Aluminum metal reacts with oxygen gas (O2) to form aluminum oxide.


a. Write a balanced equation for this oxidation-reduction reaction. (In this problem you need not worry about the physical state of the reactants or product.)

2Al+3O2=2Al2O3

b. which reactant is oxidized?

O2

c. Which reactant is being reduced?

Al

d. What is the oxidizing agent?

Al



e. What is the reducing agent?

O2

    None are right including the equation. it isn't balanced.
    Oxidation is the loss of electrons.
    Reduction is the gain of electrons.

    This site is a good redox site.

  • chemistry - ,

    4Al+3O2=2Al2O3

    O2 is being oxidized

    Al is being reduced

    Al is the oxidizing agent

    O2 is the reducing agent

    Second time through is right on all.

  • chemistry - ,

    Im confused still for the first question
