Question

question 3
which of the following elements is most likely formed during a supernova?
carbon
helium
gold
question 4
what causes stars to release energy?
radiation from nearby stars
fission of heavy elements
fusion of hydrogen into helium in the core

Explanation:

Question 3

• Carbon and Helium are formed in the early stages of stellar evolution (like in main - sequence stars through fusion). Supernovas are responsible for the formation of heavy elements. Gold is a heavy element, and it is most likely formed during a supernova event.

• Radiation from nearby stars does not cause a star to release energy. Fission of heavy elements is not the process by which stars release energy (stars use fusion). Stars release energy mainly through the fusion of hydrogen into helium in their cores.

Answer:

C. Gold
