Question

2Al(s) + Fe2O3(s) → Al2O3(s) + 2Fe(s) The ΔHf for Fe2O3(s) = -824.3 kJ/mole. The ΔHf for Al2O3(s) = -1675.7 kJ/mole. Finish the equation. ΔHrxn = [(1)( kJ/mole) + (2)( kJ/mole)] - [(1)( kJ/mole) + (2) ( kJ/mole)]

Answer 1

2als is the answer i believe good luck

Answer 2

ΔHrxn = [(1)( -1675.7 kJ/mole) + (2)( 0 kJ/mole)] - [(1)( -824.3 kJ/mole) + (2) ( 0 kJ/mole)]

Hope this helps :)
