My teacher gave me this (http://www.chemmybear.com/groves/apch19_ncho.pdf) worksheet to do to prepare for the test tomorrow, but no answer sheet. Can someone please help me?

Type out the ones you're having problems on, and how you tried to solve them, and what answer you got, and we'll try to help.

The ones I'm having trouble with are NChO 1999 #4, (I got C for that one), NchO #40 (Got A for that one), NChO 1998 #39 (I got A by setting Ksp = - [2x]^2 and making x=.0013), and also I can't get NchO 1997 # 5.
That's all , just wanted to confirm my answers raelly:)

From this chart predict which will precipitate out (NchO 1997 # 5.)
