How did you think it was? Good? Bad?
Predicted/Desired score?
Just initial emotional responses until 5/2 at noon though!

I thought it was not bad, maybe a little long. Worried about bubbling mistakes. Probably 750 to 800, somewhere in there....but hoping for that magic number, 800, though!

I got 7 t/t/ce. few too many i think. 5 of them i was sure of, 2 were guesses. anyone remember any of them? im having a brain block at the moment. is H2+O2 endothermic? I thought it was exo. And isnt O2 more reactive than N2?

By Daromanian (Daromanian) on Saturday, May 01, 2004 - 12:07 pm: Edit

kewlkiwi...
h2 + o2 is HIGHLY exothermic. that one was F,T
O2 is more reactive than N2 becuz N2 has a stronger bond (triple)
i hope lol.

By Kms0484 (Kms0484) on Saturday, May 01, 2004 - 12:09 pm: Edit

so the o2 and N2 question is false? or true? i forgot..

yay! thanks daromanian. im happy now. werent a lot of the I, II, III style questions all of the above? What about the metallic property one?

By Kewlkiwi102 (Kewlkiwi102) on Saturday, May 01, 2004 - 12:10 pm: Edit

nh3 is polar

By Kms0484 (Kms0484) on Saturday, May 01, 2004 - 12:10 pm: Edit

NH3...isn't it? i thought NH3 was definitely the answer

By Daromanian (Daromanian) on Saturday, May 01, 2004 - 12:12 pm: Edit

metallic was all 3, take in heat well, conduct electricity, are lustrous.
:D

and yes nh3 is polar

By Kms0484 (Kms0484) on Saturday, May 01, 2004 - 12:12 pm: Edit

yea kewlkiwi, I think I chose every question like I,II,III almost e...

By Kewlkiwi102 (Kewlkiwi102) on Saturday, May 01, 2004 - 12:13 pm: Edit

yep,NH3 is trigonal pyrimidal andhas a lone pair, so it is polar :D

By Qwert271 (Qwert271) on Saturday, May 01, 2004 - 12:13 pm: Edit

I hope thats what I put.

By Daromanian (Daromanian) on Saturday, May 01, 2004 - 12:14 pm: Edit

O2 --> 2O
I) endothermic
II) increases entropy
III) can be done by UV

I,II,III nebody?

what was the one with number of hydrogen atoms in the hydrocarbon towards the end.
with .1 mole hydrocarbon producing .4 mole h20 .
i put 8

By Bhaiyu87 (Bhaiyu87) on Saturday, May 01, 2004 - 12:16 pm: Edit

i put all 3 daromanian
im, sure about I and II, not sure about 3 tho.
but i figured UV contains energy, which might make the O2 turn into 2O.

By Daromanian (Daromanian) on Saturday, May 01, 2004 - 12:19 pm: Edit

8 is right bhaiyu97.
it was
CxHy + O2(irrelevant) --> CO2(irrelevant)+ (1/2y)H2O

1/2y = 4
y = 8
:D

never seen a question like that ever before, the concept was a bit tough to pick up on i thought.

which of the gases was the best oxidizing agent?

By Cherrybarry (Cherrybarry) on Saturday, May 01, 2004 - 01:37 pm: Edit

F2.

What about problem about the volume needed to be added to 15.0M to make 1.0 L 3.0M? I think you needed 200 mL for mole equivalence but then add 800 mL water to make the the solution? Was it asking amount of water needed to be added or amount of the 15.0M solution?

By Yermama (Yermama) on Saturday, May 01, 2004 - 01:39 pm: Edit

i believe it was 500 mL

x/15 = 1/3
x=5 L --> 500 mL

not positive, i was rushing really really fast...

and why was it F2?

anyone have any insights into the question about "which of the following will be a product"
I. NH3
II. BaCl2
III. H2O

I thought it was BaCl2 only, but some ppl think it is all three. any ideas? I thought that in solution NH3 did not exist, it was NH4OH. And why would H2O be a product? Wouldnt it be OH-?

By Kms0484 (Kms0484) on Saturday, May 01, 2004 - 02:00 pm: Edit

so..wait, is K is the the best conductor of electricity? not Si?

By Yermama (Yermama) on Saturday, May 01, 2004 - 02:04 pm: Edit

it was all 3 for the products. NH4OH --> NH3 + H20

By Kms0484 (Kms0484) on Saturday, May 01, 2004 - 02:05 pm: Edit

yep kewlkivi, I only put BaCl2, others don't form, Im pretty sure, BaCl2 and NH4OH

By Kewlkiwi102 (Kewlkiwi102) on Saturday, May 01, 2004 - 02:06 pm: Edit

Are you sure that NH3 can exist in solution? I thought that i read that it couldnt, that it was always NH4OH....

By Kms0484 (Kms0484) on Saturday, May 01, 2004 - 02:13 pm: Edit

damn my b, yermama is right damnit!

By Kewlkiwi102 (Kewlkiwi102) on Saturday, May 01, 2004 - 02:15 pm: Edit

Kms, are you sure they are right about the BaCl2 one? hmm...im sad now...

By Cherrybarry (Cherrybarry) on Saturday, May 01, 2004 - 02:29 pm: Edit

yes NH3 can exist in solution. NH4OH as a compound cannot exist in solution. It dissolves completely. The rxn was a ppt rxn and a neutralization between NH4+ and OH- which yields NH3 and H20.

NH3 is a weak base and very little disassociates into NH4. Kb for NH3 is only like 1.5x10^-5.

By Kewlkiwi102 (Kewlkiwi102) on Saturday, May 01, 2004 - 02:29 pm: Edit

anyone have anything else to say about the NH3 one and the Si one?

By Kewlkiwi102 (Kewlkiwi102) on Saturday, May 01, 2004 - 02:39 pm: Edit

Wait what about the TFCE one that was about the states of H and He and whether or not elements in the same row were ususally in the same state? I think it was

H and He are both gasses at room temperature
becuase
Elements in the same period tend to be in the same state under the same conditions

I think I said TTCE. Now I am kicking myself . It was TF wasnt it?

By Kms0484 (Kms0484) on Saturday, May 01, 2004 - 02:42 pm: Edit

hmm? I thought it had nothing to do with period...so, i chose TF -_-; well; and second?

By Silmon77 (Silmon77) on Saturday, May 01, 2004 - 02:52 pm: Edit

Think about it...Kr is a gas, but is in the same period as the transition metals, which are solids, so H and He would be TF.

By Skapoor1 (Skapoor1) on Saturday, May 01, 2004 - 02:54 pm: Edit

what was the first question,about surface tension of water? I put T T CE

By Kewlkiwi102 (Kewlkiwi102) on Saturday, May 01, 2004 - 02:55 pm: Edit

Ah, but it says "tend to be," not "always are." and if you look at the table, they do tend to be mostly the same. I saw a question that was nitpicky like that somewhere, 22 reals? barrons? something like that. thats why I'm not sure

By Asfafan (Asfafan) on Saturday, May 01, 2004 - 02:56 pm: Edit

i only had 4 CE's!

By Skapoor1 (Skapoor1) on Saturday, May 01, 2004 - 03:48 pm: Edit

About "tend to be", I'm fairly sure that one is incorrect. If rows tended to be of the same state, you would be able to make generalizations like " row 3 tends to be metallic", however that is unheard of and sounds wrong. It might be right, but i would put my money against it.

Wow, this is real cool.

Looking over all these posts, I'm feeling a bit better.

I was really pressed for time- skipped 10.

Probably 12 wrong- which I guess is like a 680-700.

There was one question for redox, where u had to do the whole balancing of the redox equation, then it asked for a coefficient. I got three. Anyone else?

By Scion (Scion) on Saturday, May 01, 2004 - 06:03 pm: Edit

jay-uh, asfafan, i had 4 CEs too! or maybe 5, i forgot now

also, did anyone get T/T for the first 2 of the T/T/CE questions?

and, were there 1.2 X 10^24 (?) oxygen atoms (choice E)?

can someone clear this question up? (what was the question anyway?)
"which of the following will be a product"
I. NH3
II. BaCl2
III. H2O
i got I and III???

was iodine the purple vapor?

did zinc in hydrochloric acid disappear and turn into a gas?

anymore guys?

By Aab123 (Aab123) on Saturday, May 01, 2004 - 06:06 pm: Edit

Scion-

All three were the products
The first two were T/T/CE, i got 4 or 5 CE's
Iodine is the purple vapor
I said choice A for the oxygen atoms

By Aab123 (Aab123) on Saturday, May 01, 2004 - 06:09 pm: Edit

Did anyone get like three C's in a row in the second column?

By Scion (Scion) on Saturday, May 01, 2004 - 06:13 pm: Edit

aab123, for the products one, what exactly was the question again?

and can u explain choice A for the oxygen atoms?

and y were the first two T/T/CE? what was the question again? can anyone second this?

also did u happen to get A LOTTA D's around nubmers 27-32?

By Scion (Scion) on Saturday, May 01, 2004 - 06:15 pm: Edit

o yeah, did the system reach equilibrium at V? i hope...

By Aab123 (Aab123) on Saturday, May 01, 2004 - 06:18 pm: Edit

Scion- don't remember exactly, but due to the number of moles of the polyatomic ions, it made sense to me that all three were produced ( i think it says this earlier in the thread as well)

The first T/F was that water has a high surface tension, which is true. Because of hydrogen bonds, also true. so CE

I don't remember the second one, but I do remember getting a lot of D's.

Also, is the Princeton Review scale accurate, or the Barrons ( I hope, hehe)

By Aab123 (Aab123) on Saturday, May 01, 2004 - 06:19 pm: Edit

Yes, it reached equilibrium at V, and the largest change was between I and II

By Scion (Scion) on Saturday, May 01, 2004 - 06:29 pm: Edit

o aab123, what was the one about what was NOT conserved? i put mass...

O YEAH, at least i got the equilibrium one right! o yeah (sorry-i have to celebrate)

By Aab123 (Aab123) on Saturday, May 01, 2004 - 06:31 pm: Edit

I said molecules...gimme ur sn maybe we can talk online. Mine is aabizgod

By Kewlkiwi102 (Kewlkiwi102) on Saturday, May 01, 2004 - 06:32 pm: Edit

mass is ALWAYS conserved. theres a law. number of MOLECULES wasnt.
I got 1.2x10^24 for the oxygen one I think.
Should be about 5 CEs.

By Kewlkiwi102 (Kewlkiwi102) on Saturday, May 01, 2004 - 06:34 pm: Edit

Btw, what were those scales like? I know in 22 reals it was 6 wrong for an 800.
Did anyone think this was substantially harder than 22 reals?

By Aab123 (Aab123) on Saturday, May 01, 2004 - 06:35 pm: Edit

Yes! Thank you Kewlkiwi- I got the conservation right, plus the T/F. Not the second one tho. O well.

By Kewlkiwi102 (Kewlkiwi102) on Saturday, May 01, 2004 - 06:36 pm: Edit

which T/F? the He and H one? Cause i talked to my grandfather (works in a field of chem) and he said he would have put TTCE for that one.

By Aab123 (Aab123) on Saturday, May 01, 2004 - 06:37 pm: Edit

Kewlkiwi- 6 wrong? Or do you mean 6 off of the raw score of 85...

By Kewlkiwi102 (Kewlkiwi102) on Saturday, May 01, 2004 - 06:38 pm: Edit

Hmm...I cant remember. I think 6 wrong. Becuase 78 raw is an 800, so 77.5 would round up to 78. so yeah, 6 wrong.

By Aab123 (Aab123) on Saturday, May 01, 2004 - 06:38 pm: Edit

Well for the He and H: that was worded weirdly, as was put before. HOWEVER, when it says TENDS, it means one or two exceptions. However, if you go horizontally, u do change... I dunno it was weird.

By Smiliekat (Smiliekat) on Saturday, May 01, 2004 - 06:40 pm: Edit

i skipped 2. how many wrong to still get a 800? 770?
i know i missed at least 2 or 3.

By Smiliekat (Smiliekat) on Saturday, May 01, 2004 - 06:41 pm: Edit

for the redox...was it not 6 H+'s?

By Aab123 (Aab123) on Saturday, May 01, 2004 - 06:46 pm: Edit

Sorry, I DID get that Smilikat. I think I said otherwise earlier in the thread.

Also, if you skipped 2, and got like 1 or 2 other wrong, you definately got an 800.

By Smiliekat (Smiliekat) on Saturday, May 01, 2004 - 06:55 pm: Edit

thanks man.
wow...i just realized that...due to my rush on the chem test...i somehow came up with "bonds breaking = exothermic" how stupid is that...
oh well. so thats the two i definitely missed.
dude sat iis are so much harder than aps cuz you cant miss as much and still get a perfect score.

By Aab123 (Aab123) on Saturday, May 01, 2004 - 06:57 pm: Edit

But the curve on Chem is pretty big, from what I hear. Plus, it's only a fourth of a point off for an incorrect answer.

By Neumeisterwd (Neumeisterwd) on Saturday, May 01, 2004 - 07:29 pm: Edit

How many could i get wrong and get a 600?

By Mehere (Mehere) on Saturday, May 01, 2004 - 08:37 pm: Edit

usually 5 - 6 wrongs, but depends on difficulty of test.

By Smadans (Smadans) on Saturday, May 01, 2004 - 08:43 pm: Edit

At 25 C, does CH4, C2H6, F2 or Ne move faster

By Neumeisterwd (Neumeisterwd) on Saturday, May 01, 2004 - 09:16 pm: Edit

Thats all!!! I thought the curve was bigger. In my test book it says i could get around 42 right (raw score) and get a 600. Anyways, I put that Ch4 moves fastest because it has the lowest molar mass. Did anyone else find the questions at the beginning the hardest? To me, it is hardest to remember the properties of certain bases and acids. Also, what did anyone put for the voltage question?

By Daromanian (Daromanian) on Saturday, May 01, 2004 - 09:17 pm: Edit

CH4 -- the lightest
KE = .5MV^2, therefore the V has to make up for the small M

Does anyone know what a good score is? (I dont mean 800, i mean a solid score for a UC).

By Daromanian (Daromanian) on Saturday, May 01, 2004 - 09:22 pm: Edit

750+ because the curve is lenient.

By Scion (Scion) on Saturday, May 01, 2004 - 09:34 pm: Edit

ooo, was the second of the T/T/CE questions about the hydrogen and the helium??? cuz if it was then i put T/F. o wait, maybe that isnt the second one. and about the curve, in real sat 2s, the curve IS pretty lenient!!! yay for us!

By Sarasote (Sarasote) on Saturday, May 01, 2004 - 09:46 pm: Edit

How many could i get wrong and get a 600?
in past tests it was usually 78 out of 85 points is an 800 and you can figure your thing from there.

Does anyone know what a good score is? (I dont mean 800, i mean a solid score for a UC).
Ivies prefer 700+ so look at ur score from there

The first ce section was not at T/T/CE, it was only T,T.

and y were the first two T/T/CE? what was the question again? can anyone second this?
the first one was not T/T/CE but the second one was. there were 5 T/T/CEs. Water does not have high surface tension because of hydrogen bonds (that is where biology comes in). Though hydrogen bonds is one of the strongest intermolecular forces, it does not account for the surface tension

By Scion (Scion) on Saturday, May 01, 2004 - 09:49 pm: Edit

"The first ce section was not at T/T/CE, it was only T,T."

THANKS SARASOTE.

but i still got the second one wrong anyway, BUT at least the first one was right. i hope

By Daromanian (Daromanian) on Saturday, May 01, 2004 - 10:11 pm: Edit

1. water has high surface tension, water has hydrogen bonds

T T ce

By Daromanian (Daromanian) on Saturday, May 01, 2004 - 10:12 pm: Edit

the hydrogen bonds is why the water holds together (surface tension = molecules pulling in on each other rather than dispersing)

By Mehere (Mehere) on Saturday, May 01, 2004 - 10:13 pm: Edit

yes i got ttce for first two.

By Kms0484 (Kms0484) on Saturday, May 01, 2004 - 10:15 pm: Edit

same here TTCE. what about the question # 2?

By Sarasote (Sarasote) on Saturday, May 01, 2004 - 10:20 pm: Edit

question 2 was definitely TTCE. i dont remember the question tho.

at a constant pressure and temperature 12g of oxygen occupies 20 L. what is the molar mass of a gas that occupies 10 L.

WHAT THE HECK??

i literally almost fainted trying to figure this out, im sure its really easy but its one of the few that just plain hurt my brain, i started getting light headed and couldnt read so i skipped it, went back and guessed B

By Kewlkiwi102 (Kewlkiwi102) on Saturday, May 01, 2004 - 11:31 pm: Edit

its gotta have 2x the molar mass of oxygen becuase you have the same mass of it but it takes up half the volume. so it was 64.

By Speeddemon608 (Speeddemon608) on Sunday, May 02, 2004 - 12:16 am: Edit

got that wrong, i think i mightve kept reading the question wrong, dont know what was going on in my head...arggg 1 more uneccesarily wrong

By Kewlkiwi102 (Kewlkiwi102) on Sunday, May 02, 2004 - 08:54 am: Edit

Hey what about the one that was like, which of the following is not and observation? I put that the solution contains silver ions- you cant see that you would have to test for it or just assume it, but i am not sure.

By Aab123 (Aab123) on Sunday, May 02, 2004 - 09:37 am: Edit

I also said that you cannot observe silver ions, and I also got 64 as the Mass. You need to look at the ratio.

By Silmon77 (Silmon77) on Sunday, May 02, 2004 - 03:23 pm: Edit

From Zumdahl Chemistry Textbook:
"As we would expect, liquids with relatively large intermolecular forces, such as those of polar molecules, tend to have relatively high surface tensions."

Which means that the 1st(im assuming) T/F is T T CE, because hydrogen bonds between water molecules produce large intermolecular forces, causing greater surface tension.

lets keep this discussion going.

By Needhelp06 (Needhelp06) on Sunday, May 02, 2004 - 04:18 pm: Edit

What questions did people find the hardest that weren't in the T/F section? I'm talking about the first twenty-some problems and ones after the true /false section?

By Scion (Scion) on Sunday, May 02, 2004 - 04:36 pm: Edit

hey, u know in the real sat 2s book, the curve for chem is REALLY nice... i hope it is too for this one...

By Kewlkiwi102 (Kewlkiwi102) on Sunday, May 02, 2004 - 04:45 pm: Edit

did you guys think this was harder than the one in the book? now that i reflect on the test i do think so.

By Binarystar (Binarystar) on Sunday, May 02, 2004 - 05:25 pm: Edit

What was the weak base in the first or second question??

By Kewlkiwi102 (Kewlkiwi102) on Sunday, May 02, 2004 - 05:54 pm: Edit

NH3

By Needhelp06 (Needhelp06) on Sunday, May 02, 2004 - 06:24 pm: Edit

what else did you guys find relatively difficult in the first few problems? how close was this test to the one in the 22 real sat's in terms of the type of problems asked in the section before the true/false section? Were the type of problems the same (eg atomic periodicity, then analyzing graphs, etc)? Thanks a lot!

By Needhelp06 (Needhelp06) on Sunday, May 02, 2004 - 08:42 pm: Edit

which were the hardest multiple choice questions in your guy's opinion?? please answer...dying to find out if I got the right answers

By Scion (Scion) on Sunday, May 02, 2004 - 08:44 pm: Edit

hey does anyone remember the electrochemistry question? it was like, if it takes a certain number of moles to convert Cu 2+, then how many would it take to convert Ag (?) + ? i think that i put half the number of moles, cuz its Ag +, and the moles was given for Cu 2+. sorry this is so confusing, but does anyone remember?

By Kewlkiwi102 (Kewlkiwi102) on Sunday, May 02, 2004 - 09:04 pm: Edit

no i thought that it was if you have enough moles of electrons to convert 1 mole of Cu+2. how many moles of Ag+ could you convert. it would be 2 moles of Ag+.

By Binarystar (Binarystar) on Sunday, May 02, 2004 - 09:13 pm: Edit

What did you guys get for the voltage question? I didn't learn anything about it so I just guessed :S

By Kewlkiwi102 (Kewlkiwi102) on Sunday, May 02, 2004 - 09:26 pm: Edit

the 0.93 one?

By Scion (Scion) on Sunday, May 02, 2004 - 09:40 pm: Edit

yeah kewlkiwi102, i agree. but i dont exactly remember the question :P but i hope i put the right answer anyway. and for the voltage one, do u remember the question exactly?

By Needhelp06 (Needhelp06) on Sunday, May 02, 2004 - 09:52 pm: Edit

for the problem where it asks if sodium burns yellow, did you guys get (T,T) or (T,T, CE)?? Please answer.

By Kewlkiwi102 (Kewlkiwi102) on Sunday, May 02, 2004 - 09:55 pm: Edit

oooh...no it had lots of information in it...gosh. (i think if you looked at some info they gave you and understood it you could actually reason your way through how to gdo it with out much knowldge of electro.) i think it asked for the standard potential of the reactio n cell between Ag and Cu maybe, and have given you the standard reduction potentials of each...and then asked you to find it. you have to negate one of them and then add them together. pretty simple standard reduction potential question if i remember correctly.

By Kewlkiwi102 (Kewlkiwi102) on Sunday, May 02, 2004 - 09:56 pm: Edit

wasnt the sodium question a normal mc question?

By Neumeisterwd (Neumeisterwd) on Sunday, May 02, 2004 - 10:25 pm: Edit

for the voltage one, did you just do what the example did

By Kewlkiwi102 (Kewlkiwi102) on Sunday, May 02, 2004 - 10:28 pm: Edit

Pretty much! Im not entirely sure why they even gave that example....
can anyone check me on the sodium question? i am positive, er almost positive, that it wasnt a t/f/ce, it was an MC near the middle of the end (oh like that makes a lot of sense...the middle of the end...)

By Daromanian (Daromanian) on Sunday, May 02, 2004 - 10:43 pm: Edit

ooh one T/T/CE was aboot acid rain.
2) acid rain lowers ph of lakes, acid rain increases hydronium ion concentration of lakes

was that t/t/ce?

By Aab123 (Aab123) on Sunday, May 02, 2004 - 10:44 pm: Edit

The Electrochemistry one was 1.47

By Daromanian (Daromanian) on Sunday, May 02, 2004 - 10:49 pm: Edit

how do you figure 1.47?
it was .9 and .17 or something of the sort, anyway the only positive combo that was present was closer to 1 i think

By Kewlkiwi102 (Kewlkiwi102) on Sunday, May 02, 2004 - 10:51 pm: Edit

no. the electro one was 0.93.

By Daromanian (Daromanian) on Sunday, May 02, 2004 - 10:53 pm: Edit

what were the 2 potentials?
.8
and -.13?
something like that?

By Kewlkiwi102 (Kewlkiwi102) on Sunday, May 02, 2004 - 10:55 pm: Edit

yep those sound about right. and you had to negate the -0.13 becuase the reaction for that one needed to go the other way from the way it was given. so 0.93. (jeez, how is it that we remember all of these random values but I can never memorize constants? Oo)

By Binarystar (Binarystar) on Sunday, May 02, 2004 - 11:13 pm: Edit

Ahh, okay so I guessed right. I just followed the example ^_^.

By Needhelp06 (Needhelp06) on Sunday, May 02, 2004 - 11:18 pm: Edit

so what did you guys put for the sodium burning question?

By Binarystar (Binarystar) on Sunday, May 02, 2004 - 11:27 pm: Edit

I remember the sodium burning question was a normal question, and I remember something about it burning yellow. Not really sure what the question or the answer choices were.

By Needhelp06 (Needhelp06) on Sunday, May 02, 2004 - 11:33 pm: Edit

what were the hardest multiple choice questions, or at least the multiple choice questions you remember?

By Binarystar (Binarystar) on Sunday, May 02, 2004 - 11:36 pm: Edit

The only ones I didn't know for sure were the one about the weak base (stupid, I know... I just totally had a brainfart) and the one where you were given a graph to interpret and figure out where the substance condensed.

By Aab123 (Aab123) on Sunday, May 02, 2004 - 11:38 pm: Edit

Yea, does anyone remember the first four questions?

By Binarystar (Binarystar) on Sunday, May 02, 2004 - 11:41 pm: Edit

One of them was asking for the weak base, the other one was asking for the acidic one, and that's all I can remember.

By Binarystar (Binarystar) on Sunday, May 02, 2004 - 11:48 pm: Edit

By the way, is it possible to get a F - T - CE ? The directions seemed to say CE only applied when the first two were true, so I thought no.

By Needhelp06 (Needhelp06) on Sunday, May 02, 2004 - 11:52 pm: Edit

the answer to the weak base was NH3, but what was the acidic one? anyone remember?

By Binarystar (Binarystar) on Sunday, May 02, 2004 - 11:53 pm: Edit

Do you recall any of the answer choices?

By Needhelp06 (Needhelp06) on Monday, May 03, 2004 - 12:06 am: Edit

no, can anyone else remember what the answer to the multiple choice acid question was in the beginning of the test? what other multiple choice questions do you guys remember?

By Silmon77 (Silmon77) on Monday, May 03, 2004 - 01:11 am: Edit

Out of curiosity, what was the answer to the question where you were given the m/b pts and densities of two substances, and you had to figure out how to seperate them? I narrowed the choices down to filtration and distillation, but I left it blank.

By Sarasote (Sarasote) on Monday, May 03, 2004 - 01:14 am: Edit

distillation

this is when you have two closed flasks connected by a tube and u boil the liquid to separate them. since they had greatly differing boiling points, you would use distillation to boil one to gas and have it travel to the other flask and condense

By Aab123 (Aab123) on Monday, May 03, 2004 - 06:57 am: Edit

In order to get CE, the first two must be T

for the question about the decomposition of KCl03 into KCL and O2, and given 6 mols of KClO3, did you guys find that 9 mols of O2 were produced?

By Mehere (Mehere) on Monday, May 03, 2004 - 12:21 pm: Edit

How aabout the one they asked for color (blue i think). i think the choices were lithium, sodium and two heavy alkaine earth along with cu

By Daromanian (Daromanian) on Monday, May 03, 2004 - 05:39 pm: Edit

yes the ratio is 3/2.
so 6*3/2 = 9.

By Needhelp06 (Needhelp06) on Monday, May 03, 2004 - 07:56 pm: Edit

for one of the T/F/CE questions it asked if the bonds in NH3 were stronger than in PH3 because N was more electronegative than P. I think I put CE. was i right?

By Yermama (Yermama) on Monday, May 03, 2004 - 08:07 pm: Edit

ya i said because of H-bonding.

By Aab123 (Aab123) on Monday, May 03, 2004 - 08:08 pm: Edit

ye thats what i said.

By Needhelp06 (Needhelp06) on Tuesday, May 04, 2004 - 12:18 am: Edit

so was the answer CE then?

By Aab123 (Aab123) on Tuesday, May 04, 2004 - 02:12 pm: Edit

i think

By Mehere (Mehere) on Tuesday, May 04, 2004 - 02:54 pm: Edit

do u guys remember a question in the 30s about some color thing regarding metals and the choices were li, na, ba, and another heavey alkaline earth, and cu.

wut about the other one regarding color sulution wen a metal reacts in a solution (fprgpt exact qustion) but choices were like gree but ppt and stuff.., do u guys remember?

thx

for the one question about the bunsen burner flame being blue, was the right answer that the tip of the inner blue cone is the hottest part? Im pretty confident that I was right, anyone put something else?
