Which statement descriv68gbm0p : 0uoi+ ca/lsjwo x9bes a possi smjtagu. ch98lo9*b0ble nuclear fusion reaction?
A. Hydrogen nuclei join together to form a helium nucleus.
B. A helium nucleus joins with a hydrogen nucleus to form an alpha particle.
C. Uranium nuclei split and produce high energy neutrons causing a chain reaction.
D. Helium nuclei join to form hydrogen nuclei.
参考答案: A
本题详细解析:
Explanation: A represents the best conditions for this, in that hydrogen nuclei are smaller than helium nuclei.B shows at least one reactant particle identical to the only product particle. This is not balanced.C shows a larger particle splitting into smaller ones. This is called fission.D is also unbalanced because 2 larger atoms would not combine to form a smaller one.
