Question
Simple question but make me confuse:
can we produce urea from Nitrogen gas (N2) + H2SO4 ??
Thx for u all..  

Answer
Many cheap fertilizer companies produce Urea Fertilizer (CO(NH2)2) by mixing Ammonia and Carbon Dioxide.

It would be hard to try this at home.  Ammonia is highly volatile.  Factories are needed to do it successfully.  You just can't do it in a kitchen or in the garage.  It takes a laboratory and heavy duty equipment.  But yes, it can be done.
