Cu2+ cause that was easy, um, I screwed up the hexane one, I said C6H12 instead of H14, I did the um, cobalt? hydroxide one, uh, boron trichloride and something, etc etc.

I think I got the 5 reactions, we had a reaction quiz worth about 1/2 a multichaper test every other week (which I get about 1/2 of the reactions = C- on) so we got to know then quite well. Err, most of us did, I was too lazy to memorise all of the weird ones. good thing you only need to know 5...
I did the % comp of the C/H/N/O problem since it was just too easy to pass up (and I suck at thermo), and the element Q since the other one seemed confusing

5, and 760 on SAT2 (took it last year).
After the test, our AP chem class quickly became useless. We had a rocket lab. Some things to note... Safety precautions are "different" with Mr. Hatch (name changed to protect the awesome). In particular:
With most groups of rocketeers, the person launching stands as far back as the cord will allow, and everyone else is lying on the ground. With Mr. Hatch's class, we're all about 7 or 8 feet in a semicircle standing around it.
With most groups of rocketeers, the person launching checks that the area is clear, and counts down from 10, then carefully hits the button. With Mr. Hatch's class, the person launching does a cursory examination to make sure that the person connecting the wires is clear (but mainly because they're the only holding the safety key), yells "FIRE IN THE HOLE!", and hits the button.
With most groups of rocketeers, only well-formed rockets are launched. With Mr. Hatch's class, we spent two class days and a lab block building these; it would be a waste not to launch them! Who cares if they only have one fin?
Really, it's not as unsafe as it sounds; those motors haven't much thrust, and by the time they'd hit us, they wouldn't've built up much speed.
You can see a video of the resulting doom (and hear Crazy Mr. Hatch's laugh!) on my site.
Other fun labs were the silver beaker lab and the ice cream lab. I have photos/video of the silver beaker lab if anyone's interested...
