<p>I think I also got .05 </p>

<p>i also had 0.005 for another question don’t rmember which one though</p>

<p>0 Blank
2 Wrong</p>

<p>Given the amount of simple mistakes I make (would’ve had an A+ in AP Chem instead of an A-), my chances at an 800 are looking pretty slim.</p>

<p>easy test but harder than the Collegeboard practice test.</p>

<p>.005 for the question about the amount of PbI2 that precipitated from the solutions.</p>

<p>I think the ion balancing was 2</p>

<p>2 wrong
2 blank</p>

<p>I think I can still get an 800, but I highly doubt I’m going to get it. I’m looking at 750+</p>

<p>ya i’m sure i put 0.5 but does anbody else remeber putting
0.005 or something for another question??</p>

<p>did anyone get a 2:3 ratio for one of the balancing?</p>

<p>yeah i had .005 for the PbI2 solid percipitating</p>

<p>yeah, 2:3 for Al:S</p>

<p>what about the question on the isomers for the t/f section: was it T T ce?</p>

<p>wow really I’m sure I guessed 2 lol for the ionic question</p>

<p>isomer question was TTCE</p>

<p>Did good on Chem! Unlike Math II, I’m confident I at least got over 700. :D</p>

<p>yettiddqq8: Yeah I got a 2:3 ratio for one of the questions. I forgot what it was exactly, but I remember that being an answer.</p>

<p>ya i got 2:3. I just switched their oxidation numbers.</p>

<p>I thought the isomer was FT i dunno though</p>

<p>damn i got the isomer question wrong</p>

<p>anyone remeber the first T/F question???</p>

<p>for the isomers they both had the same number of carbons and hydrogens but they were just arranged differently so i think that would be isomers</p>

<p>how to separate iron fillings and silicon? is that magnets and cardboard, i just guessed</p>

<p>They were isomers because they had the same number of carbon and hydrogen atoms.</p>

<p>ya.</p>

<p>Can someone explain the K + H20 question</p>

<p>yes. Magnets and cardboard was the only answer that made any sense.</p>
