When oxygen is removed from one substance and, in the same reaction, added to another substance, what is the reaction called?
Answer and explanation
Correct answer: Redox reaction
Oxidation traditionally means addition of oxygen, while reduction means removal of oxygen. If these two processes occur simultaneously in the same reaction, the reaction is called a redox reaction, meaning reduction and oxidation together. A precipitation reaction forms an insoluble solid, an exothermic reaction releases heat, and a displacement reaction concerns replacement of one element by another. Hence, option B is correct.
