<p>So, now that the SAT is over. I was wondering, how did the test go. I honestly, thought it was going smooth but then now I'm not sure. Maybe, I'm thinking like I did okay, but in reality is screwed it up. Don't really know.</p>

<p>Also, the T/F question about butane being released when mixed with water. Is it true or false.</p>

<p>Also, all chlorine atoms are not identical because of isotopes correct?</p>

2

<p>Having just taken a Barron’s test yesterday and doing well on it, I found myself thinking “what the ****?” constantly throughout this test. Many of the things on the test I had not seen before, even though Barron’s is supposed to be in depth. I omitted six. </p>

<p>I don’t really remember the above questions. Got any more info on them?</p>

3

<p>It was in part B. </p>

<p>I believe the first part was:
Butane gets released out of water easily. Or something along those lines.</p>

<p>The second part was:
Butane has more no. of H bonds than water.</p>

<p>I wrote (T-T) I thought butance could be removed easily because it lacks H-bonding.</p>

4

<p>Oh, I think I remember.</p>

<p>I think it was like a solid butane can be removed out of liquid butane more easily than water out of water. And wasn’t the second part LESS H bonds than water? </p>

<p>I think I may have said T/T/CE or T/T. Can’t remember though.</p>

5

<p>I wrote in T-T
Nope, the second one is difnately ‘Butane has more H atoms than water’</p>

6

<p>What about some of the other questions?</p>

<p>What was the one that was like: “Which element has oxidation numbers +2 and + 3?”</p>

<p>I think i put Fe</p>

7

<p>If it was, then I definitely said T/T. I think that might be right, but it’ll depend on the viscosity values (possibly?).</p>

<p>Also said Fe.^</p>

8

<p>I put in Fe too.</p>

9

<p>Do radioactive elements have a surplus of electrons? (Part B)</p>

10

<p>I can’t find anything about the electrons in Barron’s/search with google. Not sure. I left it blank.</p>

<p>What was the question where it asked the element with the closest boiling point to 50degrees Celsius?</p>

11

<p>I put acetone or something like that, the leftmost curve.</p>

12

<p>I put in no. It would change atomic numbers then.</p>

13

<p>I put acetone as well.</p>

<p>What did you guys say for the part regarding the lab equipment at the beginning?</p>

14

<p>I put in acetone too.</p>

<p>I put in burette for both accurate delivery and titration.</p>

<p>Also, the Tru/false question about finding mass repeatedly to verify loss of water. Is it T-T CE?</p>

15

<p>I put the buret for two of those. I think the first and third questions? Did anyone else get that?</p>

<p>With the crucible? Yeah.</p>

16

<p>I put the buret and the graduated cylinder, and I doubled up on one of them. I don’t remember which. I know I did acid/base as buret, the first one about measurement as g.c., and I don’t remember about the water one.</p>

17

<p>for diluting with water its the round bottom flask thing.</p>

18

<p>Here we go:

19

<p>But a burette is more accurate. It has more divisions. And burettes are actually used for delivery. I dont see how that is wrong.</p>

20

<p>For which q?</p>
