An egg cooking on a campfire is an example of a. only an exothermic reaction. b. only an endothermic reaction. c. an endothermic and an exothermic reaction. d. neither an exothermic nor an endothermic reaction.

Answer : The correct option is, (B) only an endothermic reaction.

Explanation :

Endothermic reaction : It is a type of chemical reaction in which the energy is absorbed from the surrounding.

Exothermic reaction : It is a type of chemical reaction in which the energy is released into the surrounding.

From the this we conclude that, the energy is added or absorbed during the egg cooking on a campfire. That means, it is an endothermic process.

Hence, the correct option is, (B) only an endothermic reaction.

you should have at least 5 complete sentences with a main idea and supporting details.  

you must include the following words:  

potential energy

kinetic energy

mechanical energy

conservation of energy

dude, this is hard lol : ))

atomic = no of protons.

mass number-atomic number = neutron number
