A gas , that relights glowing splinter , is

The nitrate which when heated gives off a gas (or) a mixture of gases which cannot relight a glowing splinter is

The nitrate which when heated gives off a gas or a mixture of gases which cannot relight a glowing splinter is:

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.

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.

When a white crystalline solid is heated strongly, it decomposes to gives a yellow residue, reddish brown gas, and rekindles a glowing splinter. Identify the reddish - brown gas.
