1) Yes, Cl2 is definitely produced, we could see it, it stung our noses and we tested the gas. I know it's annoying, but please help! 2)Thank you!

so I don't have to do any Permutations right? just a simple Pr(E)=n(E)/n(S)

thanks =)

So there is no way profit = price x quantity demanded because I have q=-60p+950 and Revenue or profit=-60p^2+950p. I then have to find out the profit made by selling things at 5.50, 10 , and 15 dollars. I was told to plug these numbers into -60p^2+950p to get the profit and determine which one gives you the most profit.

Thanks, that's what I got :)

Ok, so I have DeltaHrxn=(X+90)-(143+90). How do you calculate the enthalpy of O2 (X above) when it is not given to you. Am I even doing that right?

For many people, the image that comes to mind when they hear, the word slavery is the Transatlantic Slave Trade. We think of the buying and selling of people, their shipment from one continent to another and the abolition of the trade in the early 1800s. Even if we know nothing about the slave trade, it is something we think of as part of our history rather than our present. But the reality is, slavery continues today. After reading Francis Bok "Escape From Slavery: The True Story of My Ten Years in Captivity – and My Journey to Freedom in America," I realized slavery is not ancient history. Slavery is still an issue all over the world. This book is so descriptive that it makes you care about the issue, it makes you want to do something to help. This book not only informs you about this issue but also helps you as a person. In Sudan, Africa's biggest country, chattel slavery is making a comeback, Arab militias, armed by the government, have been raiding African villages, shooting the men and enslaving the women and children. These people are kept as personal property or taken north and sold. This was the case of Francis Bok. In his autobiography Francis Bok told the story of his life and how they captured him in a raid at the age of seven. An Arab family enslaved him for ten years and Bok escaped in 1996, only to be enslaved by local police officers for two months. An Arab truck driver helped him flee to Khartoum, where security forces arrested and jailed him for seven months. He fled to Cairo when he was released, and in 1999 the United Nations helped him move to North Dakota. Bok has since addressed many members of Congress about the enslaved Sudanese people. He was the first escaped slave to testify before the Senate Committee on Foreign Relations in 2000. Now He works for an anti-slavery group. He said, “ I will not rest until I see my people free.” Finding this out made me realize that slavery was probably not only an issue in Sudan but all around the world. In fact it is. Contrary to popular belief, slavery did not end with Abraham Lincoln in 1865. Experts estimate that today there are still twenty-seven million people enslaved around the world. It is happening in all six inhabited continents, which includes the United States. The CIA estimates 14,500 to 17,000 victims are trafficked into the "Land of the Free" every year. This book made me view the world differently. It made me realize that people have not learned from the mistakes of the past. People are still enslaving others and that is not right. Something must be done. The only way it will is if people do something about. Everyone deserves to be free. This book encourages you to do something but also helps you become a greater person. After reading this book I began to see life in a different way. I realized one should never give up always keep trying because some how some way things will change but they only change if one keeps on trying. If this man was once a slave, escaped and now he is an important abolitionist then why can something one believes in also happen. It makes you a stronger person. This book has made me keep trying when things get tough I just think of Francis Bok and I know I can do anything.

my essay is longer but it won't paste

Well 3x * x^2 = 3x^3 So now you have 3x^3 = 4 then x^3 = 4/3 so x = the cubed root of (4/3)^(1/3) Where ^ indicates "to the power of".

Whoops, the answer should just be x = (4/3)^(1/3) or x = the cube root of (4/3) Bad grammar :P

The "square root" of a number simply means the number is raised to the power of 1/2 or 0.5. So your question becomes (((125)^1/2)^4)^1/6 When you have exponents beside each other you simply multiply them. So the question becomes 125^(0.5*4*1/6) = 125^(1/3) Now what number multiplied by itself 3 times gives you 125?

Did you teacher actually say that's why you lost 2 marks? It might have been lack of decimal place(s) or an incorrect answer. Triangles can definitely have decimal angles.

5^3 = 125 So how do we get 125^(1/3) from this? Simply take the cubed root of both sides. (5^3)^(1/3) = 125(^1/3) What then, must the cubed root of 125 be?

No problem :)

I'm assuming length is depth. A rectangular solid has 6 sides, so the total area will simply be 6 times the area of one side. The area of one side is the area of square which is w*h. The volume of a rectangular solid is l*w*h. From Google, "The lateral area is the surface area of a 3D figure, but excluding the area of any bases." So if you were to take the solid and flatten it, you would get the area of four sides. Lateral Area = 4*h*w

"If the sequence An converges to 0, and each An is smaller than An-1 (i.e. the sequence An is monotone decreasing), then the series converges." In this case, An = 1 / (3n + 1) The limit as n->infinity (An) = 0 A1 = 1 / 4 A2 = 1 / 7 Therefore, by the Alternating Series Test the series converges.

Whoops, I read those numbers wrong. The area of two sides will be l*h and the other four will be w*h. So the total area = 2(l*h) + 4(w*h) Sorry about that :S

First you have to expand your terms. 7y^2 - 5y^3 - 180y^2 - 55 = -100 Collect like terms. -5y^3 -173y^2 = -45 now factor the y^2 y^2(-5y - 173) = -45 There are two solutions to this equation. y = 0 and 5y + 173 = 45 which yields y = -25.6

n is the number of moles. It's usually equal to one to simplify matters.

For a right angle triangle the following equation is true: a^2 + b^2 = c^2 Where c is the hypotenuse of the triangle and a,b are the other sides (you decide which side is a and which side is b).

I'm not familiar with that particular term, but mach number .85 could possibly mean 0.85 times the speed of sound.

What exactly is your question? I don't even see a denominator anywhere :) What you have is right so far. If you want to finish that question you need to use the quadratic formula x = (-b +/- square root(b^2 - 4ac)) / 2a x = (5 +/- square root (25 + 192)) / 16 x = (5 +/- square root (217)) / 16 which yields x1 = 1.23 and x2 = -0.61

Your solution is perfect, did you just want confirmation?

To answer Writeacher, we didn't say that there weren't similarities, we just said that they aren't the same religion. I can say quite firmly that Judaism and Christianity are not too similar, let alone Islam and Christianity. I would not say that Jews and Christians worship the smae God, let alone Muslims and Christians because Christians believe that God is trinitarian (three parts - the Father, the Son, and the Holy Spirit). Christians believe that Jesus is the Son in this trinity. Jews only believe in God the Father and reject the half of the Bible called the New Testament. Muslims believe in a god who is a different god than is represented in the Jewish and Christian scriptures. They believe that Jesus was born as a prophet like Moses and Mohammed. They believe that Jesus did not die on the cross but that he was taken up to Heaven to be spared from humiliation. The similarities between these religions rely on their place of origin, namely the Middle East. The cultures of these places would lead to the developement of similar religions (and also because the Muslims did descend from the son of the Jewish patriarch Abraham).

emf sets top most node to emf V. Nodal at top node: (emf - V)/5 = 2A => emf = 43V ohms law at top node: (43V - 33V)/12 = Current right branch = 0.83A Current in left branch = A + 0.83 = 2.83A R = 33/2.83 = 11.66 Ohms Although, this question is a little odd because there's no ground.

Not enough information. However, if the problem gave Harry's total amount of money, or a percentage based on the 12 dollars spent, it would be solvable. Think about how you would solve it if this information was given.

Citric acid is a moleule with entirely covalent bonds. Covalent componds can dissociate (weakly) into ions in solution, after all water itself dissociates to a small degree. Citric acid is an organic acid; it does dissociate (weakly) however the bonds that hold the hydrogens that ionize to the backbone are indeed covalent bonds. They can split fairly easily because of the double-bonded oxygens. When the hrogen leaves the extra electon can resonate between two adjacent oxygens.

H=7 -8 cos (2 pi t/3) seems correct, I didn't check your math though. If H is the height of the initial point after t seconds, simply set t = 5.5 seconds and solve for H. H = 7 - 8 cos(2pi*5.5/3)

If I start the introductory paragraph to: As a candidate for National Honor Society membership, I believe that I exemplify the high standards expected of its members. Would I need to add on more to it to make it a little bit longer? I was thinking about adding this to it: I exemplify good character and maintain exemplary grades. I also posess the ability of a leader to otheres. This year, I am going to try to contribute to my computer the best that I can by performing services that will better not myself, but my community aswell. Do you think that is good to add in the introductory?

Also whats a good way to end your paragraphs? do i just restate what i wrote?

My Prof. used the equation ---- (G*Me)/((Re+h)^2)=g' He said to solve for h which is what I did but it didn't work. Suggestions?

can't convert ml to grams

1 gallon toluene = about 3,785 mL density = about 0.867 g/mL mass toluene = 3785 mL x 0.867 g/mL = 3282 grams. C7H8 + 9O2 ==> 7CO2 + 4H2O moles toluene = grams/molar mass = 3282/92 = about 36 moles. From the equation above, 1 mole C7H8 will produce 7 moles CO2; therefore, 36 moles toluene will produce 7 x 36 = about 250 moles CO2.. PV = nRT– V=250 X 8.314 X 293 / 750 = 812 L

I'm not understanding. what do you mean figure the moles of H2O2 in 3.4 g of water? You get the same number of moles of water? I calculated: nH2O2 = 3.4g/34.02g/mol= 0.0999412 mol Water on the other hand has 18.02 mol sorry but I'm not understanding. I think for this particular answer I need help from the beginning because I can't wrap my head around what I'm doing.

thanks!

i've read most of these sites but couldn't really make sure of my answers i mean for example number 1 i was and still is confused between a and d ... i am not really able to comprehend the question. do you think my answers are right? it would really help

thank you...

Thanks, I wasn't able to get the second part of the answer (got a spring constant of 24.21 N/m) correct though.

For the second part, since this is a sine function, there's a particular angle that would have the same value as 0.8333. Like sin(0 deg) and sin(180 deg) equals to 0. So I did 180 - 56.4 to get that particular angle. Once I got that, I converted it to radians and repeated the steps you provided after that. Thanks for the help Damon.

velocity is speed with direction For example.... An airplane is flying East at 300 miles per hour Its speed is 300 miles per hour Its velocity is 300 miles per hour East

Frequency is the number of waves that pass by in one second. You know that 8 waves pass by in 30 seconds. How many pass by in 1 second? Period is the time it takes for one wave to pass by. Period is the inverse of frequency (T = 1/f). Wavelength is the distance measured from crest to crest. The speed of the waves can be calculated by multiplying wavelength by the frequency.

This problem can be solved with the conservation of energy. The total amount of energy in the car is the same before and after the collision with the spring. The car's kinetic energy before the collision is completely converted to spring potential energy after the collision. 1/2 * m * v^2 = 1/2 * k * x^2 Plug and chug, solve for k

Thanks a lot man!

Thank you!!

Start early - plant germination takes time regardless of the plant. Also you must be sure to replicate each plants environment as much as possible. Same potting soil, same sunlight, same amounts of liquid at the same time. Also you should have a control group. Since you are testing the effectiveness of growth based on type of liquid you should have one seed potted exactly the same but gets no liquid at all. The key to any good experiment is to isolate the variables you wish to test. Best of luck

The best thing I have done for conversions throughout all of my education was learn this saying: Kings over Humans over Dragons over Dogs over Cats over Mice (or if you prefer: "King Henry Died Drinking Chocolate Milk) broken down that gives: K H D * D C M this is short for: Kilo, Hecta, Deca, Deci, Centi, Milli Insert at * with grams meters or liters start with and point at what you are given (meters) and count how many to what you want (millimeters). then move the decimal point either left or right as many spaces as you counted ex 1.56 km --> ? cm K H D meters D C M 1 2 3 4 5 6 (move the decimal six to the right) 1.56km --> 1560000.0cm

Post one or two new concepts you learned from each of the PhxKlips

x=speed of boat in still water. assuming the problem implies 26 miles each way. to figure this out, I wrote this out in simple miles per hour terms. Example: (hours/mile)*miles + (hours/mile)*miles = hours so: (1/(x+5))*26+(1/(x-5))*26=10.6 x+5 represents the speed of the boat traveling with the current x-5 represents the speed of the boat traveling against the current Hopefully this gets you far enough to come up with about 8 miles per hour.
