In the proton–proton chain,
a.
no neutrinos are produced.
b.
energy is released because a helium nucleus has a greater mass than a hydrogen nucleus.
c.
no photons are produced.
d.
carbon serves as a catalyst for the nuclear reaction.
e.
energy is produced in the form of gamma rays and the velocity of the created nuclei.
2. Assume that the entire luminosity of the Sun is due to the PP chain reaction. The complete
PP chain reaction converts 4 hydrogen nuclei into 1 helium nucleus, according to the following
reaction:
4 H - He + 2e* + 2v.
a. Estimate the amount of energy released by one complete reaction.
b. Estimate how many of these reactions occur per second in the Sun, and how many
neutrinos the Sun produces each second.
c. Estimate the flux of neutrinos (in v's s' cm?) passing through the Earth.
1. If 0.048 × 10-27 kg of mass is converted to energy in a single hydrogen fusion reaction, how much mass is lost over the lifespan of the sun?
