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.

1.	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.
Answer» Solution :(i) L = Copper(II) nitrate, M = NITROGEN (IV) oxide, N = Hydrogen SULPHIDE (ii) `2Cu(NO_(3))_(2)OVERSET("Heat")to2CuO+4NO_(2)+O_(2)` (iii) `Cu(NO_(3))_(2)+H_(2)StoCuS+2HNO_(3)`
