pathways. for the ission of u-235 induced by a neutron, write a nuclear equation to form: a. bromine-87, lanthanum-146, and more neutrons. b. a nucleus with 56 protons, a second with a total of 94 neutrons and protons, and 2 additional neutrons.

a)

b)

Explanation:

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

a) The given reaction is

Now,  as the mass on both reactant and product side must be equal:

Thus three neutrons are produced and nuclear equation will be:

b) For the another fission reaction:

To calculate A:

Total mass on reactant side = total mass on product side

235 + 1 = A + 94 + 2

A = 140

To calculate Z:

Total atomic number on reactant side = total atomic number on product side

92 + 0 = 56 + Z + 0

Z = 36

As Krypton has atomic number of 36,Thus the nuclear equation will be :

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
