In the same reaction, one substance loses oxygen and another gains oxygen. What is it called?

Answer and explanation

Correct answer: Redox reaction

Oxidation and reduction occur together in a redox reaction. Loss of oxygen is reduction, while gain of oxygen is oxidation. Therefore, if one substance loses oxygen and another gains it during the same chemical change, the process is called a redox reaction, making option B correct. Precipitation concerns formation of an insoluble solid, whereas evaporation and melting are physical changes and do not describe oxygen transfer.
