A Uranium-235 atom undergoes fission in the following net reaction (induced fission involves an intermediate step as U-236 which we will ignore): U-235 --> X + Y + 2n U-235 is the 'parent', X and Y are 'daughters' (= fission products), n = free neutron. 1 u = atomic mass unit = 1.66 x 10-27 kg mn = mass of a neutron = 1.008665 u mp = mass of a proton = 1.007825 u 1 eV = 1.602 x 10-19...
A typical nuclear fission reaction involving uranium-235 produces 9.2 × 10 7 kJ/g of uranium. How much energy would be released if 1 mol of uranium-235 undergoes fission? A. 5.5 × 1021 kJ B. 3.9 × 105 kJ C. 9.2 × 107 kJ D. 2.2 × 1010 kJ
4. The energy released by the fission of one atom of uranium-235 is 3.2 x 10 R J. The energy released by the atomic bomb dropped at Hiroshima was estimated to be the equivalent of 18 140 t of dynamite or 8.0 × 1013 J (a) How many atoms of uranium-235 underwent fission? (b) What mass of uranium-235 was converted into energy?
Nuclear power plants convert the energy released in fission reactions to electric energy. Consider one such power plant that generates 1.00 GW of electric power. The fission of each uranium-235 nucleus releases 200 MeV of energy. The power released by the fission reactions is converted to electric power with a 41.0% efficiency. How much uranium-235 per day, by mass in kg, undergoes fission at this power plant?
In a nuclear reactor, each atom of uranium (of atomic mass 235 u) releases about 200 MeV when it fissions. What is the change in mass when 1.30 kg of uranium-235 is fissioned? Answer in Kg
Consider a fission reaction where a Uranium-235 nucleus absorbs a neutron and then splits to Strontium, Xenon, and some neutrons. If the strontium nucleus has a mass number of 89 and the Xenon nucleus has a mass number of 144, how much energy is released in a single reaction? Use the attached table for the atomic masses of the nuclei. Give your answer in MeV and with 4 significant figures. (Hint: Balance the reaction first). Isotope Masses for Fission A...
Consider a fission reaction where a Uranium-235 nucleus absorbs a neutron and then splits to Strontium, Xenon, and some neutrons. If the strontium nucleus has a mass number of 93 and the Xenon nucleus has a mass number of 140, how much energy is released in a single reaction? Use the attached table for the atomic masses of the nuclei. Give your answer in MeV and with 4 significant figures. Neutron 0 1 1.008665 Uranium 92 235 235.043923 Strontium 38...
3. 10 points SerCP10 30 WU.003 A typical uranium-235 fission event releases 209 MeV of energy. (a) Determine the energy released per event in joules (b) Determine the change in mass during the event. kg
The average energy released by the fission of a single atom of uranium-235 is approximately 205 MeV How much total energy would be released by the complete fission of 3.55 kg of 3sU? Express your answer in units of joules. 2.98 x1015 A typical small town might use about 25.5 MW of power, on average. How long, in days, would it take this town to use the amount of energy produced by the complete fission of 3.55 kg of 2U?...
Burning 20 tons of coal provides about 5. 1011 J, which is approximately the annual energy requirement of an average person in the United States. If this amount of energy was provided by the electricity generated by the fission of uranium-235 in a nuclear reactor, instead, what mass of natural uranium would be required? About 0.7% of natural uranium is uranium-235 (almost all the rest is uranium-238, which does not fission like U-235 does). Assume that the fission of each...
