<p>does CB base its curves on the diffuclty of the test?</p>
<p>Not sure, does the physics test involve a lot of math? If it doesn’t that I wonder why Chemistry has such a harsh curve.</p>
<p>Probably because so many people do well on it? Everyone in my school takes the subject test AFTER they’ve taken the AP class.</p>
<p>lol but i thought curves were based on the past 5 year’s test takers</p>
<p>coming back to the previous discussion:</p>
<p>the answer to the “heat of ____” is heat of fusion, not sublimation. </p>
<p>(From wikipedia)
"The standard enthalpy of fusion (symbol: ΔHfus), also known as the heat of fusion or specific melting heat, is the amount of thermal energy which must be absorbed or evolved for 1 mole of a substance to change states from a solid to a liquid or vice versa. "</p>
<p>solid to liquid and liquid to solid isn’t solid to gas…</p>
<p>i don’t even remember that question</p>
<p>the PbI2 question was definitely .005 moles.</p>
<p>while there were 2I’s, it doesn’t matter there was still .1 (or whatever number) moles of the compound, and it was the limiting if i recall. </p>
<p>the test was a serious joke though after a year of AP. if i get under a 750 i think id be upset.</p>
<p>Truth. 10 char</p>
<p>i didnt take the chem but i heard it was extremely easy (for AP chem kids) ii hope you all did well</p>
<p>It’s definately sublimation.</p>
<p>c(s) –> co2(g) is not sublimation.. it’s oxidation</p>
<p>c (+0) to c (+4)</p>
<p>co2(s) –> c02(g) is because same compounds and same oxidation numbers for everything</p>
<p>oh god… -2 is 800? CB is insane!! they’re so mean…
maybe i should have done physics…
i hope i get at least 700+ so that i don’t feel sorry for my parents…
i did this test after math iic, and i was so tired by then…
ugh my shoulder still hurts…</p>
<p>j/w is the curve relative…or fixed beforehand?</p>
<p>relative…hopefully a bunch of people took it and failed so my -7 is an 800 =D</p>
<p>I hope so too, Sapience!</p>
<p>hehehe “crash and burn mother fu****” muhahahahha</p>
<p>I was just looking over the thread when I noticed something that Princeton said. For the last T/F/CE question, I think the answer was just T/F.</p>
<p>I put down the same thing as you did but according to my friend, the second statement said linear IONIC bonds between the C-O of CO2. The bonds are covalent. -.-</p>
<p>wait so the curve is all relative?</p>
<p>hmm, so would you guys recommend to cancel is i missed like 7 or 8?</p>
<p>did it really say ionic?!</p>
<p>i seriously hope it didn’t.</p>
