math was a breeze, but chem - i did real bad : ( .

how much do you think I need on this thing to have a shot at the top ivies?

By Y17k (Y17k) on Saturday, October 09, 2004 - 05:05 am: Edit

i thought the chem was a lot easier than the practice tests on kaplans

BUT i did NOT know you couldnt use calculators in chem... it was a mild shock to find out that you couldnt use it..

By Yz16 (Yz16) on Saturday, October 09, 2004 - 07:21 am: Edit

oops sorry, when can we talk about the test?

By Sakrei (Sakrei) on Saturday, October 09, 2004 - 07:37 am: Edit

I am about to go take my tests, I hope chem isn't too bad.

how hard was the chemistry SAT II?!?! How was it as compared to the Barron's prep book?

By Perfectdark9 (Perfectdark9) on Saturday, October 09, 2004 - 09:32 am: Edit

I got a good score on Chem. If anyody has questions I'll be happy to answer them.

By Happybuddha2005 (Happybuddha2005) on Saturday, October 09, 2004 - 09:42 am: Edit

How difficult were the t/f questions?

By Perfectdark9 (Perfectdark9) on Saturday, October 09, 2004 - 10:09 am: Edit

They're not really that hard. If you have all your chemistry concepts in good form, you can easily ace the T/F Q's.

As a tip, try to determine first whether either of the statement is True or False, and then consider whether they are linked. You can easily rule out "CE" if you have at least one of them as False.

LETS post up chem answers from teh test!! are we allowed to yet?

By Piman3141 (Piman3141) on Saturday, October 09, 2004 - 12:04 pm: Edit

chem was a joke!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I completed AP Chem almost 5 months ago, didnt study at all between then and now, and Im confident i got an 800. If youve prepared, youll do great.

By Dumplings726 (Dumplings726) on Saturday, October 09, 2004 - 12:09 pm: Edit

was it just me or did the chem seem harder than normal, not that i've taken it before. i mean i found it odd that i was REALLY rushing towards the end. i know it's not cause i'm stupid cause i got a 790 on phys and 800 on math IIc but right now i'm considering canceling my score

i dunno...

how did everyone else do, just estimating cause i wanna get a sense of the curve or whether i just sucked...

By Dumplings726 (Dumplings726) on Saturday, October 09, 2004 - 12:11 pm: Edit

a joke?

By Piman3141 (Piman3141) on Saturday, October 09, 2004 - 12:15 pm: Edit

no, an exaggeration. But easy? Yes!

By Blee731 (Blee731) on Saturday, October 09, 2004 - 12:58 pm: Edit

Just wondering-What did you get on the AP Test Piman3141? I got a 4 and thought the AP Chem test was super easy I think the Chem was easy, but I could be wrong seeing as how I got a 4 on the AP exam!

By Piman3141 (Piman3141) on Saturday, October 09, 2004 - 01:05 pm: Edit

i got a 5, and I, contrary to all others in my class, felt that the AP test was easy.

By Davidrune (Davidrune) on Saturday, October 09, 2004 - 01:09 pm: Edit

yo...

What do you add first.. water or acid?

Secondly, which is the most accurate..

I put buret.

By Wheelmann421 (Wheelmann421) on Saturday, October 09, 2004 - 01:11 pm: Edit

What did you guys put for the question:

Which of the following statements is not part of the Kinetic Molecular Theory of Gases?

I put A) At any time, all the gas particles move as the same speed.

By Wheelmann421 (Wheelmann421) on Saturday, October 09, 2004 - 01:12 pm: Edit

You put ACID into water.

By Wheelmann421 (Wheelmann421) on Saturday, October 09, 2004 - 02:33 pm: Edit

answer plz anyone

If any of you want to discuss talk to me on AIM at BbOyFoiBLe

By Davidrune (Davidrune) on Saturday, October 09, 2004 - 04:29 pm: Edit

I got two, I think.

Or One.

By Sakrei (Sakrei) on Saturday, October 09, 2004 - 05:08 pm: Edit

I got 3

By Theapprentice (Theapprentice) on Saturday, October 09, 2004 - 05:21 pm: Edit

3 T/t/ce

How did you all do? I think i prolly got 750+.... i wanted an 800 but it seems unlikely now...
what was that one on part A about separating pigment like in ink?

do what u otta... add acid to watta

By Theapprentice (Theapprentice) on Saturday, October 09, 2004 - 05:22 pm: Edit

wheelman ur right

By Sakrei (Sakrei) on Saturday, October 09, 2004 - 07:04 pm: Edit

Paper Chromatography for ink.

By Sakrei (Sakrei) on Saturday, October 09, 2004 - 07:50 pm: Edit

I got 3 T/T/CE as well thea, I wonder what kind of curve we will have? The test seemed a little harder than usual, so maybe the curve will skyrocket! *prays*

By Pepperhead21 (Pepperhead21) on Saturday, October 09, 2004 - 08:04 pm: Edit

what about the most accurate measuring device for volume??

By Piman3141 (Piman3141) on Saturday, October 09, 2004 - 08:13 pm: Edit

i said erlenmeyer flask, since i know that a volumetric flask is the MOST accurate, and the two are similar in shape, etc..

By Sakrei (Sakrei) on Saturday, October 09, 2004 - 08:34 pm: Edit

its burret, i put grad cyl ><

By Blee731 (Blee731) on Saturday, October 09, 2004 - 09:09 pm: Edit

Could someone please post a raw to scaled scoring range for the SAT II: Chem from the Reals or practice books? My old Barron's doesn't have one and I'd like to get an idea of my scaled score for today's test.

By Sakrei (Sakrei) on Saturday, October 09, 2004 - 09:45 pm: Edit

Predicted scale?

By Npatrick6 (Npatrick6) on Saturday, October 09, 2004 - 10:00 pm: Edit

Are you sure it's buret? I put graduated cylinder. What a stupid mistake that was...

I think I may have gotten 4 or 5 wrong... would you say that's in 800 range?

By Feuler (Feuler) on Saturday, October 09, 2004 - 10:03 pm: Edit

What exactly was the question?

A grad. cylinder would be best for finding the volume of something, a buret would be best for pouring out a certain volume (which you already know) of something.

Can anyone confirm that we can be discussing the test at this time?

By Sakrei (Sakrei) on Saturday, October 09, 2004 - 10:06 pm: Edit

It said which of the following is the best to measure volume? I think I missed too many. I left about 3 blank, and prolly missed maybe 10+. I hope i can get 780+ with that...

By Npatrick6 (Npatrick6) on Saturday, October 09, 2004 - 10:14 pm: Edit

Yeah I think the question was "which is the most accurate device for measuring volume?" If you want to measure a total volume, then I'd say it's graduated cylinder... but if you wanted to measure a volume of one liquid out into another container (and just measure the volume of that liquid) then it would be a buret... tricky tricky...

By Npatrick6 (Npatrick6) on Saturday, October 09, 2004 - 10:21 pm: Edit

Oh yeah, what was the answer to the T/F T/F CE question about I2 and HI... the first question asked if I2's boiling point was higher than HI's boiling point (I think...) and the second question asked if the London dispersion forces among I2 were stronger than the ionic bonds of HI...

I think I said true, and false respectively.

I'm not sure if that was the exact question though... anyone remember for sure?

By Npatrick6 (Npatrick6) on Saturday, October 09, 2004 - 10:24 pm: Edit

Now that I think about it it was melting point instead of boiling point, sorry.

By Cb43087 (Cb43087) on Saturday, October 09, 2004 - 11:26 pm: Edit

I think i did pretty bad...taking chem after math and writing is like hitting a brick wall....

By Sakrei (Sakrei) on Saturday, October 09, 2004 - 11:56 pm: Edit

Amen to that Cb, but it was either that or 85 question test before math.

By Wheelmann421 (Wheelmann421) on Sunday, October 10, 2004 - 03:50 am: Edit

What did u put for the question stating: Which of the following staements are not part of the knetic molecular theory?

I put A. Gas particles at a given time do not move at the same speed

By Sakrei (Sakrei) on Sunday, October 10, 2004 - 09:55 am: Edit

Do you remember any other options ?

By Davidrune (Davidrune) on Sunday, October 10, 2004 - 10:23 am: Edit

The only one that could have been wrongwas the one that said that the space between gas particles was immense.

But that is also right. The rest were just standard definitions of the ideal gas laws.

By Sakrei (Sakrei) on Sunday, October 10, 2004 - 10:36 am: Edit

David did you take the test?

By Npatrick6 (Npatrick6) on Sunday, October 10, 2004 - 12:52 pm: Edit

Wheelmann I'm pretty sure you are right. Only the AVERAGE speed of the gas particles is taken into consideration. By no means are all the gas particles moving at exactly the same speed all the time.

By Theapprentice (Theapprentice) on Sunday, October 10, 2004 - 01:59 pm: Edit

I think the measuring device thingy is graduated cylinder
burets are reallly accurate, but u dont measure with them as much.. the answer is graduated cylinder. I took this in june and yesterday... i was like whoohoo cuz i asked my chem teacher after i took it last year and she told me that.

I put that KI had a higher boiling pt... ionic solids have really high boiling pts rite? Especially compared to a stupid covalent bond... london dispersion forces are weak compared to ionic.

The answer on the gas one about particles was A... not all move at the same speed... thats stupid.

And i agree with Cb93893 or w/e about the brick wall.. i took chem after math and i was pumped cuz i felt i had just got an 800.. then chem killed my mood.

According to Kaplan, out of 85, u havta get 78 for an 800 (thats your raw... with the .25 pts dedcuted).. ReAL sat2 says its about 2 less than that... I really think that the curve will be nice here. I felt that they did not follow what they said about what topics appear the most... i felt that like half the test was on like molarity and kinetic molecular theory.. Last time it was about easy stuff like atomic structure (wat it should be... 25%)

Are you sure about paper chromatography? Im in denial....
nvm i just checked ur right
how did you guys know that?

By Wheelmann421 (Wheelmann421) on Sunday, October 10, 2004 - 02:13 pm: Edit

apprentice thanks for answering like four questions. yur post was really helpful to me and cleared some questions I had doubts about.

I also put paper chromatography because I did this experiment at school.

I have 2 questions:

The multiple choice question with the solubilities of 2 substances at 20, 40, and 60 degrees Celcius. It asked what could be concluded from the following.

What is the pH of KCl?
I put 7 because it is a salt of a really strong base and acid. (strong base: KOH srong acid: HCL)

Please post back with your answers.

By Davidrune (Davidrune) on Sunday, October 10, 2004 - 02:33 pm: Edit

- The thing showed us that one was exothermic and the other was endothermic.

- The solubility was 7.

By Sakrei (Sakrei) on Sunday, October 10, 2004 - 03:19 pm: Edit

Does anyone remember the question that was:

Cl2 + Br- -> 2Cl- + Br2

Add .1M cl-?(I dont rememebr which ion was added, or diatomic molecule for that matter) to the reaction. How much Br-? came out?

By Wheelmann421 (Wheelmann421) on Sunday, October 10, 2004 - 03:29 pm: Edit

sakrei i think da above equation is wrong cuz Cl2 is getting reduced but nothing is getting oxidized

By Sakrei (Sakrei) on Sunday, October 10, 2004 - 03:33 pm: Edit

Whatever do you mean?

By Davidrune (Davidrune) on Sunday, October 10, 2004 - 03:57 pm: Edit

[EDIT]

By Davidrune (Davidrune) on Sunday, October 10, 2004 - 03:57 pm: Edit

There is nothing wrong with the reaction above.

Cl2 is getting reduced and Br- is getting oxidized.

But I dont remember a question like that.

By Davidrune (Davidrune) on Sunday, October 10, 2004 - 03:58 pm: Edit

By Npatrick6 (Npatrick6) on Sunday, October 10, 2004 - 04:04 pm: Edit

Paper chromotography was definitely the answer to the question about identifying inks or whatever... I've done at least 2 paper chromotography labs in school and that was definitely one of the answers in the matching section.

0.1M KCl has a pH of 7 because yeah, it is just a salt.
0.1M NH3 has a pH of between 8 and 13 because it is a weak base.
0.1M HC2H3O2 (acetic acid) has a pH of between 2 and 6 because it is a weak acid.

I remember the Br and Cl question but I forget what it was exactly, so I forget the answer.

By Davidrune (Davidrune) on Sunday, October 10, 2004 - 04:06 pm: Edit

Oh those bitches... they re-wrote acetic acid in such a way that you can't figure out what it is.

Whateve... I got the question right. But damn...

By Npatrick6 (Npatrick6) on Sunday, October 10, 2004 - 04:15 pm: Edit

Actually the equation would have to be:

Cl2 + 2Br- -> 2Cl- + Br2


Cl is being reduced and Br is being oxidized.

By Davidrune (Davidrune) on Sunday, October 10, 2004 - 04:25 pm: Edit

The only difference between your equation and his is that he forgot to balance his equation.

By Npatrick6 (Npatrick6) on Sunday, October 10, 2004 - 05:20 pm: Edit

Hahaha... ummm, yeah, I think I noticed that. Thanks.

By Sakrei (Sakrei) on Sunday, October 10, 2004 - 05:21 pm: Edit

So do you remember the answer?

By Npatrick6 (Npatrick6) on Sunday, October 10, 2004 - 05:25 pm: Edit

I'm not sure what the exact question was.

Was this the third or fourth question in the multiple choice section? Because I remember getting an answer of .025 around there somewhere. Honestly though, I don't even know if I'm thinking of the right question.

By Sakrei (Sakrei) on Sunday, October 10, 2004 - 05:41 pm: Edit

.025 was an answer in the beginning of mult choice i remember. Later on the test was this question. I am really hoping for a nice curve on this test. I think i may have gotten a raw score somewhere aroudn 70 :/.

By Wheelmann421 (Wheelmann421) on Sunday, October 10, 2004 - 06:25 pm: Edit

Do you guys remember that roman numeral question in which it asked the products of the reaction between two compounds? All I remember was that roman numeral 2 was Carbon Dioxide (CO2)

By Davidrune (Davidrune) on Sunday, October 10, 2004 - 07:49 pm: Edit

yea... I vaguely remember that question. I think the answer was Carbon Dioxide. The other ones were not in the right quantity.

0.025 is a familar answer.

By Wheelmann421 (Wheelmann421) on Sunday, October 10, 2004 - 08:02 pm: Edit

On that T/F question,

1) You should pour water into acid.
2) Solutions heat up when acid is added

What did u put for the second statement? I put False

By Piman3141 (Piman3141) on Sunday, October 10, 2004 - 08:16 pm: Edit

it is false. Or it better be, because thats what i put.

By Davidrune (Davidrune) on Sunday, October 10, 2004 - 08:54 pm: Edit

It didn't say solutions heat up...

It said WATER HEATS UP...

And that is clearly true. Have you ever mixed water and hydrochloric acid? The beaker is noticeably hotter...

Even if you just think of it from an intermolecular standpoint. dissolving produces heat.

By Wheelmann421 (Wheelmann421) on Sunday, October 10, 2004 - 09:54 pm: Edit

Not necessarily david

a cold pack is a solution of two chemicals that absorb heat and thus is COLD

By Npatrick6 (Npatrick6) on Sunday, October 10, 2004 - 10:35 pm: Edit

http://antoine.frostburg.edu/chem/senese/101/safety/faq/always-add-acid.shtml

"A large amount of heat is released when strong acids are mixed with water. Adding more acid releases more heat."

By Davidrune (Davidrune) on Sunday, October 10, 2004 - 10:58 pm: Edit

The question isn't asking about solutions and acids. It's asking specifically about WATER AND ACIDS.

And as Npatrick6 just pointed out, this reaction releases heat.

By Wheelmann421 (Wheelmann421) on Monday, October 11, 2004 - 12:33 am: Edit

dang I guess I was wrong.

I have two more questions:

What is the the stongest oxidizing agent? I put gold (Au)

Which of the following are good solid electric conductors? I put it Na, Fe, and Au

By Davidrune (Davidrune) on Monday, October 11, 2004 - 12:39 am: Edit

The second is right.

I think the first was Ca or something.

By Al0 (Al0) on Monday, October 11, 2004 - 01:26 am: Edit

The strongest oxidizing agent is the only one that can be reduced (I believe there was only one and that it was Cl2). Also, I thought the second one was Na, Cu and Au, but it was definitely three metals.

By Feuler (Feuler) on Monday, October 11, 2004 - 02:53 am: Edit

Yes- any time you are given four answer choices, one of which is unlike all the others in some notable way (in this case, one was a non-metal, all the others were metals), it's a pretty good bet that the correct answer is the one that is not like the others.

Just a helpful hint I've picked up from taking too damn many standardized tests...

By Wheelmann421 (Wheelmann421) on Monday, October 11, 2004 - 07:49 pm: Edit

Cl2 is a molecule and therefore would not reduce anything. In addition, if you looked at an electromotive series, Au is like the lowest element, making it the stringest oxidzing agent because it wants to get reduced.
