Energy that is bound in the reactants of this reaction is ultimately transferred to the products in this reaction. That is, according to the first law of thermodynamics, if 20% of this energy is bound by the helium nucleus and 10% of this energy is bound by a free neutron, how much energy is
released in this reaction?
