A colourless crystalline chloride, when warmed with solid NaOH, gave ammonia gas. Identify the salt.

A colourless gas X forms a brown coloured gas when mixed with air. The gas X is

A colourless crystalline salt, on being heated, gives a coloured gas with a pungent smell. On being passed through an AgNO_(3) solution, this gas forms a white precipitate insoluble in HNO_(3) but readily soluble in an NH_(3) solution. Which of the following reaction can lead to the above observation?

A Colorless solid A liberates a brown gas B on acidification, a colorless alkaline gas (C) on treatment with NaOH and a colorless non-reactive gas D on heating. If heating of the solid is continued, it completely disappears. The compound A is

A solution of a colourles salt H on boiling with excess of NaOH produces a non-flammable gas and the evolution of gas ceases after sometime. Upon addition of Zn dust to the same solution, the evolution of gas restarts. The colourless salt (S) 'H' is (are)

When silver chloride is treated with aqueous ammonia, the complex obtained is

A Colorless solid A liberates a brown gas B on acidification, a colorless alkaline gas (C) on treatment with NaOH and a colorless non-reactive gas D on heating. If heating of the solid is continued, it completely disappears. Which one of the following is correct?

A solution of colourless salt on boiling with excess NaOH produces a non-flammable gas. The gas evolution ceases after sometime upon addition of Zn dust to the same solution, the gas evolution restarts. The colourless salt (s) is (are).

A white sublimable solid, when boiled with an NaOH solution, gives a colourless gas that turns nessler's reagent brown. The solid on being heated with solid K_(2)Cr_(2)O_(7) and concentrated H_(2)SO_(4) , gives red brown vapours. The white solid can be:

On heating lead (II) nitrate gives a brown gas " A". The gas " A" on cooling changes to colourless solid "B" . Solid B on heating with NO changes to a blue solid 'C . Identify ' A', 'B' and' C and also write reactions involved and draw the structures of 'B' and 'C' .
