Question

The CNO cycle produces energy by fusing

neon into magnesium and oxygen.
hydrogen into helium.
carbon and nitrogen into oxygen.
silicon into iron.

Answer 1

The CNO cycle is a set of nuclear reactions that occur in stars, specifically in hotter stars. It involves the collisions of carbon and hydrogen nuclei and ultimately leads to the formation of nitrogen, oxygen, and helium. The CNO cycle is the main source of energy for stars with greater than the Sun's mass.

Step-by-step explanation:

The CNO cycle is a set of nuclear reactions that occur in stars, specifically in hotter stars. In this cycle, carbon and hydrogen nuclei collide and undergo a series of reactions that eventually form nitrogen, oxygen, and helium. The nitrogen and oxygen nuclei do not survive but interact to form carbon again. This cycle is the main source of energy for stars with masses greater than the Sun.
