Nuclear Reactions / Fission
The Fission Chain Reaction proceeds geometrically: 1 neutron _ 3 _ 9 _ 27 _ 81 etc.
1 Mole of U-235 (about 1/2 lb) produces 2 x 1010 kJ which is equivalent to the combustion of 800 tons of Coal!
Commercial nuclear reactors use fission to produce electricity....Fission [“atomic”] bombs were used in the destruction of Hiroshima and Nagasaki, Japan, in August 1945.
