Homework Help Overview

The discussion revolves around calculating the energy release from the complete fission of 0.001 kg of Uranium-235, a topic within nuclear physics. Participants are exploring the theoretical aspects of nuclear reactions and energy calculations.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants are attempting to apply the mass-energy equivalence principle (E=mc²) and are discussing the necessary calculations, including the number of atoms and energy per fission event. Questions about the daughter products of the fission reaction and the specifics of the energy calculation are also raised.

Discussion Status

The discussion is active, with participants providing guidance on how to approach the problem, such as determining the number of U-235 atoms and using Avogadro's number. There is a mix of interpretations and methods being explored, but no consensus has been reached on the final calculation.

Contextual Notes

Participants are working within the constraints of homework guidelines that discourage direct solutions, prompting a focus on understanding the underlying principles and calculations involved in nuclear fission.

suppose that 0.001kg of uranium 235 (92 proton number) could be persuded to fission completely

show that the energy release would be 8x10^10 J

thanks

p.s if one could explain how they did it that would be great too thanks

We don't do your homework, we help you do your homework. Do you know the daughter products of the reaction?
 
first part is

nucleaon number/mass number = 92+0=X+54+0 =>38
atomic number/proton number = 235+1=98+X+3 =>136

i can prove the energy release using e=mc^2 and 1.66x10^-27

but its just the last part i can't do which is

suppose that 0.001kg of uranium 235 could be persuded to fission completely

show that the energy release would be 8x10^10 J

heres the question anyway

Determine the number of U-235 atoms in 0.001 kg (think Avogadro's number), then muliply the energy released per fission, and that will give the energy produced by fissioning all the atoms in 0.001 kg.
