$(i)\,Al\,\xrightarrow{{{N_2}}}\,A$ $(ii)\,Al\,\xrightarrow{c}\,B$
Here $A$ and $B$ on hydrolysis respectively gives
- A$NH_3, \,C_2H_2$
- B$NO,\, CH_4$
- ✓$NH_3,\,CH_4$
- D$NO,\,C_2H_2$
Here $A$ and $B$ on hydrolysis respectively gives
$B = Al_ 4C_3 \xrightarrow{{{H_2}O}} CH_4$

$C ( s )+\frac{1}{2} O _{2}( g ) \rightarrow CO ( g )+100 \;kJ$
When coal of purity $60 \%$ is allowed to burn in presence of insufficient oxygen, $60 \%$ of carbon is converted into $'CO'$ and the remaining is converted into $'CO _{2}$$'$.
The heat generated when $0.6 \;kg$ of coal is burnt is
${\left[ {\begin{array}{*{20}{c}}
{\,\,\,\,\,\,O} \\
{\,\,\,\,\,\,||} \\
{C{H_2} = N = O}
\end{array}} \right]^\Theta }$
$[Br^-] = [Cl^-] = [CO_3^{2-} ] = [AsO_4^{3-}] = 0.1\,M$.
Which compound will precipitate with lowest $[Ag^+]$ ?
