In 1989, Two Prominent Electrochemists, Stanley Pons and Martin Fleischmann

In 1989, two prominent electrochemists, Stanley Pons and Martin Fleischmann, erroneously proposed that they had observed cold fusion, which was the term used to describe anomalously high energy generation associated with the electrolysis of deuterium oxide (D₂O or heavy water) . Calculate the energy released when deuterium nuclides (2.013553 u) combine to produce 1 mol of helium nuclides (4.001506 u) . (u = atomic mass unit)

B) 2 * 10⁷ kJ
C) 2 * 10⁸ kJ
D) 2* 10⁹ kJ
E) 2 * 10¹⁰ kJ
