Describe tests to identify the gases: (a) ammonia, ( NH_3 ), using damp red litmus paper (b) carbon dioxide, ( CO_2 ), using limewater (c) chlorine, ( Cl_2 ), using damp litmus paper (d) hydrogen, ( H_2 ), using a lighted splint (e) oxygen, ( O_2 ), using a glowing splint (f) sulfur dioxide, ( SO_2 ), using acidified aqueous potassium manganate(VII)

State the symbol equation for the production of ammonia in the Haber process, ( N_2(g) + 3H_2(g) ightleftharpoons 2NH_3(g) )
