One possible outcome in the fission of a uranium nucleus is the reaction $\frac{233}{92} \mathrm{U}+_{0}^{1} \mathrm{n} \rightarrow_{42}^{95} \mathrm{Mo}+_{57}^{139} \mathrm{La}+2_{0}^{1} \mathrm{n}+?$ (a) What is missing in this reaction? (b) How much energy is released? (Atomic masses: $U=235.043922 \mathrm{u}$ $\mathrm{Mo}=94.905841 \mathrm{u} ; \mathrm{La}=138.906349 \mathrm{u} .)$

This question we want to find What is the energy being released for you, Shorty? Reaction for this particular nickel Fisher reaction involving the neutron bomb. Bartman off! Ah, Uranium 235 We're gonna find SD Cuba, which is the energy release. And they're so close to d changing the mess. What? Backed by C squared? Not about Getty changing mess be. You said she take the initial messes, Toto. Initial messes minus e final messes off the products to get Wasti changing, Miss. And since we are given the Tommy messes so the ultimate master sexual include the electron messes as well for the zirconium and inter Alia Ah, new crisis. But we shouldn't need the electrons, right? And the total number of electrons on the left on the right actually is over. Here is 40 pastors to tell B 92 and you will be cancelled out by 18. 92 electrons on the atomic Man Softy uranium. Right. So what we have to do is to use the atomic mess for uranium s well in order to cancel the total of electrons. Right? So remember that the change in the message sti in the show, Mrs Softee Records. Jeez. Uranium 235 plus de mer. Softy neutron. We subject that we've d mess off zirconium mess off to really, um, and the mass off neutrons, right? Three times to mess with you join and every Multiply this by C Square and see if we were gonna use it. Actually, one point for, like, four MVV for you since you're working reef atomic mass units? No. All of these are told me, Mrs. So for the atomic myself, you know, 235 Nice to verify. Why's your for tree? I took tree you the mass softy. Neutron. Neutron is one point. Use your 8665 you 40 Cicconi. Um, they are given e question. Right? It is 97 point night. What tools you really you to really? It is one tree full point. Nice. Your insulin. You all right? So mess often your choice to see So final answer should get 1 92 And you feel

In this question, we want to calculate the uh energy released in the vision reaction. So this is a fusion reaction. Okay, you 235 That's one neutron giving uh one for one cm plus rubidium 93. That's two neutrons king. So to calculate the energy release, he so too is delta M C square mm. So that I M is the mass difference or mass effect. Can't be done. Mass of uranium has the mass of neutron minus the mass of CSC m minus the mass of rubidium minus two times the mass of neutron time C square. So I'm going to put in the numbers and then a neutron. The net is one negative one. Right? So I'm going to bring the numbers 35 0.432 minus 140 0.91 96. 3 minus H two. Yeah 0.92157 minus 1.867 Okay, the atomic mass unit. I'm going to put it out as you see square and then you get 0.919505 And when you see square is 91.5 and maybe. Mhm. The answer is all right. Anyone maybe. Okay, so this is the answer for this question and that's all.

Hello. And in this question here we want to find out the energy that is released when one neutron, a slow moving neutron is absorbed by uranium 235. And the uranium fishing's into Z serve zirconium atom plus uh uh that is uh sorry that's a teller Reum atom plus three neutrons. Okay. And to find the energy released in this equation here, we're going to use conservation of energy and well the initial energy that's just going to be the rest mass energy of the neutron plus the rest mass energy of the uranium. And it's a slow moving neutron. So we can assume there's no kinetic energy. Okay. Or that the kinetic energy is small in comparison to the S maths energies. Now the final energy that is equal to the rest mass of Zaire, zirconium. Okay. Plus the asthma's energy of terrorism Plus three times the rest mass energy of the neutrons plus the energy that is released to the environment. So we can rearrange for the energy released to the environment. And this is equal to the mass of uranium minus twice the mass of the new year of the neutrons, minus the mass of the zirconium and minus the mass of the tele re um Okay. And that's all multiplied by C squared. Now we need to find out what these masses are and we can fill in, we can look the masses up and the mass of the uranium 2 3 five is equal to 235.4323. You the mass of the neutron is equal to 1.866. You the mass of the Zeer Zirconium is equal to 97.91 to you. And the mass of the tele reum is equal to 134.9087. Okay. And you can just look these masses up in dependencies in the back of the book, filling these masses in. We get to the energy release to the environment is equal to 0.205813 U times c squared you is the atomic unit of mass and has a value of 1.67 times 10 to the power of minus 27 kg. C. is the speed of light. That's a value of three times center. The eight meters per second. Okay, so we can some of the values of you and see and get that. The total energy released is equal to 3.93 threes uh three times 10 to the power of minus 12 jewels. Okay. And you can convert this into electron volts by dividing, sorry, that should be minus 11. And you can convert into electron volts by dividing by 1.6 times 10 to the power of minus 19. So this means the energy released is equal to 193 mega electron volts. Okay, so that there is the solution to this question. Thank you for listening.

To find the energy that's being released by this nuclear fission reaction. Well, first you find a mess defect, and the rest effect is to fine sticking the mess off the products minus T mass. Softy reckons, You know what this tells us is the amount off mess that WAAS actually covered it into energy. By this particular officially reaction and two related to energy, we use Einstein's equation e equals toe M C Square. So now, to find the mass defect first were given the mess off the products for Sacconi a man trillion. So we can't be right until so far the economy is 97. I want to 75 you and for two Radio country four point no. 16450 And we have tree you trance that are involved. The mayor softy neutrons s Well, you can search for the mess off the neutrons on thing. Now the subject, the masses, Swifty, mess off the reactions. So that is one your trunk with team s off uranium to tree five and this year also have to look it up. And yet he messed effect to be to appoint one night. So for one you now we can Finally. The kits. What? ISTEA Total energy has been released. She goes to the message effect multiplied by C Square and C script. We are using deform 91.494 m e report you for convenience because we are dealing with atomic units. So the final on so that we should get ISS 100 e g 0.9 everything.
