Question

Write an equation for the following reaction: Action of heat on potassium nitrate.

Answer 1

• A decomposition reaction is a reaction in which the chemical compound break into simpler parts.
• $\underset{\mathrm{potassium}\mathrm{nitrate}}{\underset{}{2{\mathrm{KNO}}_3\left(\mathrm{s}\right)}}\to \underset{\mathrm{potassium}\mathrm{nitrite}}{\underset{}{2{\mathrm{KNO}}_2\left(\mathrm{s}\right)}}+{\mathrm{O}}_2\left(\mathrm{g}\right)$
• When potassium nitrate is heated it decomposes into potassium nitrite and oxygen.
