Which gas is produced during the decomposition reaction of hydrogen peroxide (H2O2)?
A
N2
B
CO2
C
O2
D
H2
Verified step by step guidance1
Understand that the problem asks about the gas produced when hydrogen peroxide (H\_2O\_2) decomposes.
Recall the decomposition reaction of hydrogen peroxide, which breaks down into water (H\_2O) and oxygen gas (O\_2).
Write the balanced chemical equation for the decomposition: 2H\_2O\_2 (aq) \rightarrow 2H\_2O (l) + O\_2 (g).
Identify the gas produced in this reaction by looking at the products; the gas is oxygen (O\_2).
Confirm that the other options (N\_2, CO\_2, H\_2) are not produced in this reaction based on the chemical equation.
