An oragne colour solid (A) on heating gives a colourless gas (B) and colourless vapours (C) which on condensatio gives a colourless neutral liquid and a green residuce (D) which is a metal oxide. Gas - B gives a pungent odoured gas when reacts with hydrogen catalytically. Neutral liquid above formed converts anhydrous copper sulphate to blue Neutral liquid formed in the reaction is ........

1.	An oragne colour solid (A) on heating gives a colourless gas (B) and colourless vapours (C) which on condensatio gives a colourless neutral liquid and a green residuce (D) which is a metal oxide. Gas - B gives a pungent odoured gas when reacts with hydrogen catalytically. Neutral liquid above formed converts anhydrous copper sulphate to blue Neutral liquid formed in the reaction is ........
Answer» `NH_(4)OH` `H_(2)O` `H_(2)O_2` NONE Solution :`underset("orange")Aoverset(Delta)rarrunderset((a))(B+C)("Vapour")overset("Condensation")rarr"Liquid"+underset("green")D` `underset((A))underset("Orange")((NH_4)_2)Cr_2O_7overset(Delta)rarrunderset((B))underset((a))(N_2)+underset((C))underset((a))(4H_(2)O)+Cr_(2)O_(3)rarrunderset("Liquid")underset("Neutral")underset(uarr)(N_(2_((g))))+H_(2)O_((l))+underset((D))underset("green")(Cr_(2)O_3)` Natural liquid is water `(H_2O)`
