**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 10¹² 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

In Question 25, the given problem focuses on finding the stoichiometric coefficient for VO₃⁻ (aq) in an unbalanced redox reaction equation. The solution involves balancing the reaction in a basic medium.
In Question 26, the problem addresses a nuclear fission reaction involving plutonium-239. To solve it, one must consider the mass defect and use Einstein’s equation \(E = mc^2\) to find the energy produced during the fission process. The mass defect is provided in atomic mass units (amu), and the problem requires converting this to energy in joules.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc0633024-a4bc-4f66-b9e9-fd2e8bdcc354%2Fd2822327-ccd6-47e8-9919-16775ba89846%2Fgesoa9c_processed.jpeg&w=3840&q=75)
