After looking at that chemistry regents im thinking i mustve cheated! 😱
but honestly, i didnt cheat until the SATs (Scholastic Acheivement Test). thats the test used to get into american colleges. too bad i didnt know each test was different!
Stuyvesant!! If X = Y then let X = Stuy and Y = No Life.
ahaha! What college did you get accepted to? Or still attending?
I go to Manhattan Hunter Science High School. I couldn't cheat in the Chemistry regents, because I had dumb kids around me. I was so effin' scared when I took it. Once I saw my results, I jumped around for about good five minutes. LOL!
I did cheat in the SATs!! Well, I copied two multiple choice from this girl but later on, I found out that the person next to you is taking a different section of the test. Whatever. I still got a 1750.

I know. There is one carbon next to each oxygen. If it was CO (s), then it would be 4. But it's gas.
i think you mean since it's CO (g), the answer is (4). (you explained correctly the first time)
if it was (s), then the answer would have been (3). 🙂

I am shocked I actually understood some of them questions.. (Doing chemistry in school at the moment I am like failing 😛).
i prefer the old-fashion way - just have someone that sorta looks like you take the exam! 😀
you may laugh now, but it does happen in college.
I do have a TI-83 thats permitted and they don't ask you to clear them for science tests.

Hunter is a prestigious school in manhattan. i actually remember taking a test in 2nd grade to get in, but i think i didnt score well enough.
after stuy, i went to college of william and mary, 2nd oldest school in usa. jon stewart and glenn close are some famous alumni. do you have your sights on a school yet? with an SAT score like yours i bet you could get into virtually anyone of them. my sister goes to columbia now, and she loves it. only thing now is she wants to move out but she knows the parental units cannot afford her tuition plus rent in nyc.

This thread brings back horrible memories! 😱
heh - just teasin. I actually liked chem in HS, but not AP chem (because senioritis had set in). Chem in college was a joke.
...Hell if I remember any of it though. 😛

Lol. You guys are giving him good advice, but his Chemistry Regents is on this Wednesday. I doubt that he will buy a book now and study? There is no time now. Damn it. I have to take the Physics Regents this week. It sucks. I don't know much because, I had this stupid teacher from Ohio. He is a good human being and can make you laugh. He brags about Ohio all the time and makes a lot jokes during class time. Bottom line: He is not a good teacher.
Offtopic: How did your sister get into Columbia? I am going to apply there this fall. I did an internship there last summer and I am doing it again this year. I asked the professor to write me a letter of recommendation.

sounds like youve been preparing for a good school. a good recommendation from a prestigious internship could make the difference. i think my sister got in because she spent the last 2 summers of high school in madagascar, where she helped dig irrigation canals for the local villages. sounds like fun but you get the runs every day and the food (surprisingly) is not as good as nyc.

7) 2
8) 3
9) 2

33) 3
34) 4
35) 3
36) 1
37) 4
38) 3 (Fe is the only solid at room temperature)
Short Answer/Essay
51) 6 atoms
52) There are more gaseous moles of product than reactant (one and zero, respectively), and the universe tends towards disorder (entropy) therefore the reaction is spontaneous.
53) 10 neutrons
54) I have no idea what this notation is referring to. However, I can tell you that fluorine, in its ground state, has an electron configuration of 1s22s22p5. Typically, fluorine is found either as an ion (as in HF, a weak acid) or as a gas (paired with another Flourine atom). From my best guess from what the notation is showing, I would say that you can tell that the fluorine is "excited" because an electron has jumped from the second shell to the third shell, but I may be off in what I think that is saying.
55) C4H10 (Butane)
56) 780.64 grams
57) Well, I would presume that the direction of the heat flow is now going from the student's hand to the test tube.
58)
59) As the number of carbon atoms present in the molecule increase, the solubility of the molecule descreases.
60) 275 grams (1-pentanol has five carbons)

Not exactly. There's two Hunter schools now. One's prestigious (Hunter College High School), the other one...not so much (Manhattan Hunter Science High School).

ahh i see. but i thought there was one that started before high school. (im assuming Hunter College High School is really a hs.) because i took the test way back in grade school.

There's a Hunter College Elementary School that currently share facilities with the high school.

Hey Hummer, now that these geniuses gave you the answers, can you figure out the principles that drive them?
It's a good thing I have insomnia tonight. I googled some sites for you and the best one in the amount of time you have left is http://www.jesuitnola.org/upload/clark/links.htm (No, I'm not now, nor have I ever been, nor will ever be a Jesuit). Get off the friggin MR and get working😛

I think the answer to #10 is 6 electrons between the two carbon atoms. Carbon has 4 valence electrons (electrons in its outer shell) and slots for 4 electrons (which is why you always see it with four pokey bond thingies sticking out of it).
I would answer question #52 by noting that HNO3 is an acid and is therefore prone to spontaneous reactions (usually by jettisoning the H atoms for larger, more accomodating partners). I would not site gas and entropy and all that jazz, because some gases are extremely reactive (such as the explosive hydrogen gas given off as a byproduct of the reaction.)
For Question 67, you might get mega-bonus points if you can note the graph appears to be some sort of inverse logarithmic curve. (I hope I'm using the right terminology here. Any math people here?)

You should save the nerd alerts for when someone decides to whip out the redox reactions. 😛
