7,004,224 kilo joules of heat is released


2735 kilo joules of heat is released


87,528 kilo joules of heat is released

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 4 options class=

Respuesta :

from equation 2 moles = - 10,941 kJ

for 8 moles:

8/2 x -10,941 = -43,764 kJ

-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.
