An element X burns in nitrogen to give a compound Y which on reaction with water gives a compound Z and a gas with a pungent smell. Z can be used during construction and white washing. When excess of CO_(2) is bubbled through Z, a compound P is formed which on heeating decomposes to give a compourless, odourless gas. identify X, Y, Z and P.

An element X burns in nitrogen to give a compound Y which on reaction

1.	An element X burns in nitrogen to give a compound Y which on reaction with water gives a compound Z and a gas with a pungent smell. Z can be used during construction and white washing. When excess of CO_(2) is bubbled through Z, a compound P is formed which on heeating decomposes to give a compourless, odourless gas. identify X, Y, Z and P.
Answer» <P>`X-Ca,Y-Ca_(3)N_(2),Z-Ca(OH)_(2),P-Ca(HCO_(3))_(2)` `X-Mg,Y-MgO,Z-Mg(OH)_(2),P-MgCO_(3)` `X-Ca,Y-Ca_(3)N_(2),Z-Ca(OH)_(2),P-CaCO_(3)` `X-Ca,Y-CaO,Z-Ca(OH)_(2),P-Ca(HCO_(3))_(2)` Solution :`underset((X))(3Ca)+N_(2)to underset((Y))(Ca_(3)N_(2))` `Ca_(3)N_(2)+6H_(2)O to underset((Z))(3Ca(OH)_(2))+underset(("gas with a pungent SMELL"))(2NH_(3))` `underset((Z))(Ca(OH)_(2))+underset("excess")(CO_(2)) to underset((P))(Ca(HCO_(3))_(2)` `underset((P))(Ca(HCO_(3))_(2))overset("HEAT")to CaCO_(3)+H_(2)O+CO_(2)`
