### Redox and Nuclear Chemistry Problems #### Question 25 With respect to the following unbalanced redox equation that takes place in basic solution: \[ \text{MnO}_2(s) + \text{V}^{2+}(aq) \rightarrow \text{VO}_3^{-}(aq) + \text{Mn}^{2+}(aq) \] The stoichiometric coefficient on VO₃⁻ (aq) will be: - (A) 1 - (B) 2 - (C) 4 - (D) 6 - (E) 12 #### Question 26 When plutonium-239 is bombarded with a neutron, it produces xenon-137, zirconium-95, and releases eight neutrons. This fission event results in a mass defect of 1.93956 amu. How much energy is produced when 1.737 x 10⁴ g of plutonium-239 (above the critical mass) are bombarded with neutrons? - (A) 7.629 x 10²⁴ J - (B) 4.377 x 10²⁵ J - (C) 3.221 x 10¹⁶ J - (D) 3.028 x 10²⁸ J - (E) 1.267 x 10¹⁶ J
