[填空题]
1.The following reaction takes place in rkwx ,0p:nseu vx+l 3ay1/ +nea nu/ex lph19o)vv/x:guqm7 * pkoclear reactor:
$^{235}_{92}U$+$^{1}_{0}n$→$^{144}_{56}Ba$+$^{89}_{36}Kr$+$3^1_0n$
(1)Differentiate between fission and fusion reactions.
(2)Determine whether this reaction is a nuclear fission or nuclear fusion.
2.The following data is given for this reaction:
The binding energy per nucleon of $^{235}U$ = 7.59 MeV
The binding energy per nucleon of $^{144}Ba$ = 8.27 MeV
The binding energy per nucleon of $^{89}Kr$ = 8.62 MeV
Calculate the energy released from this reaction. ΔE = MeV
