<span>You must multiply the bond enthalpy by each broken or formed bond.
The C - H bond = 414k Joules/ mol, but that is only applicable per bond.
The C3H8 molecule has 8*C-H bonds that have to break. You have to account all the bonds that break and form to get the DH for the reaction.
Because of the Lewis structure of Propane C3h8 you only use 8 in </span><span>c3h8 has 3-C and 8-C.</span>

Answer: C - B - A - D
Explanation:
-Obtain a flask that is thoroughly cleaned
-Add the desired amount of stock solution
-Add deionized water until the volume reaches the mark on the flask.
- Cap the flask and invert several times to thoroughly mix the solution.
<span>When you eat breakfast in the morning, your body digests that food and breaks it down. This of course requires a chemical reaction. Hope this helped!</span>
