Iron Oxide + Carbon (Ferric)

Ferric Oxide + Carbon ➜ Iron + Carbon Dioxide
2Fe₂O₃ + 3C ➜ 4Fe + 3CO₂

Fe₂O₃ = 2•55.85 + 48 = 159.7 g/mol
2Fe₂O₃ = 319.4 g/mol
3C = 3•12 g/mol
4Fe = 4•55.85 g/mol
3CO₂ = 3(12+2•16) = 132 g/mol

319.4 g of Fe₂O₃ + 36 g of C ➜ 223.4 g of Fe + 132 g of CO₂



Note:
Iron II is ferrous (forms +2 ions)
Iron III is ferric (forms +3 ions)
Iron VIII is ferrate (rare)
