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, .
