4Fe + 3O2à 2Fe2O3 is a balanced equation. What is the charge on each iron (Fe) ion in hematite (Fe2O3)?
2 answers:
<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
Oxidation state is the number which is assigned to an element when it gains or looses electrons. If the element gains electron, it will attain a negative oxidation state and if the element looses electrons, it will attain a positive oxidation state.
We take the oxidation state of iron atom be 'x'.
Oxidation state of oxygen atom = -2
Evaluating the oxidation state of iron atom in :
Hence, the correct answer is Option C.

Explanation:
what you have to do is to multiply the given grams with the ratio of grams of that certain element in it's full compound in order to isolate the compound and get the element.
because the question did not specify how many grams of NO2 is formed, we can assume that the mass is neglegible, thus 1 mole was assigned to Nitrogen.
