What is Ba3N2? Important knowledge about Ba3N2.

We are discussing the chemical compound Ba₃N₂, also known as Barium Nitride. In English, this compound is called Barium Nitride.

1.2. Ba₃N₂ consists of 3 Barium (Ba) atoms and 2 Nitrogen (N) atoms.
1.3. In a Ba₃N₂ molecule, the total atomic mass is 420.167 g/mol, where Ba accounts for 261.105 g/mol and N is 28.0134 g/mol.
1.4. Ba₃N₂ is an ionic compound, composed of Ba₂+ ions and N₃- ions. Barium can create Ba₂+ ions by giving away 2 electrons, and nitrogen can create N₃- ions by accepting 3 electrons.

2.1 Physical properties of Ba₃N₂:

• State: solid at room temperature
• Color: white
• Odor: none
• pH: not applicable to solids
  2.2 Chemical properties of Ba₃N₂:
• Reacts with water to form barium hydroxide and release ammonia gas
• Reacts with acid to form barium salt and release ammonia gas

3. Reactions of Ba₃N₂:

   • Example of reaction with metal: not suitable because Ba₃N₂ is a basic compound of the metal Barium
   • Example of reaction with acid:
     • Ba₃N₂ + 6HCl -> 3BaCl₂ + 2NH₃
     • Ba₃N₂ + 6HNO₃ -> 3Ba(NO₃)₂ + 2NH₃
     • Ba₃N₂ + 6H₂SO₄ -> 3BaSO₄ + 2NH₃
     • Ba₃N₂ + 6CH₃COOH -> 3Ba(CH₃COO)₂ + 2NH₃
     • Ba₃N₂ + 6H₃PO₄ -> 3Ba₃(PO₄)₂ + 2NH₃
   • Example of reaction with non-metal: not suitable because non-metals typically form compounds with nitrogen

4. Preparation of Ba₃N₂:

   • In the laboratory, Ba₃N₂ can be prepared by heating barium in a nitrogen atmosphere:
     • 3Ba + N₂ -> Ba₃N₂
   • In industry, Ba₃N₂ is produced in a similar manner as in the laboratory.
