Unformatted text preview: 2+ , was titrated with 0.100 M MnO 4-(aq). The end point (color change from light yellow to purple) was reached after 11.35 mL of MnO 4-(aq) was added. The products of the titration were Sn 4+ (aq) Mn 2+ (aq). How many moles of stannous ions were present in the original solution? Ex6. i . For the following fission process, what is the product A ? 239 94 Pu + 1 n --------------> 142 58 Ce + 4 -1 e + 3 1 n + A a. 95 36 Kr b. 140 53 I c. 235 92 U d. 56 26 Fe e. 95 40 Zr ii. The key energy-producing nuclear process in a thermonuclear weapon is: a. The fission of 239 94 Pu. b. 6 3 Li( 2 1 H) ----> 2 4 2 He c. 238 92 U + 1 n ----> 239 94 Pu + 2 -1 e d. 2 1 D + 2 1 D -----> 4 2 He e. 2 56 26 Fe + 2 1 n ----> 114 52 Te 2...
