Question 7a: On Earth in 2017, the amount of electrical energy
used was 8.03 x 1016 J. How much mass would need to be converted
directly to energy to release this much energy?
Question 7b: Imagine this conversion of mass to energy all came
from nuclear fission reactions of the element uranium. Assume the
reaction is 35% efficient: that means that the mass you calculated
above to produce the electrical energy is only 35% of the total
mass that was converted to energy. The other 65% was “waste”
energy. How much total mass was converted to all kinds of
energy?
Question 7c: The amount of mass actually converted to energy is
just a small fraction of the original uranium’s mass: just
0.0000885 of the original mass (0.00885%). Given all these
assumptions, how much total mass of uranium must be available to
create all the electrical energy used in the world, in one year?
(The total reserve of uranium-235 currently available is about
37,000 tonnes, or 3.7 x 107 kg.)

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?
Q.8: An electrical power plant operates on the basis of thermal energy generated in a pressurized water reactor. The electrical power output of the plant is 1 GW, and its efficiency is 30% (a) Find the total power generated by the reactor. (b) How much power is discharged to the environment as waste heat? (c) Calculate the rate of fission events in the reactor core (Let the energy produced per fission event be 200MeV) (d) Calculate the mass of 235U...
Il Review | Constants Periodic Table Unlike chemical reactions, for which mass is conserved, nuclear reactions result in slight changes in mass. When mass is lost, it becomes energy according to the equation Natural gas (mainly CH4) is used in many power plants to generate electrical power utilizing combustion reactions. Uranium-235 is used to generate power utilizing nuclear fission. Fusion reactions involving hydrogen-1 are under investigation as a future source of electrical power. AE=Amục where AE is the energy in...

Calculate the amount (in kilograms) of mass converted to energy by the fusion of 2.70 kg of hydrogen. kg (b) What is the ratio of mass destroyed to the original mass, Am/m? (c) How does this compare with Am/m for the fission of 2.70 kg of uranium? Fission of 1.00 kg of uranium releases 8.0 x 1013). (Am/my/Am/mu) Table 7.1 Energy of Various Objects and...
In this problem, we're going get a rough estimate the amount of uranium fuel it would take if the US recieved all its electrical power from nuclear power plants. The size of a power plant in normally given as the about of electrical power it can produce when running a full capacity. This electrical power produced can be very different than the mechanical or thermal power that was required to produce this electricity. For example, power plant might have a...
Please show all work thank you! (Assignment 25 (Chapter 19) Nuclear Fission and Fusion < 3 of 10 > Review | Constants Periodic Table - Part A Certain heavy nuclei undergo nuclear fission when struck by neutrons, breaking apart into fragment nuclel and releasing a large amount of energy. Light nuclei undergo nuclear fusion when healed to very high temperatures, forming heavier nuclei and releasing large amounts of energy. Sort these isotopes by whether they are most likely to undergo...

choose correct answer. no explanation needed QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...
