A scientist student proposes a laboratory experiment to combine nuclei of krypton -96 (96 36 kr
and barium-139 ( 139 56 Ba), along with neutrons, to form uranium -235 (235 92 U). The
experiment is highly unlikely to be successful because
A. the threshold energy of the reaction is extremely high
B. the reaction energy is a positive value that is extremely high
C. the reaction energy is essentially zero
D. uranium-235 has a long half-life
Each fission in a nuclear reactor provides 200mev. How much uranium-235 has to undergo fission per unit time to provide 2000mw of thermal power? Let 1u=1.6605 x 10^-27 kg and m_p=1.00727u
A.3.2mg
B.2.0mg
C.2.5mg
D.3 5mg
