Answer : The heat released by the combustion of 1.121 mol of hexane (kJ) is, 
Explanation :
The given balanced reaction is,

Given:
Moles of hexane = 0.121 mol
= -8326 kJ/mol
The negative sign indicate that the reaction exothermic or amount of heat released.
As, 1 mole of hexane released heat = 8326 kJ
So, 0.121 mole of hexane released heat = 8326 × 0.121 = 1007.446 ≈ 
Therefore, the heat released by the combustion of 1.121 mol of hexane is
