A sample of ${\mathrm{NH}}_4{\mathrm{NO}}_3$ decomposes at an unspecified temperature, and the resulting gases are collected over water at $20^{?}\mathrm{C}$. Without completing a calculation, predict whethe- the volume of gases collected can be used to distinguish between the two reaction pathways. Explain your answer. The gas produced during the thermal decomposition of $0.256\mathrm{g}$ of ${\mathrm{NH}}_4{\mathrm{NO}}_3$ displaces $79\mathrm{mL}$ of water at $20^{?}\mathrm{C}$ and 760 torr of atmospheric pressure. Is the gas ${\mathrm{N}}_2\mathrm{O}$ or a mixture of ${\mathrm{N}}_2$ and ${\mathrm{O}}_2$ ?
