Question

Gas ‘X’ is produced by thermal decomposition of Ammonium Dichromate. ‘X’ gas when reacts with hydrogen gas under appropriate condition produced gas ‘Y’ which on reaction with CuSO4 solution forms deep blue complex’Z’. Identify ‘X’, ‘Y’ and ‘Z’ .Write the reaction involved ?

Answer 1

Explanation:

Ammonium dichromate decomposes on heating to produce nitrogen gas water vapour (gaseous due to the temperature of the reaction), and solid chromium(III) oxide. Was this answer helpful?

Answer 2

Answer:

X=N2,Y=MG3N2,Z=NH3

Explanation:

A gas X is formed by heating ammonium nitrite.

NH4NO2-N2+2H2O

Thermal decomposition of ammonium nitrate gives n2

so,X=N2

Mg metal burns X to form Y

3MG+N2-MG3N2

Magnesium reacts with n2 and form mg3n2

so,Y=MG3N2

Y reacts with water to form a gas which turn Z red litmus blue

MG3N2+H20-MG(OH)2+NH3

SO,Z=NH3.
