Question

The effective 1 for the proton-proton cycle is express this as energy per kilogram of hydrogen

Answer 1

Answer:

Explanation:

Proton-proton cycle, also called Proton-proton Reaction, chain of thermonuclear reactions that is the chief source of the energy radiated by the Sun and other cool main-sequence stars. Another sequence of thermonuclear reactions, called the carbon cycle, provides much of the energy released by hotter stars.

In a proton-proton cycle, four hydrogen nuclei (protons) are combined to form one helium nucleus; 0.7 percent of the original mass is lost mainly by conversion into heat energy, but some energy escapes in the form of neutrinos (ν). First, two hydrogen nuclei (1H) combine to form a hydrogen-2 nucleus (2H, deuterium) with the emission of a positive electron (e+, positron) and a neutrino (ν). The hydrogen-2 nucleus then rapidly captures another proton to form a helium-3 nucleus (3He), while emitting a gamma ray
