Calculate the amount of heat released in the combustion of 11.5 grams of Al with 3.9 grams of O2 to form Al2O3(s) at 25°C and 1 atm. Δ HfAl2O3(s) = - 1676 kJ/mol HINT: What does Δ HfAl2O3(s) mean?
Enter a positive number since released implies a negative number already. Enter to 1 decimal place in kJ.
