Nuclear fission describes a nuclear reaction in which a heavy nucleus, such as uranium, is bombarded by neutrons causing the atom to split into two or more smaller atoms. The fission reactions take relatively little energy input to occur and do not occur in nature. Fission produces many highly radioactive particles and releases large amounts of energy. Predict the changes in the nucleus as uranium-235 is split in a nuclear reactor.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

l dont know l am s sorry

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
