The following questions are all 1 question on my homework.
How did the charge of the Fe atoms change as they became Fe3+ ions?
Is the oxidation state of the Fe3+ ions real or assigned?
Which of the following explains why the charge of the Fe changed in the reaction above?
The neutral Fe atoms gained 3 electrons to become Fe3+. [0 + (-3) = +3]
The Fe3+ ions lost 3 electrons to become neutral Fe. [+3 - (-3) = 0]
The neutral Fe atoms lost 3 electrons to become Fe3+. [0 - (-3) = +3]
The Fe3+ ions gained 3 electrons to become neutral Fe. [+3 + (-3) = 0]
Reduction is the process of gaining electrons. Oxidation is the process of losing electrons. Did Fe undergo reduction or oxidation to become Fe3+?
Which of the following shows the half reaction for the Fe in the reaction above?
What was the oxidation state of the oxygen gas?
What is the oxidation state of the O in Fe2O3?
Is the oxidation state of O in Fe2O3 a real oxidation state or an assigned oxidation state?
What happened to the oxidation state of the oxygen atoms during the reaction?
Which of the following explains the change in the oxidation state of O?
Each neutral O gained 2 electrons to become -2. [0 + (-2) = -2]
Each O2- lost 2 electrons to become neutral. [-2 - (-2) = 0]
Each neutral O lost 2 electrons to become -2. [0 - (-2) = -2]
Each O2- gained 2 electrons to become neutral. [-2 + (-2) = 0]
Reduction is the process of gaining electrons. Oxidation is the process of losing electrons. Did O undergo reduction or oxidation to become O2- in Fe2O3?
Which of the following half reactions shows the reduction of O?
O2- + 2e- O4-
O O2+ + 2e-
O + 2e- O2-
O O2- + 2e-

0 goo ee 02 02Explanation / Answer
The charge of Fe atoms in Fe3+ ions is +3 . Since the Fe atoms have +3 charge in reactants side in the reaction and 0 in products side , it has got reduced .
The Charge on Fe3+ ions is real , which the Fe atoms have gained by losing three electrons from its atom.
Ans. d) Fe3+ ions have gained 3 electrons to become neutral Fe [ +3 + (-3) = 0 ]
Fe underwent reduction to become Fe , by gaining three electrons and becoming neutral from previously charged cation .
The oxidation state of oxygen gas is 0 .
The oxidation state of oxygen in Fe2O3 is -2.
The reaction must be specified in order to get the rest of te questions answered.
