Answer:The oxidation number of the carbons + the oxidation numbers of the oxygens must equal -2. Carbons + (-8) = -2 so the oxidation number of the carbons must be +6. Since there are 2 carbon atoms each must contribute +3 each. What is the oxidation number of S in Na2S2O3?

Explanation:

The oxidation state of Oxygen is -2 and that of Calcium is +2. There are four oxygen atoms which amounts to -8 charge. This leaves a charge of +6 on Carbon
