U-235 undergoes many different fission reactions. for one such reaction, when u-235 is struck with a neutron, ce-144 and sr-90 are produced along with some neutrons and electrons. how many neutrons and -particles are produced in this fission reaction?

Explanation:

A nuclear fission reaction is defined as the reaction in which a heavy nucleus splits into small nuclei along with release of energy.

The given reaction is

Now, we balance the mass on both reactant and product side as follows.

         235 + 1 =

           236 = 234 + x

            x = 236 -234

               = 2

So, now we balance the charge on both reactant and product side as follows.

              92 + 0 =

                92 = 96 - y

                  y = 4

Thus, we can conclude that there are 2 neutrons and 4 beta-particles are produced in the given reaction.

Therefore, reaction equation will be as follows.

the answer is option a.
