What are the oxidation numbers of Fe and O in the compound Fe2O3?
A
Fe: +2, O: -3
B
Fe: +3, O: -2
C
Fe: +3, O: -1
D
Fe: +2, O: -2
Verified step by step guidance1
Recall that the oxidation number of oxygen (O) in most compounds is typically -2.
Let the oxidation number of iron (Fe) be represented as x.
Write the equation based on the fact that the sum of oxidation numbers in a neutral compound is zero: \$2x + 3(-2) = 0$.
Simplify the equation: \$2x - 6 = 0$.
Solve for x to find the oxidation number of Fe: \$2x = 6\( which gives \)x = +3$.
