Expert Solution
Step 1

The enthalpy change of the chemical reaction when two moles of Aluminium reacted completely is given as -852 kJ (negatove sign indicate energy is released).

Therefore to calculate the total energy released for 10.0 grams of Al, first of all calculate the moles of Aluminium constituted by10.0 g by using formula...

mole = mass / molar mass

where, molar mass of Al = 27.0 g/mol
