Question

The products obtained on heating${\mathrm{LiNO}}_3$ will be ___________, ________ and __________.

• A. lithium oxide
• B. nitrogen dioxide and oxygen

Answer 1

Lithium nitrate

• The chemical name of ${\mathrm{LiNO}}_3$is lithium nitrate.
• The products obtained on heating ${\mathrm{LiNO}}_3$ will be lithium oxide $\left({\mathrm{Li}}_2\mathrm{O}\right)$ and nitrogen dioxide$\left({\mathrm{NO}}_2\right)$ and oxygen$\left({\mathrm{O}}_2\right)$.

Chemical reaction

• The chemical reaction is as follows:-

$4{\mathrm{LiNO}}_3\left(\mathrm{s}\right)\stackrel{∆}{\to }2{\mathrm{Li}}_2\mathrm{O}\left(\mathrm{s}\right)+4{\mathrm{NO}}_2\left(\mathrm{g}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)$

Hence, the products obtained on heating${\mathrm{LiNO}}_3$ will be lithium oxide $\left({\mathrm{Li}}_2\mathrm{O}\right)$ and nitrogen dioxide$\left({\mathrm{NO}}_2\right)$, and oxygen$\left({\mathrm{O}}_2\right)$.
