A colourless inorganic compound (A) imparts a green colour to the flame. Its solution gives a white ppt. (B) with H_(2)SO_(4). When heated with K_(2)Cr_(2)O_(7) and conc. H_(2)SO_(4), a brown red vapour/gas (C) is formed. The gas/ vapour when passed through aqueous NaOH solution, it turns into a yellow solution (D) which forms yellow precipitate (E) with CH_(3)COOH and (CH_(3)COO)_(2)Pb. with reference to above information, answe the following questions. Q. The liberated gas vapour (C) is:

1.	A colourless inorganic compound (A) imparts a green colour to the flame. Its solution gives a white ppt. (B) with H_(2)SO_(4). When heated with K_(2)Cr_(2)O_(7) and conc. H_(2)SO_(4), a brown red vapour/gas (C) is formed. The gas/ vapour when passed through aqueous NaOH solution, it turns into a yellow solution (D) which forms yellow precipitate (E) with CH_(3)COOH and (CH_(3)COO)_(2)Pb. with reference to above information, answe the following questions. Q. The liberated gas vapour (C) is:
