Firstly, I apologize, but it seems like the information you provided is not accurate. The formula Ba2CO4 does not represent any well-known chemical substance.
However, we can discuss the formula BaCO3, also known as Barium Carbonate. It is a salt of barium and carbonic acid, being a solid, white, and odorless substance. Its molar mass is 197.34 g/mol. It consists of one barium ion (Ba2+) and one carbonate ion (CO3 2-).
In terms of chemical properties, Barium Carbonate is insoluble in water but soluble in acid. It can react with strong acid to form the corresponding barium salt and release CO2 gas.
Barium Carbonate is usually synthesized by the reaction between Barium Sulfide and Carbon Dioxide water. This reaction is represented by the equation: BaS + H2O + CO2 -> BaCO3 + H2S.
Barium Carbonate is also used in the production of ceramics, glass, paint, paper, electrolyte fluids, and many other industrial products. I hope that you understand more about Barium Carbonate after this lecture.
