June SAT: Chemistry Post-Test Discussion

Test Preparation SAT Subject Test Preparation
1

<p>I don't think there's a thread for this yet, so i decided to make it (:
Let's discuss questions on here after the embargo's been lifted!</p>

2

<p>I skipped 12…
The rest of the 73 seemed easy
Hope I got them right</p>

3

<p>it definitely wasn’t a hard test, but i didn’t have enough time to do 4 :(</p>

4

<p>How many can you miss for 800? I omited two and probably missed 2 or 3 more.</p>

5

<p>I dont know how many I missed, I do know that some of them were easy
Can we discuss the questions now?</p>

6

<p>K, I’ll start off. The balancing question with CO3 somewhere and CA+2 and H2O and CO2, it asked for one of the coefficients. I think the answer was D/a coefficient of 4, but I can’t remember the whole reaction.</p>

7

<p>@giants: I recall it being 1 or 2…</p>

8

<p>Is the embargo lifted?</p>

9

<p>as do I
sounds familiar</p>

10

<p>ahh the questions actually weren’t that hard, but I freaked out. first SAT test ever. ah well, I’ll at least I’ll never make that mistake again. lesson learned. just hoping for 700+…</p>

<p>and I second hardworking21’s question</p>

11

<p>There were two balancing questions…one was one and the other was two…</p>

12

<p>when my proctor called out ‘5 minutes left’ i flipped
i had to go faster
if i dont get a 750 i want at least a 700
okay so umm any questions about the test
btw does the curve for a specific SAT II change?</p>

13

<p>Yeah the curve changes. The easier the test the harder the curve. I thought this was easier than the practice tests that I took, so it might be a harsher grading scale.</p>

14

<p>…■■■
umm so chromiun(VI) to Chromium
was the reduction?</p>

15

<p>@shoumik95
that’s what i got</p>

<p>what was the answer about iodide crystals + purple vapors? i put sublimination</p>

16

<p>I got sublimation twice on that section. Was limestone oxidation? More rust on iron was due to surface area (CE)?</p>

17

<p>me too
someone showed me a video when i asked
an iodine normally sublimes so yea
oh and for solid C–>CO2 gas
that was the sublimation too
and for the last question was that heat of sublimation?
and what did u get for the first four lab procedures?</p>

18

<p>Yep,</p>

<p>Chromium(VI) reduces to become chromium.
Iodine crystals sublime to form purple vapor (Iodine gas).</p>

19

<p>Acid rain on limestone was neutralization. Limestone is basic…</p>

20

<p>What do you guys think the curve is gonna be?</p>
