- Definition of Zn3N2:
Zn3N2, also known as zinc nitride, is a chemical compound composed of 3 zinc atoms and 2 nitrogen atoms. In English, we call it “zinc nitride”. The atomic mass of Zn3N2 is 243.38 with the atomic mass of zinc being 65.38 and nitrogen being 14. Its molecular structure consists of 3 zinc ions (Zn2+) and 2 nitrogen ions (N3-).
- Properties of Zn3N2:
Zn3N2 is a black solid with no distinct smell. It has a neutral pH level. Chemically, Zn3N2 is very unstable in humid air and easily converts to zinc oxide and nitrogen.
- Common chemical equations involving Zn3N2:
Zn3N2 can react with metals like Cu, Ag to form Cu3N2, Ag3N. Zn3N2 can also react with acids such as HCl, H2SO4 to form ZnCl2, ZnSO4 and NH4Cl. Zn3N2 can react with nonmetals like O2, S to form ZnO, ZnS. Zn3N2 does not typically react with salts.
- Synthesis of Zn3N2:
In the lab, Zn3N2 can be synthesized through the reaction between zinc and ammonia. Industrially, Zn3N2 is often produced through the reaction between zinc and nitrogen at high temperatures.
