1.	An organic solid (A) on heating gives a green residue (B), a colourless gas (C) and water vapours. The dry gas (C) passing over heated Mg gave a white solid (D). (D) on reaction with water give a gas (E) which formed dense white fumes with HCl. Identify (A) to (E) and give the reactions involved.
Answer» A = (NH₄)₂Cr₂O₇ B = Cr₂O₃ C = N₂ D = Mg₃N₂ E = NH₃
