Which of the following statements about hydrogen peroxide (H2O2) is accurate?

1. The reaction H2O2 + [O] results in the formation of H2O and O2 gas.
2. Hydrogen peroxide reacts with [O] to yield water and oxygen gas.
3. The volume strength of hydrogen peroxide is calculated as 5.6 × Normality, which equals 8.4 L for a normality of 1.5.
4. The bond angle of the O–O–H structure in hydrogen peroxide is 97°.

Correct answer: The bond angle of the O–O–H structure in hydrogen peroxide is 97°.

Solution
