Which of the following nitrate will give ${\mathrm{N}}_2\mathrm{O}$ on heating?

${\mathrm{NH}}_4{\mathrm{NO}}_3$ will give ${\mathrm{N}}_2\mathrm{O}$ on heating

Ammonium chloride undergoes dissociation when heated, producing products like ${{\mathrm{NH}}_3}_{ }$and $\mathrm{HCl}$. When heated, ammonium chloride undergoes sublimation, turning from a solid to a gas. Molecules like ammonia and hydrogen chloride can be found in the gas.

${\mathrm{NH}}_4{\mathrm{NO}}_3\stackrel{\mathrm{\Delta }}{\to }{\mathrm{N}}_2\mathrm{O}+{\mathrm{H}}_2\mathrm{O}$

Hence, option A is correct.”
