Name:
A greenish yellow gas with pungent smell.

A greenish yellow gas reacts with an alkin metal hydroxide to form a halate which can be used in fireworks and saftey matches. The gas and the halate are

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?

Select from the list the gas that matches the description given in each case [Hydrogen , Nitrogen,Ammonia,Nitrogen dioxide, Chlorine] A greenish yellow gas that turns moist starch iodide paper blue black.

Select from the list the gas that matches the description given in each case : [Methane , Hydrogen, Nitrogen , Ammonia , Nitrogen dioxide , Chlorine] A greenish yellow gas that turns moist starch iodide paper blue black.

Choose the letter corresponding to the correct answer from - A: NO_(2),B:NO,C:N_(2),D:N_(2)O . The gas obtained when - A greenish yellow gas reacts with excess ammonia.

On reaction with excess ammonia, chlorine gas gives nitrogen gas along with a compound X. X reacts with Ca(OH)_2 and gives Y, a colorless gas with pungent smell. Y on reaction with excess of chlorine gives Z and HCl. What is Z?

Identify the salt R from the observation Salt R is black in colour. On reacting with concentrated HCl, it liberates a pungent greenish yellow gas which turns moist starch iodide paper blue black.

An element X burns in nitrogen to give a compound Y which on reaction with water gives a compound Z and a gas with a pungent smell. Z can be used during construction and white washing. When excess of CO_(2) is bubbled through Z, a compound P is formed which on heeating decomposes to give a compourless, odourless gas. identify X, Y, Z and P.

When F_2 is passed into a solution of mineral acid X, a greenish yellow gas Y is formed. Which on treating With slaked time forms "Z". When Red litmus is kept in contact with Z, it changes into

Greenish yellow gas which turns starch iodide paper black.
