Below is the thermochemical equation for the combustion of octane How much heat is released during the combustion of 8 moles of octane C8H18 Question

Answer :

-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.
