AI Thread Summary
To calculate the energy release from the complete fusion of one mole of deuterium, one must consider the reaction where two deuterium nuclei fuse to form helium and energy. The mass of deuterium is approximately 2.0141018 amu, while helium has a mass of about 4.0026033 amu. The energy released can be derived from the mass difference using Einstein's equation, E=mc², where the mass change can be determined by applying Avogadro's constant to convert moles to atoms. The discussion emphasizes the importance of understanding mass change in fusion reactions to calculate energy output effectively. This process is crucial for comprehending nuclear fusion and its potential energy applications.

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 _{1}^{2}D contains ~6.023\cdot 10^{23} 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.
 
m_{_{1}^{2}D}\approx 2.0141018 \ \mbox{amu}

m_{_{2}^{4}He}\approx 4.0026033 \ \mbox{amu}

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

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
