hello all.
first time to the forum..lookin for help on the last question of an assignment i have due for tomorrow but i'm stumped..

Aluminum is used as a structural material on ships because it is very light. Warships encountered a problem with aluminum. When a ship was hit with a missle, a  fire ensued that was very difficult to put out and produced a deadly waste gases. The aluminum structure itself would burn! How much heat energy is released when each 1000 kg of aluminum in a ship reacts with oxygen to produce aluminum oxide? When you express your answer as a scientific notation number (a x 10^b) in kJ, write the value of "a" correct to 3 signifcant digits in the answer box.

_ _ _ _ x 10^7 kJ

I think there must be more information somewhere.

Can you write the equation representing this reaction?

IMHO you are supposed to find out necessary thermodynamic data on your own. In real life you will be searching for the data on a daily basis, so I hope your diploma exam will check if you know how to do it
