Oxidation Number Quizzes & Trivia

I am going to use this Quiz to see if you fully understand the topic of Oxidation and reduction. you are gonna take this quiz after my presentation. . . Its easy trust me. afterwards, I will grade each one of you out of 100. Good Luck! :)


Questions and Answers
  • 1. 
    • A. 

      Oxidation- the loss of electrons by atom or ion/ the gain of oxygen, Reduction- the loss of oxygen/ the gain of said electrons.

    • B. 

      Oxidation- the gain of electrons by an atom or ion/ loss of oxygen, Reduction- the gain of oxygen/ the loss of electrons by atom or ion.

    • C. 

      Oxidation- something having to do with oxide, i don't care -__- Reduction- something's being reduced, but i don't know what.

  • 2. 
    Can oxidation and reduction occur without one another? 
    • A. 

      They are interdependent

    • B. 

      They are not interdependent.

  • 3. 
    • A. 

      Its a combination of Reduction and Oxidation, when one occurs, the other does not.

    • B. 

      It is not a combination of reduction and oxidation , when one occurs, the other must occur as well.
