Energy and chemical change grade 11

WebElementary! 2H2 + O2 = 2H2O + Energy. This “green” reaction releases massive amounts of energy along with super heated water (steam). The hydrogen-oxygen reaction generates tremendous heat, causing the water vapor to expand and exit the engine nozzles at speeds of 10,000 miles per hour! Web12.4 Chapter summary (ESBQS) When a reaction occurs, bonds in the reactants break and new bonds in the products form. These changes involve energy. When bonds break, energy is absorbed and when new bonds form, energy is released . The bond energy is …
