An orange soloid ( X ) on heating gives green residue ( Y ), water vapour and a colourless gas ( Z ). Thegas , Z , in dry conditions is passed over heated Magnesium to give a solid ( W ) which gives white fumes with HCl.
Identify X, Y, Z, W
also can u post more of such questions. rates assured.

THE COMPOUND X IS AMMONIUM DICHROMATE,NOT POTTASSIUM DICHROMATE WHICH I EARLIER WRITTEN.......(SAHIL MADAAN IS RIGHT)
AMMONIUM DICHROMATE ON HEATING FORMS ::
GREEN RESIDUE(CR2O3) ----Y
NITROGEN (N2,COLOURLESS GAS)------Z
MAGNESIUM NITRIDE. -----W
SAHIL IS RIGHT THANKS.....
HP U GOT IT.
