No. Hydrogen peroxide (H2O2) decomposes into water (H20) and Oxygen (O2). However, in the presence of certain metal ions (such as Fe2+), the Fenton reaction occurs, forming free radicals.

No, hydrogen peroxide, H202, decomposes into very safe substances. In a balanced equation, two moles of H202 decomposes into two moles of water (H20) and one mole of oxygen (02).
