Answer : In the first reaction, 'A' is the atomic mass of barium = 143

In the second reaction, 'B' is the atomic mass of barium = 145 and 'C' is the atomic number of barium = 56

Explanation :

Nuclear fusion : It is a process which involves the conversion of two small nuclei to form a heavy nuclei along with release of energy.

Nuclear fission : It is a process which involves the conversion of a heavier nuclei into two or more small and stable nuclei along with the release of energy.

The complete nuclear fission reaction are,

(1)

In this reaction, 'A' is the atomic mass of barium = 143

(2)

In this reaction, 'B' is the atomic mass of barium = 145 and 'C' is the atomic number of barium = 56

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
