Which statement descrirjgr j;(pm c b6g*52qhbes a pod4be:2yl 3kfbssible nuclear fusion reaction?

A. Hydrogen nuclei join together to form a helium nucleus.

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.
