Answer 1

Go to the college board website. Then go to the purple box that says student, and click on that. this willl bring up a new page. Under the box that says college board tests (near the top), click on AP. This will bring you to a new page. Go over to courses and exams, and select Chemistry as the subject. This will bring up a new page. On the sidebar, select samply questions and scoring. This will bring you to a page that has the scoring guidelines for every AP Chemistry free response exam since 2004. The first list of exams that goes farther back just has the questions, but under the scoring guidelines section you can see the answers for the questions plus explanations. Click on the 2006 Scoring Guidelines link. (Not the 2006 Form B, you have the regular one).

It will bring up a pdf that has all of the answers for 2006 AP Chemistry free response section, and how they got them. For this specific question, go down to the last page, and it will be there. I use the college board scoring guidelines for explanations for any of the recent AP Chemistry exam questions. It's a great resource for learning the material.
