1.	NaNO_(3)overset(500^(@)C)rarrA+X_((g)) , A+NH_(2)CONH_(2)+H^(+)rarrY_((g))+z_((g))+H_(2)O. What are the gases X, Y and Z ?
Answer» Solution :`2NaNO_(3)overset(500^(@)C)rarr2NaNO_(2)+O_(2)` `2NaNO_(2)+NH_(2)CONH_(2)+2H^(+)rarr2N_(2)+CO_(2)+3H_(2)O+2Na^(+)` X is `O_(2)` , Y is `N_(2)` and Z is `CO_(2)`
