The gas which rekindles a glowing splinter.

A white crystalline solid (A) on boiling with caustic soda solution gave a gas (B) which when passed through an alkaline solution of K_(2) [HgI_(4)] gave a brown precipitate. The substance (A) on heating gave a gas (X) which rekindled a glowing splinter but does not give brown fumes with nitric oxide. The gas (X) is:

A blue crytalline solid 'X' on heating gave a reddish brown gas 'Y' a gas which relits a glowing splint and a residue which is black .identity X and Y , and write the equation for the action of heat on X.

The action of heat on the blue crystalline solid L gives a reddish brown gas M, a gas which re-lights a glowing splint and leaves a black residue. When gas N, which has a rotten egg smell, is passed through a solution of La black precipitate is formed. Write the equation for the action of heat on L.

The action of heat on the blue crystalline solid L gives a reddish brown gas M, a gas which relights a glowing splint and leaves a black residue. When gas N, which has a rotten egg smell, is passed through a solution of L, a black precipitate is formed. (i) Identity L, M and N (name or formula) (ii) Write the equation for the action of heat of L. (iii) Write the equation for the reaction between the solution of L and the gas N.

What happens when a glowing splinter is introuduced in a jar containing oxygen ?

The gas which reacts with haemoglobin in blood is :

The following materials are provided - solutions of cobalt chloride, ammonia, potassium permanganate, lime water, starch-iodide, sodium hydroxide, lead acetate, potassium iodide. Also provided are litmus and filter papers, glowing splinters and glass rods. Using the above how would you distinguish between: a] a neutral, acidic and a basic gas b] oxygen and hydrogen gas. c] carbon dioxide and sulphur dioxide gas d] chlorine and hydrogen chloride gas e) hydrogen sulphide and nitrogen dioxide gas f] ammonia and carbon dioxide gas g] zinc carbonate and potassium nitrate h] hydrated copper sulphate and anhydrous copper sulphate i] ammonium sulphate and sodium sulphate.

The gas which is present both in producer gas and in water gas is …………….
