(Given: Molar mass of $Ag$ is $108\, g \,mol ^{-1}$ and that of $Cl$ is $35.5 \,g\, mol ^{-1}$ )
$(II)$ (figure)
$(III)\, CH_3-N=CH_2$
$(IV)\, C_2H_5-CH=N-OH$
$(i)$ $6C(s) + 3{H_2}(g) \to {C_6}{H_6}(l);\,\Delta H = + 45.9\,kJ$
$(ii)$ ${H_2}(g) + \frac{1}{2}{O_2}(g) \to {H_2}O(l);\,\Delta H = - 285.9\,kJ$
$(iii)$ $C(s) + {O_2}(g) \to C{O_2}(g);\,\Delta H = - 393.5\,kJ$
........$kJ$
