How to Calculate Energy Released in Fission Reaction

In summary, using the given reaction, the amount of energy can be determined by calculating the difference in mass between the initial and final states and using the equation E = delta m(c^2). However, the given attempt at a solution appears to be incorrect and further clarification is needed on how to incorporate the middle product into the equation.

Homework Statement



1_0_n + 235_92_U 140_54_Xe + 94_38_Sr + 2 1_0_n
Using the above reaction, determine the amount of energy.


Homework Equations



mi = 235.043925u + 1.008665u + 236.05259u
mf = 140.914406u + 93.915356U + 2(1.008665u) = 236.847092Uu
delta m = 0.794502
E = deltam(c^2) = (0.794505u)(931.5MeV/c^2/u)c^2 = 740.078613

The Attempt at a Solution



See above in part . My answer is incorrect. I double checked my work, and I got the same answer. Can anybody figure out what I'm doing wrong? Thanks.

Compare:

mi = 235.043925u + 1.008665u

m (U-236) = 236.05259u

mf = 140.914406u + 93.915356U + 2(1.008665u)


235U + n -> 236U* -> FP + 2n

Okay, how do I incorporate the middle product into my equation? The book wasn't too good with explaining that part.
 

1. What is a fission reaction problem?

A fission reaction problem is a scientific issue that arises when attempting to control and harness the energy produced by nuclear fission. This involves balancing the rate of fission reactions and the amount of energy released to prevent a runaway chain reaction.

2. How does a fission reaction occur?

A fission reaction occurs when a heavy, unstable nucleus of an atom, such as uranium or plutonium, splits into two or more smaller nuclei. This process releases a large amount of energy in the form of heat and radiation.

3. What are the potential dangers of a fission reaction problem?

If a fission reaction is not properly controlled, it can lead to a nuclear meltdown, which can release harmful radiation into the environment. This can have serious health and environmental consequences, including cancer and genetic mutations.

4. How do scientists work to prevent fission reaction problems?

Scientists use various methods to prevent fission reaction problems, such as controlling the fuel used in nuclear reactors, designing safety systems, and monitoring the reactor's temperature and pressure. Additionally, strict regulations and safety protocols are in place to prevent accidents.

5. Can fission reactions be used for peaceful purposes?

Yes, fission reactions can be used for peaceful purposes, such as generating electricity in nuclear power plants. However, it is important to carefully manage and monitor these reactions to prevent any potential problems or disasters.
