Principle: In the laboratory, when nitrobenzene is heated with tin and HCl, aniline is formed.

i) Name the  gas collected in the jar.ii)  Write the balanced equation for the above preparation. Ltd. Write balanced chemical equations for the following:Water is added to calcium carbide. [Relatively molecular weight of Al4Cl3 = 144 ; Al(OH)3 = 78]. (v) How will you find that the jar is full of gas? The HCl gas is absorbed in deionized water resulting in chemically pure HCl.

As given, the mass of nitrogen and hydrogen such as, Number of a mole of nitrogen = 82.3514 = 5.88, Number of mole of hydrogen = 17.641 = 17.64, The ratio of their moles is 5.88: 17.641:3. So HCl gas undergoes back suction due to which the source of HCl will be affected.A) NaCl +H2SO4 ---> NaHSO4 +HClB) 2NaCl +H2SO4 ----> Na2SO4 +2HCl. Almost 90% of all known compounds are organic in nature.
