The corrosion of rebar inside concrete structures is seriousissue for the safety and stability of bridges and buildings. Thechemistry of corrosion is complex, but a simplified chemical model(iron rusting) is: 4Fe (s) + 3O2 (g) ⟶ 2Fe2O3 (s) ∆H = −1.65 × 103kJ a) How much heat is released when 1.00 pound of iron rusts? b)If 6.25 × 104 kJ is released, how many kilograms of iron haverusted?
