(a). The isotope 93Li undergoes beta decay. Write the reaction equation and determine the identity of the daughter nucleus. (2.0 points) (b). The following is a possible fission reaction. Balance the decay equations and determine the identity of the missing nucleus. 10n + 23592 U → 9539Y + ? + 210n (1.5 points) (c). Uranium-238 undergoes alpha decay as follows: 23892 U→ 42He + 23490 Th Mass 23892 U = 238.050786 u, Mass 42 He = 4.002603 u and mass 223490 Th =234.043583 u Calculate the binding energy (to four significant figures) for this nuclear reaction. (2.5 points). u = 1.66 x 10-27 kg c= 3.0 x 10 8 m/s eV = 1.6 x 10 -19 J
