Question

Review Constants | Periodic Tat When a 99 U nucleus is bombarded by neutrons (n) it undergoes a fission feaction, resulting in the formation of two new nuclei and neutrons. The following equation is an example of one such fission process: U + n-Ba + Kr + 3on Enter the isotope symbol for the barium (Ba) nucleus in this reaction. Express your answer as an isotope. View Available Hint(s) - AED mo? Submit Part B In another process in which undergoes neutron bombardment, the following reaction occurs U + n^4Sr +4 Xe + 3n Enter the isotope symbol for the strontium (Sr) nucleus in this reaction Express your answer as an isotope.

Answer 1

PART-A 235 t 2 u 92 n 0 A 94 Ba + kr + 3 Z 36 m 0 In balancing should balance of nuclear reaction, atauic no and we мо по first atauic no Let us balance Sumot atawić no't of reactants - Sun Cit atau no of products, 92+0 = 2+36 +3(0) 92 = 2+36 a) za 92-36 -56, the Alanis no at Ba isi 56, let us belauce mass no Suun muass mo's of reactanti = Sumat - mase ao at products,

235+1= A +94+3(1) 236 = A +97 a) A = 236-97 = 139, mass no of Ba is: 139, 139 Ba - Isotope of Barium PART-B A ut n 92 o 143 srt xe t3n 54 2 firar etruir nos let us belancé 92 +0= 2+5473(0) - 92= 2+5440 os 2-92-54= 38, Let us belauce now mass no 235+1= A +43 +300 7) 236 = A +1437] -> A=236-146 = 90 90 sr die Isotope is
