Achieve 6A.13

I was hoping someone can confirm my answers are correct, and my explanation. My answer key only provided the Lewis structures not whether they were a lewis base or lewis acid.

a) NH3 -- Lewis base, lone pair can be donated
b) BF3 -- Lewis acid -- can accept a pair of e-
c) Ag+ -- Lewis acid -- can accept a pair of e-
d) F- -- Lewis base -- can donate a pair since it has the negative charge
e) H- -- Lewis base -- can donate its pair since it has the negative charge

This is correct. When the F and H have a negative charge, then it is favorable for them to remove their electron pair, thereby acting as a Lewis base.
