WebWater contains hydrogen and oxygen and electrical energy is causing water to split into these elements. The formula of water is H 2 O so you expect twice the volume of hydrogen to form as oxygen: 2H 2 O (l) → 2H 2 (g) + O 2 (g) The explosion is caused by the energy released when the gases recombine to form water. WebWhen molecular hydrogen (H 2) and oxygen (O 2) are combined and allowed to react, energy is released and the molecules of hydrogen and oxygen can combine to form either water or hydrogen peroxide.However, hydrogen does not react with oxygen at room temperature, a source of energy is required to break the covalent bonds that hold the H 2 … hardman trust awards

WebThe reaction is strongly inhibited by increasing the partial pressure of oxygen; conversely, it is possible to produce explosion by reducing the partial pressure of oxygen below a … Oxyhydrogen will combust when brought to its autoignition temperature. For the stoichiometric mixture, 2:1 hydrogen:oxygen, at normal atmospheric pressure, autoignition occurs at about 570 °C (1065 °F). The minimum energy required to ignite such a mixture, at lower temperatures, with a spark is about 20 microjoules. At standard temperature and pressure, oxyhydrogen can burn when it is between about 4% and 95% hydrogen by volume.
