The energy released in fusion reaction,
Explanation of Solution
To calculate the no of neutrons, release from the above equation. The mass should be equal to the left side and right side of the equation for balancing the equation. So, equate the left side and right side of the masses. We get,

- A nuclear physicist finds 1.0of 236Uin a piece of uranium ore (T1/2=2.348107y) . (a) Use die decay law to determine how much 236Uwould had to have been on Earth when it formed 4.543109yago for 1.0gto be left today, (b) What is unreasonable about this result? (c) How is this unreasonable result resolved?arrow_forwardAnother set of reactions that result in the fusing of hydrogen into helium in the Sun and especially in hotter stars is called the carbon cycle. It is 12C+1H13N+, 13N13C+e++ve, 13C+1H14N+, 14N+1H15O+, 15O15N+e++ve, 15N+1H12C+4He. Write down the overall effect at the carbon cycle (as was done for the protonproton cycle in 2e+41H+4He+2ve+6. Note the number of protons (lH) required and assume that the positrons (e+) annihilate electrons to form more (rays.arrow_forward(a) How much energy would be released if the proton did decay 1uria the conjectured reaction (b) Given that the decays to two (s and that the will find an electron to annihilate, what total energy is ultimately produced in proton decay? (c) Why is this energy greater than the proton's total mass (converted to energy)?arrow_forward
- Two fusion reactions mentioned in the text are n+3He4He+and n+1H2H+. Both reactions release energy, but the second also creates more fuel. Con film that the energies produced in the reactions are 20.58 and 2.22 MeV, respectively. Comment on which product nuclide is most tightly bound, 4He or 2H.arrow_forwardUnreasonable Results A frazzled theoretical physicist reckons that all conservation laws are obeyed in the decay of a proton into a neutron, positron, and neutrino (as in (+ decay of a nucleus) and sends a paper to a journal to announce the reaction as a possible end of the universe due to the spontaneous decay of protons. (a) What energy is released in this decay? (b) What is unreasonable about this result? (c) What assumption is responsible?arrow_forwardIt is estimated that weapons tests in the atmosphere have deposited approximately 9 MCi of 90Sr on the surface of the earth. Find the mass of this amount of 90Sr.arrow_forward
- Construct Your Own Problem Consider the decay of radioactive substances in the Earth's interior. The energy emitted is converted to thermal energy that reaches the earth's surface and is radiated away into cold dark space. Construct a problem in which you estimate the activity in a cubic meter of earth rock? And then calculate the power generated. Calculate how much power must cross each square meter of the Earth’s surface if the power is dissipated at the same rate as it is generated. Among the things to consider are the activity per cubic meter, the energy per decay, and the size of the Earth.arrow_forwardTwo fusion reactions mentioned in the text are n+3H4He+ and n+1H2H+. But reactions release energy, but the second also creates more fuel. Confirm that the energies produced in the reactions are 20.53 and 2.22 MeV, respectively.

(a) (b) Figure 32.35 (a) This xray fluorescence machine is one of the thousands used in shoe stores to produce images offset as a check on the fit of shoes. They are unshielded and remain on as long as the test are in them, producing doses much greater titan medical images. Children were fascinated with them. These machines were used in shoe stores until laws preventing such unwarranted radiation exposure were enacted in the 1950s (credit: Andrew Kuchling ) (b) New that we know the effects of exposure to radioactive material, eatery is a priority.
