The chemical name for Ba2OH- is barium hydroxide. It is composed of a barium ion (Ba2+) and a hydroxide ion (OH-).
The reaction between SO42- and Ba2+ forms BaSO4. The chemical formula is BaSO4.
The chemical name of Ba2P3 is barium phosphide. It is composed of two barium ions (Ba2+) and three phosphorous ions (P3-).
If you think to barium phosphide the correct formula is Ba3P2.
When Ba(OH)2 dissociates in water, it forms Ba2+ ions and 2 OH- ions. The Ba2+ ion carries a double positive charge and is a cation, while the OH- ions are hydroxide ions and carry a single negative charge as anions.
The chemical name for hydrated lime is Calcium hydroxide The chemical formula is Ca(OH)2.
The reaction between SO42- and Ba2+ forms BaSO4. The chemical formula is BaSO4.
Ba2+
When barium ion is added to a hydroxide ion, the two opposite charges attract each other to form barium hydroxide Ba2+ + OH------>Ba(OH)2.
The chemical name of Ba2P3 is barium phosphide. It is composed of two barium ions (Ba2+) and three phosphorous ions (P3-).
If you think to barium phosphide the correct formula is Ba3P2.
When Ba(OH)2 dissociates in water, it forms Ba2+ ions and 2 OH- ions. The Ba2+ ion carries a double positive charge and is a cation, while the OH- ions are hydroxide ions and carry a single negative charge as anions.
The combination of Ba2+ and PO43- ions forms the compound barium phosphate, which has the chemical formula Ba3(PO4)2. In this compound, two phosphate ions (PO43-) are needed to balance the charge of three barium ions (Ba2+).
The chemical name for hydrated lime is Calcium hydroxide The chemical formula is Ca(OH)2.
Barium hydroxide is composed of one barium ion (Ba2+) and two hydroxide ions (OH-), resulting in the chemical formula Ba(OH)2.
When combining atoms or groups to form a compound, look at their charges to determine how many of each you need in order for the positive and negative charges to cancel out (form a neural compound). Since Ba has a +2 charge and OH has a -1 charge, you need two OH groups to cancel out one Ba atom. In other words, make it so that +2 + -2 = 0. Here's the overall equation:Ba2+ + 2OH- --> Ba(OH)2
Ba(OH)2 is slightly soluble in water and will partially dissociate into Ba2+ and hydroxide ions.
You're expressing those two reactants as ions. The chemical equation for the reaction between barium and nitrogen is: 3Ba + N2 --> Ba3N2. Or, if you like, the net ionic equation for the formation of the insoluble precipitate barium nitride is: 3Ba+2 + 2N-3 --> Ba3N2.
