What is the molecular formula of the structure below?
taurus [48]

Answer:

C₆H₆

Explanation:

Each border of the figure represents 1 atom of carbon. We have 6 borders = 6 atoms of carbon.

Each atom of carbon form 4 bonds. All the carbons are doing a double bond and a single bond with other carbons. That means are bonded 3 times. The other bond (That is not represented in the figure. See the image) comes from hydrogens. As we have 6 carbons that are bonded each 1 with one hydrogen. There are six hydrogens and the molecular formula is:

<h3>C₆H₆</h3>

This structure is: Benzene

How much heat is released when 75 g of octane is burned completely if the enthalpy of combustion is -5,500 kJ/mol C8H18
AnnyKZ [126]
<span>Enthalpy change is the total heat that is absorbed or evolved in a certain reaction that is being carried in a constant pressure system. It can be calculated by the product of the specific heat of the substance and the difference of the final temperature and the initial temperature. For this case, the enthalpy of combustion is given, so we simply multiply the amount of octane present to the enthalpy given to determine the total heat that is released. 

Heat = 75 g ( 1 mol / 114.23 g ) (- 5500 kJ / mol ) = - 3611.14 kJ

The negative sign in the calculated value represents that this heat is being released in the process.</span>
