Question

Ottawa Nestoundland Toronto TE S Washington NORTH Nuclear Fission Reactions Nuclear fission, in which nuclei split into lighter nuclei, can be written in the form of nuclear equations such as the following. Since nuclear reactions conserve both number of nucleons (a nucleon is a neutron or a proton) and electric charge, both the superscripts and the subscripts must balance on the two sides of the equation, as in nổ+U22 - M042 +Sn58 +3 nó. 4. Determine the missing quantities '?' in the following nuclear reactions. Raz – 2,+He n+U – Xe 4+Srº +? n. The released neutrons, after they have slowed down sufficiently, can initiate further reactions. Therefore an avalanche of nuclear reactions may take place (as in nuclear reactors or weapons).

Answer 1

226 4 Razbunat Het equating balancing the number of nucleons and electir charge 226= mt4 m= 226-4 = 222 88 = n42 Th= 86 Hence moing quantity is (finger) not 125 yellot soos tynó Balancing both sides (1+235) = 140+94 +4(1) 236 = 234+ y fit 0+92 = 54+x+ y(0) x=692-54) = 38 Hence missing quantities are shy and ano
