6. The other isotope that undergoes a chain reaction like U-235 is Pu-239. One of the two bombs used at the end of World War II was a plutonium bomb.) One reaction for Pu-239 is 239Pu + n9Y+ 137Cs +4n The masses of the isotopes are 239Pu: 239.052 n: 1.009 99Y: 98.925 137Cs: 136.907 amu a) What fraction (in decimal form of the original mass is lost in the reaction? b) For every kg of Pu-239 that reacts, how many kg of mass is lost? c) For every kg of Pu-239 that reacts, how many J of energy is generated? ans c) 7.2 x 10 d) Assuming all the Pu-239 in a bomb reacts, how many kg of Pu-239 is needed to release an energy of 20 kilotons TNT? a e) If only 5% of the Pu-239 in a bomb reacts, how many kg of Pu-239 is needed to release an energy of 20 kilotons TNT?
