How does a nuclear reaction differ from a chemical reaction? entropy is increased in a chemical reaction while it is decreased in a nuclear reaction. in a nuclear reaction, the elements change identities while in a chemical reaction they do not. in a chemical reaction, elements are created and destroyed while all elements are conserved in a nuclear reaction. entropy is increased in a nuclear reaction while it is decreased in a chemical reaction. there is no actual difference between the two reactions except that a nuclear reaction emits radiation while a chemical reaction emits heat?

One of the hopes for solving the world's energy problem is to make use of the fusion reaction 21h +31h --> 42he + 10n + energy how much energy is released when 1 mol of deuterium is fused with 1 mol of tritium according to the above reaction? the masses of the atoms and the neutrons are as follows: 21h = 2.0140 amu 31h = 3.01605 amu 42he = 4.002603 amu 10n = 1.008665 amu. the speed of light is 2.9979 x 108 m/s.
