Question

On heating ${\mathrm{NaNO}}_3$ gives-

Answer 1

Heating ${\mathrm{NaNO}}_3$:

• Decomposition reactions are reactions in which chemical species break up into simpler parts.
• On heating, sodium nitrate (${\mathrm{NaNO}}_3$) undergoes a decomposition reaction and gives Sodium nitrite (${\mathrm{NaNO}}_2$) and Oxygen (${\mathrm{O}}_2$) as its product.

$\underset{\mathrm{Sodium}\mathrm{nitrate}}{2{\mathrm{NaNO}}_3\left(\mathrm{s}\right)}\underset{∆}{\to }\underset{\mathrm{Sodium}\mathrm{nitrite}}{2{\mathrm{NaNO}}_2\left(\mathrm{s}\right)}+\underset{\mathrm{Oxygen}}{{\mathrm{O}}_2\left(\mathrm{g}\right)}$

Therefore, On heating ${\mathrm{NaNO}}_3$ gives Sodium nitrite (${\mathrm{NaNO}}_2$) and Oxygen (${\mathrm{O}}_2$).
