Two other possible ways by which .^(235)...

Two other possible ways by which `.^(235)U` can undergo fission when bombarded with a neutron are (1) by the release of `.^(140)Xe` and `.^(94)Sr` as fission fragments and (2) by the release of `.^(132)Sn` and `.^(101)Mo` as fission fragments. In each case, neutrons are also released. Find the number of neutrons released in each of these events.

Verified by Experts

By balancing mass numbers and atomic numbers, we find that these reaction can be written as
`{:(._(0)^(1) n +._(92)^(235) U rarr. _(54)^(140)Xe +._(38)^(94) Sr + 2. _(0)^(1) n),(._(0)^(1) n +._(92)^(235) U rarr ._(50)^(132)Sn +._(42)^(101) Mo + 3._(0)^(1) n):}`
Thus, two neutrons are released in the first event and three in the second.
