Which occurs in a fission reaction?  Group of answer choicesEnergy is absorbed as a less stable element forms.A new heavier element is formed and energy is released.Energy is converted into mass and forms a heavier element.The nuclei of atoms are split apart and energy is released. Flag question: Question 12Question 121 ptsOne kilogram of uranium can produce as much energy as 16,000 kilograms of coal. Why is the energy output for uranium so much greater than the energy output for coal?Group of answer choicesUranium is more highly purified than coal.Uranium is a highly reactive metal that reacts violently with oxygen when it burns.Uranium undergoes fission and nuclear reactions give off more energy than chemical reactions.Uranium is extremely radioactive and gives off more electromagnetic radiation than burning coal. Flag question: Question 13Question 131 ptsWhich occurs in a fusion reaction between two atoms?Group of answer choicesEnergy is absorbed as a less stable element forms.A new element is formed and energy is released.Energy is converted into mass and forms a heavier element.The nuclei of the atoms are split apart and energy is released.
