Which aspect is similar in both chemical and nuclear reactions? a. both involve nuclear fusion. b. both involve nuclear fission. c. both may release heat and light. d. both involve the exchange of electrons.

Hi!

The correct answer would be C

The key difference between the two types of reactions is that nuclear reaction involves a change in the nucleus of the atom(s) involved in the reaction, where as atoms in chemical reactions do not undergo any change in their nucleus.

Option A and B both deal with characteristics that pertain to only nuclear reactions, as both nuclear fusion and fission involve a change in the nuclear state of the initial elements.

Option D deals with the characteristic that pertains only to chemical reactions, which involve the transfer -gain or loss of electrons.

However, both of these types of reactions may be exothermic, with the capacity to release this energy as light, or heat.

Hence, Option C is correct

Hope this helps!

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
