Have you ever wondered why hydrogen peroxide is stored in dark brown containers? There's a really good reason for that. Hydrogen peroxide breaks down into water and oxygen gas. Many different things can cause this breakdown reaction, classified as a decomposition reaction, to happen. For example, when hydrogen peroxide comes into contact with enzyme in human blood, it breaks down into water and oxygen gas. That's why hydrogen peroxide bubbles if it comes into contact with blood. Exposure to light also causes this reaction to happen. In order to prevent the hydrogen peroxide from breaking down into water and oxygen gas in the bottle, sunlight has to be kept outside of the bottle. To do that, the bottle needs to be a dark color.

Consider the hydrogen peroxide decomposition reaction represented by the space-fill model shown. Parts of the reaction are labeled in boxes under the parts of the equation. Drag the correct label to each box.

GPT-4o mini · Answer

It seems like you're referring to an interactive activity where you can label parts of a chemical reaction represented by a space-fill model. Although I can't drag and drop labels myself, I can help you understand the different components of the hydrogen peroxide decomposition reaction and what kind of labels you might encounter.

The decomposition reaction of hydrogen peroxide (H₂O₂) can be represented as:

2 H₂O₂ → 2 H₂O + O₂

Here are some common labels you might need to match to parts of this reaction:

Reactant: This is the substance that is present before the reaction occurs. In this case, it would be Hydrogen Peroxide (H₂O₂).
Product: These are the substances that are formed as a result of the reaction. In this reaction, the products are Water (H₂O) and Oxygen gas (O₂).
Decomposition Reaction: This specifies the type of reaction that is occurring—breaking down a compound into simpler substances.
Catalyst (if applicable): In some contexts, an enzyme like catalase can be involved in speeding up this reaction without being consumed by it.

When labeling, make sure you apply each label correctly to the appropriate part of the space-fill model based on the function of each component in the reaction. If you have specific labels or a visual that you would like help with, feel free to describe it, and I can guide you further!
