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 help explain away a common misconception, namely what is in the bubbles found in boiling water. Since boiling does not break the bonds in a water molecule, the bubbles are composed of water vapor. In contrast, within liquid water, there is a chemical reaction that is going on â the disassociation of water into âOH and H+, which we will discuss in more detail shortly. However a naked proton (H+ that is a proton as a discrete separate species) does not exist in water, this reaction is more accurately written as:
