In Massive Stars,three Helium Nuclei Fuse Together,forming a Carbon Nucleus

question 9

Multiple Choice

In massive stars,three helium nuclei fuse together,forming a carbon nucleus.This reaction heats the core of the star.The net mass of the three helium nuclei must therefore be

• A) higher than that of the carbon nucleus.
• B) less than that of the carbon nucleus.
• C) the same as that of the carbon nucleus since mass is always conserved.
• D) the same as that of the carbon nucleus since energy is always conserved.
