1.	The action of heat on the blue crystalline solid X,gives a reddish brown gas Y, a gas which re-lights a glowing splint and leaves a black residue . when gas Z, which has a rotten egg smell , is passed through a solution of X , a black ppt. is formed.(a) Identify X,Y,Z.(b)Write equation for action of heat on X.(c)Write equation b/w solution of X and gas Z.
Answer» I)X-copper nitrate Cu(NO3)2Y-nitrogen dioxideZ-hydrogen sulphide2)2Cu(NO3)2+heat--->2CuO+4NO2+O23)Cu(NO3)2+H2S---->CuS+2HNO3 what is this '>' ?
