-43,764 kJ heat is released during the combustion of 8 moles of octane.
How to find the amount of heat released?
To calculate the amount of heat released in a chemical reaction, use the equation Q = mc ΔT, where Q is the heat energy transferred (in joules), m is the mass of the liquid being heated (in kilograms), c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius), and ΔT is the change in temperature.
from equation 2 moles = - 10,941 kJ
for 8 moles:
8/2 x -10,941 = -43,764 kJ
When octane is burned, carbon dioxide gas is generated, as shown in the reaction equation. This is typical of hydrocarbon combustion reactions, such as octane and propane.
