sodium trioxonitrate (V) and ammonium chloride
sodium trioxonitrate (lll) and ammonium chloride
lead (ll) trioxonitrate (V) and copper turnings
potassium trioxonitrate (V) and copper turnings
Correct answer is B
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 a double decomposition reaction, decomposes to form nitrogen gas.
NH4Cl(aq)+NaNO2(aq)→NH4NO2(aq)+NaCl(aq)
NH4NO2(aq)→N2(g)+2H2O(l).
