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

The primary salt formed when H_2O_2 reacts with NaOH , is

Which salt is formed when NaOH reacts with Zn ?

In a gas phase reaction, 50 kg of nitrogen and 10 g of hydrogen are mixed to produce ammonia. Identify the limiting reagent. Calculate the maximum amount of ammonia produced.

Give the signs of , when ammonia gas gets adsorbed on chorcoal.

A white sublimable solid, when boiled with a NaOH solution, give a colour less gas thal turns Nessler's Teagent brown. The solid on being heated with solid K_(2)Cr_(2)O_(7) and conc. H_(2)SO_(4) , gives red brown vapours. The white solid can be

How do you count the following observations? a) Though alkaline potassium permanganate and acidic potassium permanganate both are used as oxidants, yet in the manufacture of benzoic acid from toluene we use alcoholic potassium permanganate as an oxidant. Why ? Write balanced redox equation for the reaction. b) When concentrated sulphuric acid is added to inorganic mixture containing chloride, we get colourless pungent smelling gas HCl, but if the mixture contains bromide then we get red vapour of bromine. Why ?

When a green solid P was heated it turned into a black solid Q and a colourless gas X was released. On passing gas X, over heated carbon and another colourless gas Y was formed. Gas Y burned in oxygen to reform gas X. Identify P and Q.

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 Gas 'B' in the above paragraph is ........
