Use the following equation to determine the charge on iron when it dissociates from oxygen and determine whether it is being oxidized or reduced:

Fe2O3 + 3CO -> 2Fe + 3CO2


A. It starts with a charge of +3 and is reduced.
B. It starts with a charge of +2 and is reduced.
C. It starts with a charge of -2 and is oxidized.
D. It starts with a charge of -3 and is oxidized.

Respuesta :

The correct answer is A. Brainliest would be much appreciated.

The oxidation state of [tex]Fe_2O_3[/tex] is +3. The bond formation between oxygen and iron depends on the difference in electronegativity between these two atoms. It starts with a charge of +3 and is reduced. Hence, option A is correct.

What is the oxidation number?

The total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.

Oxygen in nearly all cases has a charge of 2−, so the total ionic charge the O atoms exhibit is 3(−2)=−6 .

If two Fe atoms equalize this charge and make it neutral, the charge (oxidation state) of Fe in this compound must be 3+.
