how much heat will be liberated if 37.8 g of Fe2O3 is allowed to react with 18.7 g of aluminum.

Fe2O3(s) + 2Al(s)--> Al2O3(s) + 2Fe(s) + 851.5kJ

    This is a combination limiting reagent problem with heat thrown in for good measure. What is the limiting reagent? How much Fe2O3 reacts?
    851.5 kJ x (g Fe2O3 reacting/molar mass Fe2O3) = kJ heat released.

    Thank you

    I checked to see which one is the L.R, which it is Fe2O3, then i converted grams into moles and then converted those moles in to heat released and got -201.5 kJ

    This is the first time i have been on here, if any one wants to confirm that is the correct answer, I would greatly appreciate it.

    Thanks again
