6. Smoke detectors contain small amounts of americium-241. Am-241 decays by emitting alpha particles and has a decay constant of 1.51x103/y. If a smoke detector gives off ten disintegrations per second how many grams of Am-241 are present in the detector? 7. Calculate the mass defect (Am) and the binding energy of Berylium-9. ANSWER 1/6..07 53 E 8. Considerthe fission reaction in which U-235 is bombarded by neutrons. The products of the bombardment are Rb-89. Ce-144, beta particles and more neutrons. The atomic mass of Rb-89 is 88.912278 and Ce- 144 is 143.91365. a. Write the balanced nuclear equation for the bombardment. 85u+n ce+ 3 ANSWER utogn Rb +144Cet3e + &4 5. Oalculate AE when one gram of U-235 undergoes fission. ANSWER c. The detonation of TNT, an explosive, evolves 2.76 kJ/g/ How many kilograms of TNT are required to produce the same amount of energy as one milligram of U-235? ANSWER
