Vedclass · Answer

(B) The thermal decomposition reactions are as follows:$(NH_4)_2Cr_2O_7 \xrightarrow{\Delta} Cr_2O_3 + N_2 \uparrow + 4H_2O$$Ba(N_3)_2 \xrightarrow{\Delta} Ba + 3N_2$$2NaNO_3 \xrightarrow{\Delta} 2NaNO_2 + O_2$From the above reactions, it is clear that ammonium dichromate $(ii)$ and barium azide $(iii)$ liberate dinitrogen gas upon heating, whereas sodium nitrate $(i)$ liberates dioxygen gas.Therefore, the correct option is $ii$ and $iii$ only.

Which of the following, when subjected to thermal decomposition, will liberate dinitrogen?
$(i)$ Sodium nitrate
$(ii)$ Ammonium dichromate
$(iii)$ Barium azide
