How do you write redox reactions. I was given this equation below:

2Mg + O2 --> 2MgO

I have to write the redox reaction

  • Chem -

    Do you want the two half equations; one for the oxidation and the other for the reduction?
    Mg ==> Mg^+2 + 2e
    O2 + 4e ==> 2O^-2

  • Chem -

    if I add them together they become the redox reaction?

    I think DrBob is right here they are after the two half reactions. It is already a redox reaction.

  • Chem -

    My teacher adds the 2 half reactions. What is that called?

  • Chem -

    In my opinion it is called the equation or chemical equation. It just happens to be a redox equation

    thanks :)
