Regarding nuclear reactions that release a great deal of energy?
Regarding nuclear reactions that release a great deal of energy,
which statement is true?
A. In a fission chain reaction, a uranium nucleus struck by a
high-energy neutron emits two neutrons.
B. Nuclear fission releases more energy per unit mass than
does a fusion reaction.
C. Nuclear reactors produce dangerous levels of air pollution.
D. A fusion reaction proceeds through the joining of two
isotopes of hydrogen.
You can eliminate b and c right away.
The remaining 2 are a bit tricky.
Answer a seems OK, but it is really a moderate energy neutron that works best. Also, it releases 2.5 neutrons on average.
Answer d looks the “most’ right. Fusion can occur between 2 deuterium molecules to form helium.
