The correct answer is: $\left(\mathrm{NH}_{4}\right)_{2}\left(\mathrm{C}_{2} \mathrm{O}_{4}\right)$
$\left(\mathrm{NH}_{4}\right)_{2} \mathrm{Cr}_{2} \mathrm{O}_{7} \longrightarrow \mathrm{N}_{2}+\mathrm{Cr}_{2} \mathrm{O}_{3}+\mathrm{H}_{2} \mathrm{O}$
$2 \mathrm{NaN}_{3} \longrightarrow 2 \mathrm{Na}+3 \mathrm{~N}_{2}$
$\mathrm{NH}_{4} \mathrm{NO}_{2} \longrightarrow \mathrm{N}_{2}+\mathrm{H}_{2} \mathrm{O}$
$\left(\mathrm{NH}_{4}\right)_{2} \mathrm{C}_{2} \mathrm{O}_{4} \longrightarrow 2 \mathrm{NH}_{3}+\mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4}$
