Another series of nuclear reactions that can produce energy in the interior of stars is the carbon cycle first proposed by Hans Bethe in 1939, leading to his Nobel Prize in Physics in 1967. This cycle is most efficient when the central temperature in a star is above 1.6 x 10^7 K. Because the temperature at the center of the Sun is only 1.5 x 10^7 K, the following cycle produces less than 10% of the Sun’s energy. (a) A high-energy proton is absorbed by 12C. Another nucleus, A, is produced in the reaction, along with a gamma ray. Identify nucleus A. (b) Nucleus A decays through positron emission to form nucleus B. Identify nucleus B. (c) Nucleus B absorbs a proton to produce nucleus C and a gamma ray. Identify nucleus C. (d) Nucleus C absorbs a proton to produce nucleus D and a gamma ray. Identify nucleus D. (e) Nucleus D decays through positron emission to produce nucleus E. Identify nucleus E. (f) Nucleus E absorbs a proton to produce nucleus F plus an alpha particle. Identify nucleus…

10. A nuclear reactor is 35% efficient and has a power output of 350 MW. If we consider all the fission reactions to give out the same energy, 2.78 x 1011 J how many moles of uranium-235 is needed each second by the power station? AA 5.975 x 105 B 5.935 x 105 C 5.835 x 105 D 5.739 x 105

Scientists have continuously been searching for ways to create a system for energy production through fusion reactions but have been unsuccessful. Which of the following explains why it is still not a practical source of power? O Fusion can create a huge amount of energy with very little fuel. O Fusion radioactive byproducts have a shorter half-life than fission byproducts. O Fusion requires a large amount of energy to force atoms to initially fuse together. O Fusion reactions have virtually little to no risk of nuclear accidents.
