Hello, and in this question here, we'll be looking at the energy released in this fission reaction.
00:08
So we have a neutron, and this neutron interacts with the nucleus of the uranium 235 to produce a barym 141, a crontium 92 and three neutrons.
00:20
In this reaction, there'll be energy released, and we want to find this energy that is released.
00:26
So this energy, we're going to represent by capital e, and this is equal.
00:31
To the difference in mass from the initial products to the final products.
00:38
So delta m is the difference of mass of the final state minus the initial state minus the final state.
00:46
So there's delta m is equal to the mass of the uranium atom nucleus or atom minus the mass plus the mass of the neutron minus the mass of the final slate products.
01:00
So this is the mass of the barium, minus the mass of the crontium, minus the mass of three neutrons.
01:09
So that's going to be three times the mass of a neutron.
01:12
And if we multiply this by c squared, we will be able to determine the energy released.
01:19
So looking at the appendices in the back of the book, the mass of the uranium 235, is equal to 235 .0443599u.
01:38
The mass of the neutron is equal to 1 .008 -6649u.
01:48
The mass of the barium atom is equal to 140 .914440 .4 .4 .4...
