Answers below are taken from the article’s stored facts, so they match what the student read.

1. Who discovered Hydrogen peroxide?1818
2. What is the chemical formula?H2O2
3. What is the discoverer?Louis Jacques Thénard
4. What is hydrogen peroxide and why does it bubble?Hydrogen peroxide is a clear liquid that has a weak bond between two oxygen atoms. When that bond breaks, it turns into water and oxygen gas, which makes bubbles.
5. How does hydrogen peroxide help clean cuts?It releases oxygen that kills germs and breaks down dirt. The bubbles help lift the germs away from the wound.

Reactive Oxygen Species (ROS): Chemically reactive molecules containing oxygen, often involved in cellular signaling and oxidative stress.
Hydrogen Bonding: An attractive force between a hydrogen atom in one molecule and an atom in another molecule.
Oxidation: A chemical reaction involving the loss of electrons or an increase in oxidation state, often involving oxygen.
