MCQ
Which of the following on heating produces $NO_2$ ?
- A$NaNO_3$
- ✓$AgNO_3$
- C$NH_4NO_3$
- D$NH_4NO_2$
✓
Answer
Correct option: B.
$AgNO_3$
b
${\mathrm{AgNO}_{3} \longrightarrow \mathrm{Ag}+\frac{1}{2} \mathrm{O}_{2}+\mathrm{NO}_{2}}$
${\mathrm{AgNO}_{3} \longrightarrow \mathrm{Ag}+\frac{1}{2} \mathrm{O}_{2}+\mathrm{NO}_{2}}$
${2 \mathrm{NaNO}_{3} \frac{500\,^{\circ} \mathrm{C}}{800\,^{\circ} \mathrm{C}} 2 \mathrm{NaNO}_{2}+\mathrm{O}_{2}} $
${4 \mathrm{NaNO}_{3} \stackrel{800\,^{\circ} \mathrm{C}}{\longrightarrow} 2 \mathrm{Na}_{2} \mathrm{O}+5 \mathrm{O}_{2}+2 \mathrm{N}_{2}}$
