Extracted text: 5. Pyrite is reacted with oxygen (O2) to produce hematite (Fe2O3) and sulfur dioxide (SO2). If 100 kilogram of pyrite is reacted, please calculate; a) Moles of hematite formed, b) Moles of sulfur dioxide formed, c) Volume of product gas when stoichiometric O2 is used, d) Volume of product gas when 50% excess air is used.
