A metal A on heating in nitrogen gas gives compound B. B on treatment with H2O gives a colourless gas which when passed through CuSO4 solution gives a dark blue-violet coloured solution. A and B respectively, are:
  1. Na and NaNO3
  2. Na and Mg3N2
  3. Mg and Mg3N2
  4. Mg and MgNO32

Solution

Magnesium nitride ceramic powder can be used in the preparation of other nitride compound with high hardness, high thermal conductivity, corrosion resistance, wear resistance and high temperature resistance properties; It can be used for preparation of special ceramic material and for special alloy blowing agent
