Which statement correctly compares chemical reactions with nuclear reactions? a.) in chemical reactions, new isotopes are formed. in nuclear reactions, new compounds are formed. b.) chemical reactions can be represented by balanced equations. nuclear reactions cannot be represented by balanced equations. c.) in chemical reactions, small amounts of energy can be absorbed or released. in nuclear reactions, changes in energy are much larger. d.) in chemical reactions, only protons and neutrons are affected. in nuclear reactions, only electrons are affected.

The correct option is C.

During ordinary chemical reactions, energy may be released into the environment or absorbed from the environment. The type of chemical reaction that release energy into the environment is called exothermic reaction while the one that takes energy from the environment is called endothermic reaction. The quantity of energy released or absorbed during ordinary chemical reactions is always very small compare to the one released during nuclear reactions. There are two basic types of nuclear reactions, these are fission and fusion reactions. The energy released during these two processes are so great that they can be used to power the generation of electric current.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
