Here's a good chemistry question:
Why isn't H2O written as OH2?
Why isn't C6H12O6 written as H12C6O6 or O6C6H12?
Why isn't ... you get the idea.
Why are compounds written as the way they are?
Thanks for all answers!

where can you tell which region the maximum buffering occurs? Also where on the curve does the ph only depend on the acetate acid (NaOH is being titrated into acetate acid)? and where does the pH only depnd on the excess strong bases added?

The entropy change for complex formation is more favorable when the ligand is chelating.
The enthalpy change for complex formation is more favorable when the ligand is chelating.
The complex is less likely to be oxidized when the ligand is chelating.
A coordination number of six can be obtained with a chelating ligand, but only four-coordinate complexes are possible with monodentate ligands.

I can't find anything in my book that relates to this.
