Bond Energies to Enthalpy Change Problem | How to Solve in AP Chemistry

In this video, I explain how to take a table of bond energy data and calculate the enthalpy change of the reaction. I also go over a couple variations of this that can show up on the AP Chemistry Exam.

But where is the 4 from?

[@SiebertScience]

There are four O-H bonds that are formed when the water molecules are made.

Thank you so muchh,, I thought we use the coefficients of bonds to multiply the bond energies
