Question

5. During nuclear fission, great amounts of energy are produced from (1 point)
particle accelerators.
tremendous amounts of mass.
a series of chemical reactions.
very small amounts of mass.

Answer 1

very small amounts of mass (being converted to large amounts of energy). Large unstable nuclei split apart into more stable nuclei (sometimes taking multiple steps to get there) and give off x-rays, gamma rays, neutrons, alpha particles, beta particles, etc. What you get depends on what you split :-)
