Query: Can't believe this book made it to print

I too was disappointed with this book!I'm currently prepping for a chemistry placement exam and was shocked to find this book so poorly written. I haven't touched chemistry in over eight years but even I knew Gadolinium is Gd, not Ga (which is actually Gallium); that basic math dictates when P1*V1/T1 = P2*V2/T2, solving for V2 yields V2=(P1*V1)T2/(T1*P2) and NOT V1*T1*P1 = V2*T2*P2; and that when an atom is stripped of an electron, a CATION is formed (losing an e- means a POSITIVE charge).Right around Chapter 8's section on Ions and their naming system is when I gave up on this book. Confusing and just as thin as the earlier segments -- which would be fine, except these concepts require WAY more meat to understand than the earlier chapters -- and way more RELIABLE meat. I know this book is just a brush-up, but if they can't explain these ideas simply then they shouldn't have written the book at all!Bad bad bad. Buy something else.
