Each reation releases or absorbs a very large amount of energy per atom. a. chemical and nuclear reactionb. chemical reactions. c. no reaction d. nuclear reation

Option (D) is the correct answer.

Explanation:

A chemical reaction is defined as a reaction that involves exchange of electrons between the combining atoms. Not every chemical reaction releases or absorbs a very large amount of energy per atom.

On the other hand, a reaction that involves change in atomic nuclei of an atom either by splitting or combining of two atomic nuclei is known as a nuclear reaction.

For example,

Nuclear fission is a reaction in which a large nucleus splits by absorption of energy into two atomic nuclei. Nuclear fusion is a reaction in which two atomic nuclei combine together to result in the formation of a large atomic nuclei along with release of energy.

Each nuclear reaction releases or absorbs a very large amount of energy per atom.

Therefore, we can conclude that each nuclear reaction releases or absorbs a very large amount of energy per atom.  

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
