Final answer:
The student's query involves the chemical reduction of iron oxide to produce iron, illustrating a redox reaction; calculating the grams of SO3 needed for a reaction with Fe2O3 also forms part of the question.
Step-by-step explanation:
The question posed appears to be related to the reduction of iron oxide (Fe2O3) and the chemical processes involved in the production of iron from its ore using different reducing agents like carbon monoxide (CO) or carbon (C). In the reactions provided:
- 3Fe2O3 + CO → 2Fe3O4 + CO2
- Fe3O4 + CO → FeO + CO2
- 2Fe2O3 (s) +3C (s) → 4Fe (s) +3CO2 (g)
The last equation demonstrates the reduction of iron oxide to iron while carbon is oxidized to carbon dioxide. This simultaneous oxidation and reduction indicate a redox process.
To answer the question regarding the reaction of Fe2O3 with SO3 to produce iron (III) sulfate (Fe2(SO4)3):
Fe2O3 +3SO3 → Fe2(SO4)3
If you have 3.59 mol of Fe2O3, to calculate the grams of SO3 required, use the molar ratios from the balanced equation and the molar mass of SO3 for conversion.
