Iron can be extracted from the iron(III) oxide found in iron

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(g) ΔHO = +467.9 kJ How much heat (in kJ) is needed to convert 765 g Fe₂O, into pure iron in the presence of excess carbon? When 7.86x107 kJ of heat is added to Fe₂O, in the presence of excess carbon, how many kilograms of Fe can be produced?
