We can find this in bleaching powder. Chlorine shows +1 oxidation number.
Oxidation state of elements in Sodium Oxide (Na2O) :
> Sodium = 1
> Oxygen = -2
+1 for Na
-2 for O
+4 for C
Carbonate is CO32- ion and the oxidation numbers are +4 for carbon and -2 for each oxygen.
Each of the two sodium atoms in the formula for sodium oxide has an oxidation number of +1, and the oxygen atom has an oxidation number of -2.
+4 for carbon
This compound is sodium thiosulphate. S represents +6 oxidation number.
Tl2CO3
Na2C03 Oxidation number of Na = + 1 Oxidation number of O=-2, Oxidation number of C=2x1+x+3(-2)=0 so x=4
Carbonate is CO32- ion and the oxidation numbers are +4 for carbon and -2 for each oxygen.
Each of the two sodium atoms in the formula for sodium oxide has an oxidation number of +1, and the oxygen atom has an oxidation number of -2.
Magnesium and carbonate are divalent.
Barium Carbonate is BaCO3 and the oxidation numbers are +2 for barium, +4 for carbon and -2 for each oxygen.
+4 for carbon
This compound is sodium thiosulphate. S represents +6 oxidation number.

Tl2CO3
nickel sulfate + sodium carbonate -> sodium sulfate + nickel carbonate
No. Sodium carbonate is Na2CO3. Sodium bicarbonate is NaHCO3. Sodium carbonate is a stronger base.
It contains sodium hypochloride. Chlorine shows +1 as the oxidation number.
