Answer 1

Various reactions of ammonia

(ⅰ ) ${\mathrm{N}}_2\left(\mathrm{g}\right)$ + $3{\mathrm{H}}_2\left(\mathrm{g}\right)$ $\to 2{\mathrm{NH}}_3\left(\mathrm{g}\right)$

(Nitrogen) (Hydrogen) (Ammonia)

(ⅱ) $$\begin{gathered} 8{\mathrm{NH}}_3\left(\mathrm{g}\right)+3{\mathrm{Cl}}_2\left(\mathrm{g}\right)\to 6{\mathrm{NH}}_4\mathrm{Cl}\left(\mathrm{g}\right)+{\mathrm{N}}_2\left(\mathrm{g}\right) \\ \left(\mathrm{Ammonia}\right)\left(\mathrm{Chlorine}\right)(\mathrm{Ammonium}\mathrm{chloride})\left(\mathrm{Nitrogen}\right) \end{gathered}$$

(ⅱⅰ) $$\begin{gathered} 3\mathrm{PbO}\left(\mathrm{s}\right)+2{\mathrm{NH}}_3\left(\mathrm{g}\right)\to 3{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)+{\mathrm{N}}_2\left(\mathrm{g}\right)+3\mathrm{Pb}\left(\mathrm{s}\right) \\ (\mathrm{Lead}\mathrm{oxide})\left(\mathrm{Ammonia}\right)\left(\mathrm{Water}\right)\left(\mathrm{Nitrogen}\right)\left(\mathrm{Lead}\right) \end{gathered}$$

(ⅳ) $$\begin{gathered} 4{\mathrm{NH}}_3\left(\mathrm{g}\right)+5{\mathrm{O}}_2\left(\mathrm{g}\right)\stackrel{\mathrm{Pt}}{\to }4\mathrm{NO}\left(\mathrm{g}\right)+6{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right) \\ \left(\mathrm{Ammonia}\right)\left(\mathrm{Oxygen}\right)excess\mathit{}(\mathrm{Nitric}\mathrm{oxide})\left(\mathrm{Water}\right) \end{gathered}$$

Hence reaction between Nitrogen and Hydrogen gives Ammonia, Ammonia and Chlorine give Ammonium chloride, and, Lead oxide with Ammonia gives Lead, Ammonium, and Sulphur dioxide gives Nitric oxide.
