Answer 1

Answer:

Nacl HNO2....................

Answer 2

In the laboratory method of preparation of nitrogen from Nh4Cl and NaNo3the other by-products of nitrogen formed is NaCl. (Option C)

• Nitrogen is prepared in the laboratory by heating on equimolar aqueous solution of ammonium chloride and sodium nitrite.
• Then ammonium nitrite and sodium chloride are formed.
• The ammonium nitrite formed as a result of double decomposition reaction and decomposes to form dinitrogen.
• The reaction is as follows: $NH_{4} Cl (aq) + NaNO_{2} (aq) = NH_{4} NO_{2} (aq) + NaCl(aq)$
• $NH_{4}NO_{2} (aq)= N_{2} (g)+ 2H_{2} O(l)$
• From the above equations, we can see the other by product in Laboratory preparation of Nitrogen is NaCl.
