
I believe K2CO3.
Carbon has an oxidation number of +4 in both carbonate and bicarbonate. Oxygen as usual has an oxidation number of -2, and hydrogen has an oxidation number of +1. Therefore, the ion CO3-2 has six negative charges from oxygen partly balanced by four positive changes from carbon for a net of -2, and HCO3-1 has six negative charges from oxygen partly balanced by one positive from hydrogen and needs for plus four from carbon for an overall value of -1.
Carbonate is CO32- ion and the oxidation numbers are +4 for carbon and -2 for each oxygen.
The oxidation number of oxygen is -2 and there are two oxygen atoms, so the total oxidation number for the oxygen in CO2 is -4. This means that the oxidation number for the carbon atom is +4, because the compound has to have a 0 oxidation number.

Sodium is always 1+, oxygen in this case is 2-. The sum of all of these atoms' oxidation numbers is -4. Therefore, since the compound in neutral carbon must have a +4 oxidation number.
Carbon is directly bonded with two hydrogen atoms and with an oxygen atom. All other elements are more electronegative than carbon. Therefore carbon has oxidation number +4.
The oxidation number of oxygen is -2 in most of its compounds
There are three elements, carbon, oxygen and hydrogen. Carbon's oxidation number is -4, each hydrogen is +1 and oxygen is +2.
+4 oxygen has an oxidation of -2, so do 3 times -2=-6, i believe Ca is a +2 and you must get the numbers to equal 0. so the answer is a +4
-2 for each Oxygen +4 for each Carbon
Barium Carbonate is BaCO3 and the oxidation numbers are +2 for barium, +4 for carbon and -2 for each oxygen.
