Iron ore haematite (also spelled hematite) contains iron(III) oxide. Iron can be extracted from iron(III) oxide using a blast furnace according to the following reactions:
C (s) + O2 (g) → CO2 (g)
CO2 (g) + C (s) → 2 CO (g)
Fe2O3 (s) + 3 CO (g) → 2 Fe (l) + 3 CO2 (g)
Calculate the mass (in kg) of solid carbon required to obtain 100 kg of iron.
