This is the equation ln(P2/P1) = -DHvap/R * (1/T2- 1/T1) but how do i get the pressure values and tempature values?

The total pressure in a flask containing air and ethanol at 257C is 878 mm Hg. The pressure of the air in the flask at 257C is 762 mm Hg. If the flask is immersed in a water bath at 400C, the total pressure is 980 mm Hg. The vapor pressure of ethanol at the new temperature is mm Hg. Hint: you will need to correct the pressure of air at the new temperature using the Gas Law: P1T1 = P2T2

Ms. Sue, I belived, the rhetoricla device was euphemism because the late-term procedure was adopt. On the other way, the opposition refer to the different bill name. Kevin,

Writeacher, I believed, the fallancy was a scapegoating because the author was blaming the representatives should have the integrity. Please advices,

The first thing that you to is distribute the -5 to both the terms in parenthesese. So you get -10W-5=25. than you add five to both sides and get -10w=30. The last thing you do is divide both sides by -10. w=-3.

it does boil at 100c I have tred it with a science project in fourt grade

Hey Fubu what is up. BTW, the scientific name is the same.

I'm guessing you know who I am Fubu...I'm kinda stuck on the Cyanobacteria classes.

LOL, y do your guys all post here about the project. I think he means Prochlorobacteria... I thought you quit biology hnrs Clair.

I need to unscramble E O E R A A R V N D E I H R S E H V D L N E R L F E A G.......It has something to do with Christman

NH3 is a base because it accepts a proton from H2O.

So q=mc(Tf-Ti) could be written as Delta H=mc(Tf-Ti) assuming the pressure is constant?

That's very cool! Thank you for your time!

I am coming up with (-5,-2,4) for my answer and I see you x=5

So would it be rate = (10^-7)*(10^-7)*(1.4X10^11)

Give them fish they will eat for a day. Teach them to fish they will eat for years. With regard to low income countries and based on your knowledge and understanding of culture, society and social stratification provide support for or criticism of this statement.

I totally agree with the statement. Everyday people around the world is trying to make life better in some kind of way. I think showing these people new skills and ways they can benefit from it, people would be more excited to learn new things everyday. I think it would be better to show them how to get their own food rather than someone handing it to them. By teaching them now they develop a way to provide for themselves. I believe that if they practice and learn new skills that is can help there culture and community.

The origin is (0,0) Both the x and y intercepts at the origin are always 0.

just throwing out a number because i'm bored: 55.8741 was what i got. I'm no chemist, but i wanted to take a shot at it and now i'm curious how close the real answer is to mine.

Area equals length times width. A square has equal length sides so the answer is a number times itself that comes out to 400. 20 x 20 = 400. The length of each side is 20cm.

write out a number line from negative ten to positive ten, then you can have a visual reference to go by. Here is the order: -5,-7/8,-5/6, 6, 8. (least to greatest) fyi... -7/8 = -0.875 -5/6 = -0.833

so in other words, it took 1.5 hours to travel 150 km. Therefore, if you want velocity in km/hr it is 100 kilometers per hour.

Unless i'm missing something, you have everything set up already. The total volume is 206 cm3, so if the flow rate fills 15.5 cm3 per second, it would take 13.29 seconds to fill the container. 206/15.5.

the speed of light is 300,000,000 meters per second. 4x10 to the 8th is 400,000,000 meters. distance divided by the speed of light gives you the answer, 400 million divided by 300 million equals 1.33, therefor it would take 1.33 seconds for the signal to get to the moon.

The one we used was sodium hypochlorite (NaOCl)

I still think its #1? is that correct?

I believe the 1st question is number 2. & the 2nd question is number 3. Can anyone confirm this. Thanks.

Ok really I don't know all of the steps but if you look at the da/dt of a) and put it over the dh/dt of b) then you get your answer. I don't know. I'm doing it right now. God Bless!

Microbiology affects a person on a daily basis because it starts from the things that we do to the things that we don't. Such as when we take Omega 3 Fish Oil Supplements, the oils, and the vitamins from within, helps us daily, without us even knowing about it. Or when we wash our hands, sometimes we can't see the germs, and bacteria on our hands, but they are there, and so we remove them by washing our hands.

Hey buddy, i'm pretty sure this is against the rules. just so you know, its unlikely that you'll get much help from this site. i think you should use a different site if you want help...the census, just a thought. best of luck to you, i can already tell you are going to win (haha) kev kev

Thank you so is the first one true as well?

Are both of these false A unique format is one for which there is no similar competition in the market. A) True B) False I also think this one is false but again not sure A "head to head" format refers to a format that is trying to successfully program against a similar one. A) True B) False

unique as in do they have a competitor

Never mind I'm not sure that's why i asked, how about the other question i think that's false do you?

i agree with the first one, but why would the second one be false? when somethings head to head wouldnt it be 2 programs battling and 1 trying to be successful?

you have to use the law of sines which a/sinA=b/sin B=c/ sin C where the top letter is the opposite side of the angle and the lower letter is the angle itself. first you would go about solving this for angle B by putting 12/sin 76=4/ sin B. doing simple algebra the equation comes out to (4*sin(76))/12=sin B then you take the inverse sin of both sides to get angle B. Once you have angle B all the inside angle of a triangle equal 180 degrees so solve for angle C by taking 180-A-B=C. Then you go about solving for side c using the same equation to find Angle B except it would come out to look like (a*sin(C))/sin(A)=c. You want to use side a and angle A because those are given to you in the equation and will give the best result. Hope this helped!

the first thing that you need to do is solve for x. The sum of the interior angles inside a pentagon is equal to 540 degrees. you come up with the equation 2x+6x+4x-6+2x-16+6x+2=540. Then you want to simplify it down to 20x-20=540. there are multiple ways you can finish this but it turns out to be x=28. then all you do is plug in 28 for x in all of the equations of the angles and you will find that 6x+2 is the largest one at 170 degrees. I would suggest that you try it out instead of just taking the answer though. good luck!

is that exactly how it is showed or is there a log base? normally that means theres a log base 10 and if that is the case the answer is 10^3.2. in a more general sense x=b^y and putting it in terms of y the equation is y=logbx were b is subscripted i just don't know how to do that on here. i hope this helps!

opps i suppose i forgot to give the temperature change and it was a +19 degrees celcius

use the equation drbob222 gave you before. its the right one. you may have to convert the 5 L to mL first though for it to work or understand that ur answer is in L and convert it. one or the other

yep

it makes sense too because if you think about it you are making a 5.0 L solution and 191.20 mL isnt even 1/5 of a liter

specific heat of h2o is 4.184

if im missing any info plz tell me ill get back to it asap. it was put in a styrofoam cupand the temperature of the solution was measured directly if that helps at all. i just need to know i guess whether or not im treating the data as a coffee cup calorimeter or doing something else with it. i can do the numbers i just need a push in the right direction.

you have to convert it from joules to calories and idk that off hand but other then that it looks good so far

theres 2 different methods u could do. u could solve for either x or y in one of the equations and replace the one you solved for. thatd be the easiest with those numbers

sry we have not gotten that far yet. wish i could help

yes

you have to keep in mind its asking for the greatest increase ionization energy when the between the removal of the first and second electron. That is basically saying it will lose 1 electron no problem but the second one would be a lot harder. therefore you would have to look to see which column willingly loses one electron but not two. so you would be looking for an akilli metal. atomic radius you were right about. your answer would be f for the reason i stated above

yep

you shouldve got a bigger answer and ur solving for the kj not kj/mol. remember you have to multiply the 2000 moles by the 4130 kj/mol to get rid of the mole.

you had it set up right before. ur messing up the algebra. you were solving for the x kj so in order to do that you would have to multiply both sides by the 2000 moles. the moles and 200o would cancel on one side and just the moles on the other. but your number is correct. if you want a better explanation fire away

now you just multiply them. the number you had before was right just not the whole cancelling out stuff.

alright. the first one would be easiest if you multiplied out the numbers before the parenthesiss into the numbers inside. so itll look like 50=3r+48-2r+4.the u can simplify the right side and get 50=r+52. subtract 52 from both sides and your answer is r=-2 the second one first you want to subtract 14 from both sides so you get 5(2x-10)/2=5. next you want to divide both sides by 5 because it works out very nicely and you get (2x-10)/2=1. next you can take out the 2 on the left because 2x-10 can also be written as 2(x-5) so you would get x-5=1. and lastly you add 5 to both sides so x=6

So when asked to draw the molecular orbital configuration, you draw the orbital configurations for each element in the compound while doing something with the pi and sigma bonds?

1 torr = 0.001316 atm Do the conversion now. (.001316 atm/ 1 torr) x 832 torr. This cancels the torr unit and gives you the conversion into atm. 832 * .001316 = 1.094912 atm

1 pound per square inch = 0.0680459639 atm (.0608 atm / 1 psi) x 17.4 psi. This cancels the psi unit and gives your answer in atm.

stroll is to walk opposite of enormous can be small or tiny, you choose opposite of release can be throttle or suppress, you choose sorry i do not know the first one

well there are several anwers to this problem, actually. here they are: 6.0831 6.0832 6.0833 6.0834

24 radical 152 is the same as 48 radical 38

Thank You!

i got the moles of Ca3(PO4)2=0.01275549 but how do i covert that to moles of CaCl2? using the stoichiometric ratio which is 1:1 or am i doing something wrong

In general, the orders (exponents) in a rate law can turn out to be positive or negative rational numbers, so -1 is a possibility.

14 x 6 / 28

Not even a question lol.

Helps a bunch thank you.

Just to confirm, the answer is 2.004748935 x 10^-5, right?

ah man. i've got this too. for anyone that can help, the fact that the electron moves at close to the speed of light and thus Einstein's theory of special relativity will effect any lengths (based on the reference point) has to be taken into account. i think. maybe not. but please keep that in mind when answering this

circumference of a cirle = pi x diameter. pi = 3.1415926535 (or just use pi button on calculator) Diameter = 2 x radius radius = 6380 (+620) or 7000km now you have all the info you need, plug in the numbers

I believe the elements with 8 electrons should be the noble gasses. Argon, Krypton,...etc.

though if you're going off of the mean (average) week 4 would get 55 customers oddly enough the median (middle number) is 55 as well. There is no mode (most common number) to calc. average, 30+55+80=165/3=55

The first answer is still correct based on trend so i would go with that

1/10 plus 1/10 gives you 2/10 or 1/5

This is saying that Kelly's sister is 1/2 the height of 144cm. 144/2=72cm So her sister is 72cm. if you want to convert this to inches, one inch equals 2.54cm.

thanks

well for the first one, should the answer be... K = [H2O]^2 ----------- [H2]^2 + [O2] or should it just be... K = [H2O]^2?

What volume of 0.1125 M K2Cr2O7 would be required to oxidize 48.16 mL of 0.1006 M Na2SO3 in acidic solution? The products include Cr3+ and SO42- ions.

no

Wait my mistake i mean regular price %25

Again $25 :P

a. Probability of drawing a white ball is 10(number of white balls)/ 30 (total number of balls) since the balls are replaced, the probability remains the same for the second ball, that is 10/30. To determine probability of drawing balls with replacement is found by multiplying both probabilities (10/30)*(10/30) b. Probability of drawing without replacement is slightly different from with replacement. The first white ball is still 10/30 but the second will be the number of remaining white balls (9) divided by the remaining number of total balls (29). To determine probability, multiply the probabilities of each individual event. Thus, (10/30)*(9/29)

Did you try velocity squared, then multiplied by the density?

Na+/K= pump, due to it being a active transport. Active transport requires ENERGY (ATP). The rest of the choices are all passive transport, which do not require ENERGY.

Passages 1 and 2 compose of similar knowledge to inform the reader of the Okefenokee Swamp. While the passages’ material may equally compare, the purpose and style of the pieces heavily differ. Passage 1 entails a concise expository that strictly informs the reader of various facts of the Okefenokee Swamp. Passage 2, on the other hand, dramaticizes the swamp to be something of a poetic environment. Properly sound, the first passage begins by educating the reader of the subject, setting, and geological aspects of the swamps; a fine start for an informative passage. The second piece starts off by describing the wild, metaphorical, and dramatic enterprise of the Okefenokee Swamp. Rather than a “saucer-shaped depression” (1), the Okefenokee is the “swamp archetypal, the swamp of legend, of racial memory, of Hollywood” (2). Also, the diction severely differs. Passage 1 recites professional and factual nouns i.e. the “swamp”, “channels of open water”, and “vegetation”. Passage 2 refers to the swamp as “here”, as if it is a story, and chooses words and phrases such as “birth to two rivers”, “equipped with beaks, talons, claws…etc.”, “they feed on each other”, “screeching”, and “hellish zoo”. It is evident that the straightforward diction and tone pertains to an objective purpose of passage 1 while a thrilling diction and tone is utilized by the second passage for a sensational purpose.

I think I need more help. I tried but I think I'm going in circles on this one and not thinking clearly at this point.

To keep the cylinder in equilibrium both side must be equal. (m1)*(v^2/r)=(m2)*g Left side=Right side (v^2/r) = (m2)*g / m1 isolate “v” on the left… v^2 = (m12)*g*r/m1 v = sqrt((m2)*g*r /(m1)) plug in the values and you are done… v = sqrt(2.5*9.81*.2)/(1.5) = 1.80831 Dr. Cooper will be proud of you. m1 = mass of the puck = 1.5 km m2 = mass of the cylinder = 2.5 km r= radius = 20 cm = .2 m (SI units) v = velocity g = 9.81 (if do not know what “g” is you should look it up) sqrt = square root

Rules for counting significant figures are summarized below. Zeros within a number are always significant. Both 4308 and 40.05 contain four significant figures. Zeros that do nothing but set the decimal point are not significant. Thus, 470,000 has two significant figures. Trailing zeros that aren't needed to hold the decimal point are significant. For example, 4.00 has three significant figures.
