Yes.
Barium oxide is formed from barium and oxygen.
Because it decomposes to form carbon dioxide and barium oxide.
No, BaCO3 is a carbonate from the CO3 part of the compund
BaCO3(s) → BaO(s) + CO2(g)
The forumula for Barium Carbonate is BaCO3
Barium Oxide
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.
Barium can form both barium peroxide (BaO2) and barium oxide (BaO) depending on the conditions. Barium peroxide is formed when barium reacts with oxygen in excess. Barium oxide is commonly formed when barium reacts with oxygen in limited supply or at high temperatures.
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
Yes, there will be a gelatinous white precipitate of barium carbonate formed when barium acetate and sodium carbonate are mixed together in aqueous solution. This is due to the precipitation reaction that forms an insoluble salt, barium carbonate.
The ionic compound name for BaCO3 is barium carbonate. Barium is the cation with a 2+ charge, while carbonate is the anion with a 2- charge.
