Heat of formation.
« on: December 04, 2020, 05:35:40 PM »
I've been trying to find what the circle with a line through it means? What does that symbol represent? What is it called?

Update: I already found the answer to my question but I can't figure out how to delete the post.

No need to delete or edit your post. Why don't you add what you found, to help future people who may have the same question?

Good point. I found that it's called a "superscript" and it indicates that the ΔH is happening under standard conditions. ΔH by itself indicates the change in enthalpy has happened under non standard conditions. Also, ΔH° and subscript C indicates a combustion reaction with oxygen, and stands for "combustion".
