Question

What is the energy released in this nuclear reaction   53131I ?   54131Xe +   -10e? (The atomic mass of 131I is 130.906124 u and that of 131Xe is 130.905082 u)

What is the energy released in this nuclear reaction     49Be +   11H ?   36Li +   24He? (The atomic mass of 9Be is 9.012182 u, and that of 6Li is 6.015121 u)

Can anyone tell me what I did wrong? I took the change in mass * 931.5 :( and got the wrong answers.

I24 8. What is the energy released in this nuclear reaction 1 13 Xe + e? (The atomic mass of 1311 is 130.906124 u and that of 131 Xe is 130.905082 u) Your submitted answer is: 0.4596208 MeV X Your submitted answer is: 0.4596208 MeV 9. What is the energy released in this nuclear reaction Be + SLi + tHe? (The atomic mass of 9Be is 9.012182 u, and that of 6Li is 6.015121 u) Your submitted answer is: 2.2346685 MeV

Explanation / Answer

8) Q = (mI - mXe)c^2

Q =(130.906124 u - 130.905082 u)c^2

Q = (130.906124 - 130.905082 )*931.5 MeV

Q = 0.9706 MeV

9) Q = (mBe +mH - mLi - mHe)*c2^

Q = ( 9.012182 u +1.007825 u - 6.015121 u- 4.002603 u)*c^2

Q = ( 9.012182 +1.007825 - 6.015121 - 4.002603 )*931.5 MeV

Q = 2.13 MeV
