Homework Help Overview

The discussion revolves around calculating the energy release from the fusion of deuterium, specifically focusing on the reaction between hydrogen isotopes to form helium. Participants are exploring concepts related to nuclear fusion and energy calculations.

Discussion Character

  • Exploratory, Assumption checking, Mathematical reasoning

Approaches and Questions Raised

  • Participants are attempting to calculate the energy release for the fusion of deuterium, questioning how to determine mass changes and the relevant atomic masses. There are inquiries about the use of the Avogadro constant and how to apply it in this context.

Discussion Status

The discussion is active, with participants sharing information about atomic masses and expressing confusion regarding the calculations needed to find the mass change during fusion. Some guidance has been provided regarding the necessary atomic mass values, but no consensus or resolution has been reached.

Contextual Notes

Participants are facing challenges with the specifics of mass calculations and the implications of the Avogadro constant in their problem-solving process. There is an emphasis on understanding the mass of atoms in relation to the fusion reaction.

Calculate the energy release for the complete fusion of one mole of deuterium

H + H = He + energy

i can't do the signs for mass number etc. it quotes the Avogadro constant so that's a clue but help!

1 mole of [itex]_{1}^{2}D[/itex] contains ~[itex]6.023\cdot 10^{23}[/itex] atoms...

When fusing 2 atoms how much energy is released...?

Daniel.
 
yeah i did all that but i got bogged down in finding the mass change. remind how to find the mass of atoms when you have the atomic no. + Av. constant please.
 
[tex]m_{_{1}^{2}D}\approx 2.0141018 \ \mbox{amu}[/tex]

[tex]m_{_{2}^{4}He}\approx 4.0026033 \ \mbox{amu}[/tex]

That's all u need to know,u have the reaction's equation,already.

Daniel.
