4E.5

[Bryce Ramirez 1J]

Can someone explain how to set up the calculations for solving the enthalpy using bond enthalpy. In part a of 4E.5 it has 3 C2H2 forms into C6H6, but I don't know how to find which bonds are actually used for calculating the net change.

Drawing out the Lewis structures will indicate the types of bonds. Also it may be helpful to memorize some of the organic compounds. C6H6 is benzene and has ring shape with alternating single and double carbon carbon bonds.

I typically draw out all of the compounds in the reaction and then observe which bonds must break in order to form those on the products side.

Hello,

Could someone explain how they got the answer for the forming bonds for part a? Thank you!!

You first must draw out all of the Lewis structures. Then count all the bonds on the left side of the equation and all of the bonds on the right side of the equation. Then do bonds broken- bonds formed.
