Choose all the correct information concerning chemical reactions: involves small amounts of energy. some of the mass is converted into energy. involves large amounts of energy. only electrons are involved. the mass remains the same. involves the nuclei of the atoms.

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.
