Question

Although fusion is an energetically favorable reaction for light nuclei, it does not occur under standard conditions on Earth because:


fission reactions are always favored over fusion reactions

a large amount of energy must be invested into the reaction before it can occur

atoms on Earth are generally too large to participate in fusion reactions

fusion reactions usually do not produce sufficient energy to make them worthwhile

Answer 1

a large amount of energy must be invested into the reaction before it can occur

Answer 2

Which of the following statements about FUSION is correct?


It is not a naturally occurring process.

It is currently used as a source of commercial energy production on Earth.

It can create heavier elements, like oxygen and nitrogen, from hydrogen and helium.

It is similar to radioactive decay in that it occurs on its own without stimulation.

Answer 3

It can create heavier elements, like oxygen and nitrogen, from hydrogen and helium.
it occurs in sun naturally...
