Which of the following compounds, upon thermal decomposition, yields the same nitrogen-containing ga — p Block Elements Chemistry Question

💡 Solution & Explanation

Heating $NH_4NO_2$ yields $N_2$ gas. Similarly, the thermal decomposition of ammonium dichromate ($(NH_4)_2Cr_2O_7$) yields $N_2$ gas, $Cr_2O_3$, and $H_2O$. (Heating $NH_4NO_3$ yields $N_2O$, not $N_2$).
