how can you tell whether an oxide is acidic, basic or amphoteric??

Re: H2O
Yes water is both amphoteric and amphiprotic because it reacts with both acids and bases, as well as donates and accepts protons.

Re: Conjugate Acids and Bases
Yes there will always be a conjugate acid and conjugate base so long as there is both an acid and a base.

Re: 9C.3D
aqua comes before oxalato, therefore it's still written in alphabetical order.
Re: 9C.1 a
You can use either cyano or cyanido, neither is more correct than the other.

Lone pairs result in repulsion from them, therefore decreasing the bonds angles.

Re: Polar vs. Nonpolar
It would be considered polar because of the dipole moment occurring between the central atom and chloride atom. You must take into consideration the differences in electronegativity.

I'm late at responding to this, but I know for this midterm I told myself I knew all the material before going in. I was able to successfully complete a practice exam prior to the official exam. Do some easy problems and just boost that confidence. Controlling your breaths also helps control jitters.
