Fe2O3(s) + 3CO(g) --gt; 2Fe(s) + 3CO2(g) ΔH -24.8 kJ The enthalpy change for the combustion of carbon monoxide is: 2CO(g) + O2(g) --gt; 2CO2(g) ΔH -566 kJ Use the preceding thermochemical equations to calculate the enthalpy change (in kJ) for the equation: 4Fe(s) + 3O2(g) --gt; 2Fe2O3(s) (Use 4 sig. fig.)
Pay attention in class and do your own homework. (:
