• A. N2
• B. CO2
• C. O2
• D. H2

Answer: (C)

Verified step by step guidance

1. Understand that the problem asks about the gas produced when hydrogen peroxide (H\_2O\_2) decomposes.
2. Recall the decomposition reaction of hydrogen peroxide, which breaks down into water (H\_2O) and oxygen gas (O\_2).
3. Write the balanced chemical equation for the decomposition: 2H\_2O\_2 (aq) \(\rightarrow\) 2H\_2O (l) + O\_2 (g).
4. Identify the gas produced in this reaction by looking at the products; the gas is oxygen (O\_2).
5. Confirm that the other options (N\_2, CO\_2, H\_2) are not produced in this reaction based on the chemical equation.
