Nuclear Reactions

Calculate the energy in $\mathrm{Mev}$ released in the nuclear reaction ${}_{77}{}^{174}\mathrm{Ir}\to {}_{75}{}^{170}\mathrm{Re}+{}_2{}^4\mathrm{He}$. Atomic masses $:\mathrm{Ir}=173.97 \mathrm{u},$ $\mathrm{Re}=169.96 \mathrm{u}$ and $\mathrm{He}=4.0026 \mathrm{u}$ 

Write the fusion reactions occurring in the Sun and stars.

Write one point that differentiates nuclear reactions from chemical reactions.

Balance the nuclear reaction,

${}_{54}{}^{118}\mathrm{Xe} \to ? + {\mathrm{I}}_{53}^{118}$

Energy produced in nuclear fusion is much larger than that produced in nuclear fission. Why is it difficult to use fusion to produce energy?

Explain in brief, nuclear fission.

The process by which nuclei having low masses are united to form nuclei with large masses is 

The missing particle from the nuclear reaction is
${}_{13}{}^{27}\mathrm{Al}+{}_2{}^4\mathrm{He}⟶? + {}_0{}^1\mathrm{n}$

It has been found that the Sun's mass loss is $4.34\times {10}^9 \mathrm{kg}$ per second. How much energy per second would be radiated into space by the Sun?
