The 3 methods

[Rafsan Rana 1A]

I forgot to write it in my notes, but which of the three methods was supposed to be the least accurate?

[Julie Park 1G]

Using bond enthalpies is the least accurate method because they are represented by averages from many different molecules (method 2)

[CalvinTNguyen2D]

Using bond enthalpies is going to be the least accurate, since bond enthalpies are found from an average of multiple different molecules.

[Jacob Villar 2C]

Bond enthalpies, since it is taken from the average of multiple molecules.

[Alison Trinh 1E]

Why is it necessary to know all three methods?
