HO H 'H 2. (Fusion) A large amount of evidence exists that the sun's energy is produced by nuclear fusion. A model of this process (the proton-proton chain) is shown in the figure at the right. Key to this process is the fusion of Helium nuclei: 'H 'H H H 3 He + 3He = "He + 2 protons > He не d) Sketch the BEN curve below and locate the above nuclei on the curve. e) Determine the energy released in this reaction. f) Model this reaction with an energy-bar diagram. (A blank diagram is given on the following page.) H Y V *Не
