Einstein deduced that mass and energy are equivalent, and that E = mc2 where E = energy, m = mass, c = velocity of light. This of course applies to the actual amount of mass destroyed in a reaction, not to the total masses involved. Thus in a nuclear fission reaction in U-235, only a small amount of the total mass of the U-235 nucleus disappears to form energy, most of it appears in the masses of the two fission fragments, the total energy released is 200 Mev per fission which is about 3 x 10-11 Joules. In a chemical reaction energy is released but at a much smaller proportion of the masses involved. Bearing this in mind you can see that the total energy in objects around us is truly awesome! You can work out some figures, use kilograms for mass and meters/sec for c, E will then be in Joules.

Incomplete question
How much of Colorado's energy is nuclear?

What are the bad things about nuclear fission?
we use to much electric objects
Advantage and disadvantage of nuclear energy?
disad: very toxic waste that if not contained can cause a lot of damage and spread (ie chernobyl) adv: these days waste is contained in state of the art sealed containers and does not otherwise harm anyone. also a small amount of matter creates a large amount of energy... so there is little fear that we will run out of it
How does nuclear energy impact the environment?
Not much pollution unless there is a nuclear reaction.
How much nuclear energy is used in Indiana?
Indiana has no nuclear power plants.
How much percent of Saskatchewan uses nuclear energy?
There are no nuclear power plants in that province
Does hydro energy cost less then nuclear energy?
Yes much less
How much better or worse is nuclear energy?
Compared to what?
How much nuclear energy does Australia use?
In Australia they use no nuclear energy. They only have on reactor which is only used for medical purposes.
Does nuclear fusion produce much less energy per atom than nuclear fission?
Nuclear fusion produce energy 400 times more than nuclear fission for the same mass.
Describe the energy of nuclear fusion?
Nuclear fusion has not yet been achieved on Earth but it is the process by which the un and stars are believed to gain their energy. At the moment nuclear reactors use nuclear fission, which is the splitting of radioactive nucleii. Nuclear fussion is the combining, or the fusion, of atoms which would release much much more energy. Many scientists believe that this is the way we need to go to solve the energy crisis.
How much mechanical energy is in a nuclear bomb?
That depends on the yield.
