A nuclear reaction is represented by the following equation: U 92 235 + n 0 1 → B 56 139 a + K 36 94 r + x c + E What type of bomb is based on similar type of reactions?

Atom bomb is based on the nuclear fission reaction. Nuclear fission is a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into two or more smaller, lighter nuclei.

How much is 4 . 5 × 10 14 J in MeV ? (Speed of light, c = 3 × 10 8 m s )

1 . 602 × 10 - 13 J = 1 MeV ∴ 1 J = 1 1 . 602 × 10 - 13 MeV ∴ 4 . 5 × 10 14 J = 4 . 5 × 10 14 × 1 1 . 602 × 10 - 13 MeV = 2 . 8 × 10 27 MeV .
