How is nitrogen prepared in the laboratory? Write the chemical equations of the reactions involved
Nitrogen is prepared in the laboratory by heating an equimolar aqueous solution of ammonium chloride and sodium nitrite. The ammonium nitrite formed as a result of double decomposition reaction, decomposes to form dinitrogen. NH4NO2(aq)Ammonium nitrate Δ→N2(g)Nitrogen+2H2O(l).
