1.	The reaction between urea and nitrous acid producesA. `N_(2)O`B. `N_(2)`C. `NO_(2)`D. `NH_(3)`
Answer» Correct Answer - 2 Nitrogen may be obtained in the elementary form by heating urea with nitrous acid. `underset("Urea")(H_(2)NCONH_(2))+2NHO_(2)rarr2N_(2)+CO_(2)+3H_(2)O` Nitrous acid is unstable and is always prepared in situ by the action of dilute sulphuric acid on sodium or potassium nitrite.
