Vedclass · Answer

(C) The thermal decomposition of metal nitrates follows specific patterns based on the reactivity of the metal.$1$. For alkali metal nitrates like $NaNO_3$,heating below $500 \ ^\circ C$ yields the metal nitrite and oxygen gas: $NaNO_3 \xrightarrow{$2$. For heavy metal nitrates like $Cu(NO_3)_2$,$Hg(NO_3)_2$,and $AgNO_3$,heating results in the formation of the metal oxide (or metal),nitrogen dioxide $(NO_2)$,and oxygen gas:$Cu(NO_3)_2 \xrightarrow{\Delta} CuO + 2NO_2 + \frac{1}{2} O_2$$Hg(NO_3)_2 \xrightarrow{\Delta} Hg + 2NO_2 + O_2$$AgNO_3 \xrightarrow{\Delta} Ag + NO_2 + \frac{1}{2} O_2$Therefore,$NaNO_3$ does not produce $NO_2$ upon heating.

Nitrogen dioxide $(NO_2)$ cannot be obtained from the thermal decomposition of which of the following?
