<p>june 25 i think they give curves only for qas and june isnt a qas month</p>
<p>about the same, not much difference</p>
<p>yea i think one of the keq’s was 1.0x10^50</p>
<p>Where do you find the curves? I didn’t know that they gave out what the curves were on tests at all. The scores come out on June 25th. Only 19 days! What time do they come out?</p>
<p>
</p>
<p>Are you talking about the one released in the big blue CB book? I took that practice test last week and thought it was significantly more difficult than the SAT today.</p>
<p>^i honestly thought it was extremely similar. one of the questions i swear was word for word from that book i think it was the one that had to do with the liquification of nitrogen…oh and 02 and 03 being allotropes was also an identical question</p>
<p>^ Yes</p>
<p>That’s bizarre because that released test has an extremely harsh curve, meaning that it’s an “easier” test. Maybe you felt today’s was easier because you had a week to prepare.</p>
<p>what was the acid rain one? combustion?</p>
<p>This is awesome. I scored a hellish 660 on the Barrons practice test but I’m pretty confident that I got 750+ on this test. Heck yes. I only skipped the ion question because I forgot whether or not Potassium turned acidic or basic in water.</p>
<p>For acid rain I had to put down neutralization. Because Acid is acidic, and it corrodes limestone, which is Ca.
CaCO3 (s) + H2SO4 (aq) is in equilibrium with CaSO4 (aq) + CO2 (g) + H2O (l)
But I was initially thinking OXIDATION, because it sounded familiar. I’m hesitant on this question.</p>
<p>^jamesford we might be the unlucky people who get just as harsh a curve but i wouldnt speculate about curves. they dont always turn out the way you would expect</p>
<p>
</p>
<p>Neutralization. Acid rain is acidic and limestone is made up of CaCO3 (a basic salt).</p>
<p>
</p>
<p>That might be it. I’d like to think all the studying paid off! There were just a few questions on the practice test that really stumped me and took me some time to understand. I didn’t really encounter many of those on today’s SAT.</p>
<p>This test is pretty easy, Im expecting 80+ to be 800.</p>
<p>25/6
confirmed</p>
<p>Trying to guess the curve doesn’t usually work out but it’s still interesting to get peoples’ opinions.</p>
<p>i have the 1998 edition collegeboard with a past collegboard exam where 800 was 78/85. I expect the curve of this exam to be similar since they were similar in difficulty(Actually our exam was harder).</p>
<p>I don’t really care about the curve, I just hope to get as many right as possible. The more you get right, the higher your score, no matter what the curve is.</p>
<p>I put down neutralization for the acid rain/limestone question. Acid rain is acidic, and lime has a basic pH (somewhere around 12, maybe a little less I think). It’s not really oxidation, since nothing changes charge.</p>
<p>K is neutral, but it bonds with OH- to form KOH.</p>
<p>the normal curve is 79/85 though
I’ve confirmed this from reading past threads lol</p>
<p>that means the answer was only OH- right? H2 can’t form if that was the case or can it? lol</p>
<p>H2 should form because the OH- is associated with the K+, so the H2 forms from the heat released by K blowing up</p>
<p>Alkali metals combine with water to form hydrogen gas. </p>
<p>K + H2O –> KOH + H2</p>
