For the fusion reaction shown below, find the amount of energy (Q) released. (Enter your answer in MeV.) H+ C - N +Y MeV

What is the mass of 60Co in a cancer therapy transillumination unit containing 5.00 kCi of 60Co?

(a) Write the complete reaction equation for electron capture by 7Be. (b) Calculate the energy released.

(a) Calculate the energy released in the neutron- induced fission n+238U96Sr+140Xe+3n , given m(96Sr)=95.921750uand m(140Xe)=139.92164 . This result is about 6 MeV greater than the result for spontaneous fission. Why? Confirm that the total number of nucleons and total charge are conserved in this reaction.

Check Your Understanding Which has a larger energy yield per fission reaction, a large or small sample of pure 235U?

(a) Write the complete decay equation for 90Sr, a major waste product of nuclear reactors. (b) Find the energy released in the decay.

(a) Calculate the number of grams of deuterium in an 80.000L swimming pool, given deuterium is 0.0150% of natural hydrogen. (b) Find the energy released in joules if this deuterium is fused via the reaction 2H+2H3He+n. (c) Could the neutrons be used to create more energy? (d) Discuss the amount of this type of energy in a swimming pool as compared to that in, say, a gallon of gasoline, also taking into consideration that water is far more abundant.

Give reasons justifying the contention made in the text that energy from me fusion reaction 2H+2H4He+ is relatively difficult to capture and utilize.

How many kilograms of water are needed to obtain the 198.8 mol of deuterium, assuming that deuterium is 0.01500% (by number) of natural hydrogen?

Data from the appendices and the periodic table may be needed for these problems. 44. An old camp?re is uncovered during an archaeological dig. Its charcoal is found to contain less than 1/1000 the normal amount of 14C. Estimate the minimum age at the charcoal, noting that 210 = 1024.
