30.39. Set Up: where and If neutral atom masses from Table 30.2 are used, the electron masses cancel. Solve: The energy released is 30.40. Set Up: where and If neutral atom masses from Table 30.2 are used, the electron masses cancel. 1 mole of deuterium gas contains and hence Each reaction requires two deuterium nuclei, so 1 mole of gas produces reactions. Solve: The energy lib-erated is (b) The energy liberated by 1 mole of deuterium is 30.41. Set Up: The mass of a nucleus is Solve: (a) For 1 gallon, (b) 1 g contains (c) A mass of produces 26.7 MeV. (d) The total energy available would be so Reflect: If the mass of the sun were all proton fuel, it would contain enough fuel to last 30.42. Set Up: The reactions in the proton-proton fusion chain are Solve: Add the reaction equations as This gives The two and the two an each side of the reaction equation cancel and we are left with Note that both nucleon number and charge are conserved in the overall reaction. 30.43.
