The change that occurs indicating a release of bond energy when hydrogen gas (H₂) and oxygen gas (O₂) combine is a loud popping noise. This indicates that a chemical reaction is taking place, specifically the combustion of hydrogen in oxygen to form water (H₂O), which releases energy, often heard as a pop.
