Explanation:
Answer : The amount of energy evolved during the reaction is,
.
Solution : Given,

Mass of Al = 51.2 g
Molar mass of Al = 27 g/mole
First we have to calculate the moles of Al.
The balanced combustion reaction is,

From the given reaction, we conclude that
As, 2 moles of Al evolved energy = 
So, 1.896 moles of Al evolved energy = 
Therefore, the amount of energy evolved during the reaction is,
.
