It looks like you're trying to understand the decomposition of hydrogen peroxide (H₂O₂) and perhaps some information related to a diagram or a flowchart that includes parts of the reaction labeled in boxes. However, since I'm unable to see the specific diagram or boxes you're referring to, I can still provide some general information about the hydrogen peroxide decomposition reaction.
The decomposition of hydrogen peroxide can be represented by the chemical equation:
\[ 2 , \text{H}_2\text{O}_2 (l) \rightarrow 2 , \text{H}_2\text{O} (l) + \text{O}_2 (g) \]
In this reaction:
- Reactants: 2 hydrogen peroxide molecules (labeled as H₂O₂).
- Products: 2 water molecules (H₂O) and 1 molecule of oxygen gas (O₂).
If you have parts of the reaction that are labeled, they might include:
- Reactants: H₂O₂
- Products: H₂O and O₂
- Catalyst: Sometimes, a catalyst like manganese dioxide (MnO₂) is used to accelerate the reaction.
If you have specific labels or options for boxes, feel free to provide them, and I can guide you on how to correctly match them with parts of the reaction!
