+1 for each Na
-2 for S
The oxidation number of sulfur (S) in Na2S is -2. In Na2S, there are two Na+ ions with a charge of +1 each, making a total of +2. Since the compound is neutral, the oxidation number of sulfur must be -2 to balance out the charges.
The chemical name for the compound with the formula Na2S is sodium sulfide. In this compound, sodium (Na) is in the +1 oxidation state, and sulfur (S) is in the -2 oxidation state. The subscript "2" in the formula indicates that there are two sodium atoms for every one sulfur atom in the compound.
The balanced chemical equation for CdBr2 + Na2S is: CdBr2 + Na2S → CdS + 2NaBr
The oxidation number of acetate (CH3COO-) is -1. The carbon atom has an oxidation number of +3, each hydrogen atom has an oxidation number of +1, and the oxygen atoms have an oxidation number of -2.
The oxidation number of each hydrogen in H2CO2 is +1, while the oxidation number of each carbon in CO2 is +4. This is because hydrogen usually has an oxidation number of +1, and oxygen usually has an oxidation number of -2.
