Iron can be extracted from the iron(III) oxide found in iron ores (such as haematite) via an oxidation-
reduction reaction with carbon. The thermochemical equation for this process is:
2 Fe2O3(s) + 3 C(s) 4 Fe(l) + 3 CO₂(9) AH° = +467.9 kJ
How much heat (in kJ) is needed to convert 607 g Fe2O3 into pure iron in the presence of excess
carbon?
kj
When 2.33x107 kJ of heat is added to Fe2O3 in the presence of excess carbon, how many
kilograms of Fe can be produced?
kg
