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.
Since a cut or scrape contains both blood and damaged cells, there is lots of catalase floating around. When the catalase comes in contact with hydrogen peroxide, it turns the hydrogen peroxide (H2O2) into water (H2O) and oxygen gas (O2). Catalase does this extremely efficiently -- up to 200,000 reactions per second. The bubbles you see in the foam are pure oxygen bubbles being created by the catalase.
