15. When two deuterons, ; H, combine to form a helium nucleus, approximately 24 Me V of energy is released. A possible explanation for the release of energy is that the helium nucleus immediately breaks apart when two deuterons are combined A. two deuterons have a smaller total mass than that of the helium nucleus B. two deuterons have a greater total mass than that of the helium nucleus C. electrons are more tightly bound to the helium nucleus than they are to a D. deuteron nucleus Use the following information to answer the next four questions Nuclear Reaction Equation 25Utin - 's6 Ba + _?_+ 3in + energy masses of particles 35 U = 3.902997 x 10-25 kg euston = 1.675 x 10-27 kg 144 Ba = 2.389801 x 10-25 kg ? = 1.476501 x 10-25 kg 16.
