Petrochemicals are separated into 3 groups: Olefins, Aromatics, and Synthesis Gas.
Olefins: Ethelyne (Plastic Products), Propelyne (Plastic Products), and Butadiene (Synthetic Rubber)
Aromatics: Benzene (Dyes), Toluene (Polyurethane), and Xylenes (Synthetic Fibers)
Synthesis Gas: Ammonia (Fertilizer Urea) and Methanol (Chemical intermediate)
Reaction mechanisms will have a minimum of 2 or more steps
Answer:

Explanation:
Hello!
In this case, since we have 245 of iron (III) oxide, we first need to compute the moles contained there:

Now, as 1 mole of iron (III) oxide is related to 2 moles of iron, due to iron's subscript in the molecule, we get the moles of iron itself:

And the mass is computed based on the atomic mass of iron:
