When hydrogen peroxide bubbles, it is undergoing a chemical change. Which statement best describes what is happening? The atoms in hydrogen peroxide are breaking apart and forming new types of molecules. Four students are analyzing four different substances and recording their findings in this table.
This is what happens when blood comes into contact with 30% hydrogen peroxide. What you're seeing is the chemical reaction between the enzyme catalase (which is found in our blood cells) and the hydrogen peroxide itself. When they come into contract with each other, the hydrogen peroxide turns into oxygen and water. The bubbles you see are pure oxygen being released as a result of the combination.
