Question : 10

Total: 49

The reaction above illustrates?

Solution:

Concept:

Two light nuclei combine to form a heavier nucleus, releasing energy.

Explanation:

The reaction is

^{2}_{1}\mathrm{D} + ^{3}_{1}\mathrm{T} \rightarrow ^{4}_{2}\mathrm{He} + ^{1}_{0}\mathrm{n} + \text{energy}

Deuterium (

\mathrm{D}

) and tritium (

\mathrm{T}

) are heavy isotopes of hydrogen.

They merge to form a helium nucleus and a neutron, which is a fusion process.

Answer:

C. nuclear fusion
