Barium Selenide ---> Ba2+Se2- ---> BaSe
The chemical formula of barium phosphate is Ba3(PO4)2.
An ionic compound, Barium selenide or BaSe is formed, with the ions Ba2+ and Se2-.
Ba3N2 Nitride has an oxidation state of -3 ( N3- ) and Barium has an oxidation state of +2, or Ba2+. To obtain the formula, the charges are balanced out and the result is an oxidation state of 0. The formal is Ba3N2.
Ba2+(aq) + SO42-(aq) --> BaSO4(s) The other ions, Cu2+ and Cl-, don't react (tribune ions).
Ba2(SO4)2
Barium Oxide is BaO.Ba+2 is Barium positive ion (anion).
BaI2 is formed from Ba2+ and 2 I-
Ba2+
This is not an equation but the chemical symbol of the cation: Ba2+.
Ba2+
Formula: Ba2+
I believe that would be Barium nitrate or Ba(NO3)2
Ba2+ and Cl-.
