Barium Carbonate is BaCO3 and the oxidation numbers are +2 for barium, +4 for carbon and -2 for each oxygen.
The oxidation number of barium is +2.

The forumula for Barium Carbonate is BaCO3
Magnesium and carbonate are divalent.
barium carbonate is a white crystals that it is an insoluble salts.
The oxidation number of barium is +2.
The oxidation number of barium in BaO2 is 2.
The answer, barium II carbonate is wrong for the formula BaCO3 because barium has only one possible charge.

BA is in the group2. It generally shows +2 oxidation state.
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.

+2 for Mg, +4 for C, -2 for each O in MgCO3
Barium sulfate is insoluble in water, while barium carbonate will dissolve. As barium carbonate dissolves in water, it dissociates, and the barium ions are freed. The barium ions are toxic, and that is the crux of the issue.
Thallium has an oxidation number of +1. Therefore, the formula for thallium carbonate would be Tl2CO3.
When barium nitrate and potassium carbonate are mixed, barium carbonate precipitates out of the solution. This is due to the insolubility of barium carbonate in water compared to barium nitrate and potassium carbonate.
The chemical formula for Barium Carbonate is BaCO3
