Question

Given the nuclear equation:

235     1        142         91        1
    U +   n -->       Ba +     Kr + 3  n + energy
 92      0         56         36         0

State the type of nuclear reaction represented by the equation.

This one sounds so hard PLEASE HELP ANYONE! :(

jfraser · Answer

You've got 1 large particle being split by a subatomic particle (the neutron) into larger fragments and more neutrons. This isn't one of the decay types, and it's not fusion.

If those neutrons hit more U-235 atoms, the reaction will continue and get larger and larger, forming a chain reaction.

Wait so its fission right?

jfraser · Answer

yes

anonymous · Answer

The sum of the masses of the products is slightly less than the sum of the masses of the reactants. Explain this loss of mass.

I don't get how it lost the mass?

anonymous · Answer

The loss in mass is the mass defect.
The loss in mass is the energy released. E=mc^2.
If mass is not lost energy can't be released.
