Question

The action of conc H2SO4 on urea produces a white crystalline solid. (X) which act as monobasic acid.
The number of moles of nitrogen gas liberated when (X) react with NaNO2 and HCl according to
balanced chemical reaction is

Answer 1

Answer:

NH2CONH2 (urea) react with H2SO4 forming (x) {H3NO3S}

X contains one ionisation H{since x is a monobasic acid}

Thus x contains free - NH2 as well as free - So3H(Nano2 +HCL) convert free - NH2 into free - OH group liberating N2

Nano2 +HCL convert into HNo2 +NaCl
