College personal Essay help.
I graduated high school in '09 and decided to take a gap year off before going to college for personal reasons. So now I'm pretty much through with my college process and finalizing everything. I need to get my personal essay in soon but my problem is that I don't have anyone to proofread it for me now for grammar errors or spelling errors. I've done as much as I could on my own, but not being in high school anymore with teachers who can proof-read it has made it a lot more difficult. I also don't really know anyone who's good at English to maybe finalize it for me. Maybe tell me where it could be stronger or fix sentence structure errors.

I was wondering if anyone would be willing to proof-read my personal statement for me. Correct grammar, spelling, anything that can be stronger. Also what kind of heading do colleges expect on a personal statement if any? Should I double space? It's only supposed to be 250 minimum words so I don't know. If this isn't acceptable here than please tell me and I'll remove it but I would like as much feedback on it as possible.

Thanks so much, and I've added my essay behind the cut. You can respond in a post or contact me through email if that's be better for anyone. Abell2221@yahoo.com

I need help with my English work, well it's not really work we've just all been given an extract of Duchess Of Malfi to 'translate' and I'm having trouble with my section.

I need almost a word-for-word 'translation' of these few desctiptions of the madmen from Act IV Scene II:


"an English tailor, craz'd i'th' brain
With the study of new fashion;"


"a gentleman usher,
Quite beside himself with care to keep in mind
The number of his lady's salutations,
Or "How do you," she employ'd him in each morning;"


"And let one broker that's mad loose to these,
You'd think the devil were among them."


And then the Duchess says:
"Let them loose when you please,
For I am chain'd to endure all your tyranny."


I'm sorry for basically asking you to do my (fairly easy) work, it's just that we're being made to tell it to the class and that makes me nervous enough so I'd just really like to know that what I'm saying is right!

Thank you so much for any help!

I'm a college student..
Need help with homework? Check out what I've already written on my academic blog, oxfordmuse (including chemistry help, anatomy help, and an example of how to write a history summary), or comment at my site and ask me for help in any class that I have taken/am taking, such as English, Sociology 101, etc. =]

Could anyone help me interpret/put a simpler meaning to this section of a poem? The whole poem is 'Crystal Night' by Lyn Lifshin, about Kristallnacht during the Holocaust.

windows slashed
like skin pulled
tight frozen with a stone slammed thru
it smashed blue

glass crystal a whole lake of ice
a plane crashes
into smashed tea cups

thanks

Hey
Would anybody feel inclined to proofread an essay? I'm interested in an opinion by someone who doesn't know me so there will be less bias.
Thanks

Please please please help
I am in so much trouble and I've never come down to this but I am BEGGING someone to help me with these two problems that I have for my chemistry homework.

A student mixes 0.400 L of 0.5M HCl with 0.250 L of 1.00 M NaOH. What would the Molar concentration of NaCl of the new solution be? What would the pH of the new solution be? If the solution were diluted 10-fold (to 5.75 L) what would the pH be?                
             
         I did this: 
           

Moles HCl = (Moles of HCl/Liter of HCl solution) X Volume HCl solution

      (0.5moles of HCl/1 liter of HCl) X 0.400 L HCl solution

      1.25 moles of HCl
But I have no idea if I'm evenon the right track....


The other problem that I have is:
 

Calculate the energy released (using bond energies) from 155 g of hexenoic acid

 

C-C     345 kJ/mol

C=C    615 kJ/mol

C-H     415 kJ/mol

C-O     360 kJ/mol

C=O    805 kJ/mol   (For carbon dioxide)

C=O    750 kJ/mol   (For everything else)

O-H     460 kJ/mol

O=O    494 kJ/mol

I found that 155g of Hexenoic Acid is equal to 2.418 moles, but I don't know where to go from here? Do I just put kJ/2.418 and then divide?

Could somebody please help me, it's been years since I've taken a math course. I know to cross multiply and use logarithms, but I don't remember how and the steps get messy on me.

(-.107)/(40^x) = (-.137)/(20^x)

If anybody can help me with this I'd really appreciate it, thank you :)

least common multiple
 Is there any easy way or trick to find the least common multiple of three (or more) different numbers? I seriously spend like 30 minutes when I'm trying to find LCM for rather large numbers.

This survey is for my sociology class... and while I need to really get only two (one with an adult and the other with a senior citizen) anything would really help me out here as some of the questions aren't something I can ask any of the older people around me (and honestly i find some of them offensive)
there's 65 questions but if you can do at least a half of then I'll be more than pleased.
I also might need you to post your age too and any questions that don't apply to you just skip.

( thank you very muchCollapse )
This will probably be cross posted to several communities so I'm VERY sorry if it floods your flist

Chemical Kinetics
Over the next few days, I'll be doing a homework assignment from my
textbook that is 27 problems long. I've already solved four of today's
nine questions, but these last five have me slightly confused.
Chemical kinetics really isn't my forte. Any help at all would be
wonderful.

1. The gas-phase reaction Cl(g) + HBr(g) ---> HCl(g) + Br(g) has an
overall enthalpy change of -66kJ. The activation energy for the
reaction is 7 kJ. What is the activation energy for the reverse reaction?
(My textbook gives me three equations:
A. ln k=-E_a/RT + ln A
B. ln k_1 - ln k_2 = (-E_a/RT_1 + ln A) - (-E_a/RT_2 + ln A)
C. ln k_1/k_2 = E_a/R(1/T_2 - 1/T_1)
Which of these, if any, would I use to find the activation energy?
Also, are there any additional steps to solving this, or would I be
able to stop after plugging and chugging into one of those equations?)

2. Consider the following reaction: 2NO(g) + 2H_2(g) ---> N_2(g) +
2H_2O(g)
a) The rate law for this reaction is first order in H_2 and second
order in NO. Write the rate law.
(Since Rate=k[reactant 1]^m[reactant]^n, would my rate law be 3?)
b) If the rate constant for this reaction at 1000 K is 6.0*10^4
M^-2s^-1, what is the reaction rate when [NO]=0.025 M and [H_2]=0.015 M?
c) What is the reaction rate at 1000 K when the concentration of NO is
increased to 0.10 M, while the concentration of H_2 is 0.010 M?

3. You have studied the gas-phase oxidation of HBr by O_2: 4HBr(g) +
O_2(g) ---> 2H_2O(g) + 2Br(g)
You find the reaction to be first order with respect to HBr and first
order with respect to O_2. You propose the following mechanism:
HBr(g) + O_2(g) ---> HOOBr(g)
HOOBr(g) + HBr(g) ---> 2HOBr(g)
HOBr(g) + HBr(g) ---> H_2O(g) + Br_2
a) Indicate how the elementary reactions add to give the overall
reaction.
(I'm guessing the coefficients for one of the equations will need to be multiplied by 2?)
b) Based on the rate law, which step is rate determining?
c) What are the intermediates in this mechanism?
d) If you are unable to detect HOBr or HOOBr among the products, does
this disprove your mechanism?
(Mechanisms were taught today in my class, and none of it made any
sense at all, so this is probably the one I need the most help on.)

4. The reaction 2NO_2 ---> 2NO + O_2 has the rate constant
k=0.63M^-1s^-1. If the initial concentration of NO_2 is 0.100M, how
would you determine how long it would take for the concentration to
decrease to 0.025 M?

5. The following mechanism has been proposed for the gas-phase
reaction of chloroform (CHCl_3) and chlorine:
Step 1: Cl_2(g) <---> 2Cl(g) (fast) [Note: k_1 is atop the
arrows, k_-1 is below the arrows]
Step 2: Cl(g) + CHCl_3(g) ---> HCl(g) + CCl_3(g) (slow)
[Note: k_2 is atop the arrow)
Step 3: Cl(g) + CCl_3(g) ---> CCl_4(g) (fast) [Note: k_3
is atop the arrow)
What is the rate law predicted by this mechanism?
(I'm aware this one isn't supposed to be an integer, but what is IS supposed to be, exactly, is what puzzles me.)

Buffers question
Twentyfive mL of a 0.075 M solution of a weak acid was titrated with 0.10 M NaOH. After the addition of 5.0 mL of NaOH the pH was 4.85.

a. What is the pKa of the weak acid?
b. If the solution at this point is diluted to 50 mL for use as a buffer, what is the
molar concentration of the buffer?

I want to solve this using the henderson hasselbach equation, because that will solve for the pKa directly. But i don't know the ratio of A-/HA

The moles of weak acid i found to be 0.001875mol. And moles of NaOH is 0.0005mol.
At first I thought the A- would be 0.001875+0.0005mol, and HA would be 0.001875-0.0005mol. Because when you add the acid, the equilibirum shifts to the right.

So using this method i found the pKa to be 5.08. This might be wrong. Any pointers would be great.

Hi, I am embarrassed to have to resort to this, but I have been stuck on these two problems for (literally) two hours.  Can anyone help?

"Suppose that 1.00g of hydrogen is spearated into electrons and protons.  Suppose also that the protons are placed at the Earth's North Pole and the electrons are placed at the South Pole.  What is the resulting compressional force on the Earth?"

I've gotten several answers for this, but none of them correct (5.12x10^5 N).  I suspect my error is in assuming that the q values are related to the masses of the electrons and the masses of the protons?

"Two identical conducting spheres are placed with their centers 0.30m apart.  One is given a charge of 12x10^-9 C, the other a charge of -18x10^-9 C.  The spherers are connected by a conducting wire. Find the electrostatic force between the two after equilibrium is reached."

I thought this one would be rather straight-forward, but I keep on getting very large numbers instead of the correct one, 9.0x10+-7 N.

I would appreciate any thoughts on this.  We are allowed to consult others on the homework or even go to our learning center, but they are closed for the night.
Thank you ahead of time for at least reading this!  :)

S.O.S., emergency! ALGEBRA AND THEORY OF NUMBERS

dear members of community, i need your help a lot!

the problem is - i can't find any info on topic
"theory of divisibility in the ring of polynomials with TWO variables and their usage"

i've looked through all catalogues of our uni library but in vain, there is only one Russian book which is not enough for my research. 

if you can advise relevant links on free e-materials or send me the scanned books on topic (bereginya4891@ukr.net), i'll be very-very grateful!

THANKS IN ADVANCE!

Hello,

Is there anyone here who has a background in science willing to check a biology lab for me?

Please let me know soon.

Thanks.

suggestions for an interesting/fun informative presentation (aka speech) topic?

it can be about a person, place, thing, idea, a how to, or ANYTHING.
it just has to be completely unbiased.

Calculus Problem
Hi, everybody. I have a problem that I need some help with. I think I'm just frustrated, but...
For what value of k does the equation e^2x=k(x)^1/2 have exactly one solution?
So far, I've tried to take the natural log of both sides and I solved for k. However, it asks for values.
Any help would simply be awesome =)
