* Reactant: Hydrogen peroxide (H₂O₂) is typically a liquid at room temperature.
* Products:
* Hydrogen (H₂) gas is produced.
* Oxygen (O₂) gas is also produced.
The reaction can be represented as follows:
2 H₂O₂ (l) → 2 H₂ (g) + O₂ (g)
Key Points:
* The decomposition of hydrogen peroxide is an endothermic reaction, meaning it requires heat to proceed.
* The reaction can be catalyzed by various substances, including manganese dioxide (MnO₂).
* The production of oxygen gas is what makes hydrogen peroxide a useful disinfectant and bleach.
