thank you. i'm confused thought....i tried to use a formula that already had molality in it because i don't have a mass to use, hence the g/GMW kg portion. i need to use 175 mL and make it boil at 245 degrees F.

thank you so much! the molar mass was a major problem...i didn't realize i was so off. thank you for pointing that out.

thanks!

oui, partager [the infinitive of partage] means share.

the atomic mass in the periodic table represents the number of grams per one mol of lead. so there are 207.1 g per mol of lead.

nucleotide monomers a nucleotide is composed of: A Nitrogenous Base (purine or pyrimidine) A Five-Carbon Sugar A Phosphate Group

Oh okay so for this one would it be: 40 Ar 18???? thanks so much for your help!

yeah that's right, can u go on?

well, i got: (-4/5)(12/13) - (4/5)(7/13) therefore (-48/65) - (28/65) therefore: answer = (-76/65)

i knew that was wrong, coz my answer should be in the 50's haha..thanks though, great help can i ask how you got sinA and sinB with that information :) no point in me just copying it i would like to know how you got it

thank you!

Do i mulitply the equation my 5,3?

kk ty bro

Ok thanks, I did make a typo my bad.

I tried using 1E13 as q1 and -1.6E-19 as q2, and I still got it wrong...

1.44x 10^25 atoms c X 1 mol C / 6.02 x 10^23 atoms C = Type in calc. The atoms cancel out and you have moles =).

thank you

That doesn't help I am still confused

A car moves at 12 m/s and coast up a hill with a uniform acceleration of -1.6 m/s^2..What is its displacment after 6 sec.? What is its displacment after 9 sec.?

During takeoff, an airplane's angle of ascent is 16° and its speed is 300 feet per second. (a) Find the plane's altitude after 1 minute. (Round your answer to the nearest whole number.) ft (b) How long will it take the plane to climb to an altitude of 10,000 feet? (Round your answer to one decimal place.) sec

Yes, well kind of. I mean I want to see if there's a correlation between the standardized test scores of someone who participates in music compared to those who don't (participating meaning those who are in chorus, band, orchestra or simply a class about musical appreciation)...He mentioned how mine was more of an pure research paper because I talked about my experiences in music. I thought using real life examples would make the paper better but apparently in applied research you don't want to talk about yourself at all so I'm confused. According to the articles pure research and applied has similar characteristics and is difficult to tell the differences between them, which is confusing me even more.

Thanks but I don't really get what your saying? Does that mean your saying government regulation helps keep things in order? Does that mean it's necessary though i really don't know? Do you have any links about this subject because I need to write about 1-2 paragraphs about it. Thanks

Oh Sorry I thought it was rhetorical, but I would have to say Yes to all of them, which I guess would mean it's necessary for government regulation for most businesses. Are there any cases where it's not necessary though?

Oh wow! I guess I never really noticed that. I can't put my finger on the tone of the piece though. I can't think of a word to really describe it.

Thank you so much! When I say tone, I'm referring to the feeling behind the passage.. Ex: Dr. Seuss writing has a light, whimsical tone. Or Joan Dilard tends to be very dark and brooding.

it isn't necessary to change the mass in grams to moles. the equation reads out q=s*m*(final temp - initial temp) where q is the change in enthalpy, s is specific heat, and m is mass.

oh okay-thank you

y=5x+3

Thank you for doing that-I really appreciate it-I'm alittle confused on this stuff

Thank you very much That was pretty funny about me eating myself-thank you for pointing that out-my teacher would have thought I was muy tonto!

This is a diffeent one that the one you checked earlier and thank you again

Thank you so much-really appreciate it-

so I need to search the internet for why my experiment works? because I already came across these two sites and they did not help.

not a specific question but I have to make a poster with my experiment-balloon, baking soda and vinegar each step of the scientific method. but stuck on research.

thank you-would this be correct Vinegar with Baking Soda mixed together creates an acid-base, making a gas. The gas pushes up into a balloon and causing the balloon to blow up.

thanks a lot.

Write a program to determine a person's weekly pay, where they receive time and a half for overtime work beyond forty hours.

thanks! Just as I thought just wanted to make sure

I believe the answer is *A. Decision makers or opinion modelers in an organization* because in the Business Communication book I have, under the caption "Identify Your Primary Audience" it states, "For some messages, certain audience members may be more important than others. Don't ignore the needs of less influential members, but MAKE SURE you address the concerns of the key decision makers." The emphasis on addressing the concern of the "key decision makers" leads me to believe that decision makers should always compose the group of primary audience members being addressed.

Suppose you pour 15 g of hot water (at 55 oC) into a glass that contains 20 g of ice (at - 10 oC). Neglect the heat absorbed in the glass itself. a. How much heat would the water give up to get cooled to the melting point? b. How much heat would it take to get the ice to the melting point? c. Would some of the ice melt? d. How much would melt?

I did this problem for homework so here is my homework lol but remember DON'T COPY THAT IS AGAINST THE LAW! So I know the problem or question it is asking is “How many videos would you have to rent each month to make a membership worth investment?” and that's the gist now I just need to figure it out. What I know:the monthly fee is $30, club members pay $0.85 to rent each, non members pay $2.25 to rent each. What I need to know:# of videos to rent each month to make it worth the investment. The strategy i'm using for this problem is setting it up in a simple mathematical solution. 30 + .85n <= 2.25n and solving it from there. Solving The Problem: so I started with 30 + .85n <= 2.25n and n=# of movies rented. Then I reduced it to 30<1.4n by doing 2.25-.85 and then plugging it back in to the equation. Then I reduced that to 21.4<n by doing 30÷1.4 and then plugging the answer back in to get a final answer of 21.4<n. Thus proving my answer is correct. Conclusion: So the answer to the original problem “How many videos would you have to rent each month to make a membership worth investment?” is if u rent at least 22 videos pur month then u should join the club. This is a reasonable answer to the question because based on all the facts that I have shown on solving the problem proves that the answer is right making my answer a reasonable answer.

you did it right up until: t = log(920/314) = 0.465, I have no idea how you got those numbers but it's t(log(1.05/.92))=log(1000/300) t(log(1.1141304348)=log(3.3(rpt.)) t(0.057401472)=0.522878745 t=(0.522878745)/(0.057401472) t=9.1092

still confused

thankyou i appreciate it

thankyou i appreciate it could u however plz explain how u knew 1 mol of ag =108g

never mind i know now thankyou

c, more solids(glucose) outside cells in the blood plasma means the water in the cells will move out into the plasma through osmosis.

V=lwh V=k*k-1*k-2 V=k^3-3k^2-2k

or if your teacher wants it in this format V=k(k^2-3k-2)

consecutive integers are integers like 1,2,3 or 3,4,5 or 101,102,103. So since the largest of the integers is k, to get the consecutive integers lower than k, you have to find the second integer which would be k-1, then the third which would be k-2.

This is a repost from earlier. I thought it didn't go through so I typed it again.

I believe the correct answer is 0.635 but i got 0.625.

you would calculate as follows: Only the income that results from this project is going to be counted. So, all "currently sells X at $" info is ignored! New project: 20580 x $11760 + 4900 x $44100 + -1274 x $83300 (we sell less of these) =351986600

The best answer is D A - sometimes, in questions like these, the examiner discusses the building/land cost. But they say they could sell it / lease it at X amount today. That sale would be an "opporunity cost" - and it would be counted. B - Just the oppoisite of what I said about A. If the equipment could have generated $200k, than that is an opportunity cost and it is relevant. C - These costs would form part of the fixed costs. That is necessary when calculating the sale price, and also eventually tax to be paid. D - The building was renovated 2 years ago. Therefore it is NOT a cost that was caused by deciding to go ahead with the project. It is a sunk cost, and therefore not relevant to this project.

In other words Statements A-C are all false. D is true.

One staple is probably to light to pick up on the balance. Let m = mass of one staple. 210*m = 6.8 m = 6.8/210 m = 0.032g

0.45

60kg

Moment of Ineria= 1/2 MR^2 = 1/2 (3.565kg)(0.0950m)^2= 0.016 kg.m^2

They want the answer in radians not degrees. So it's pi/2

0.160kg

either throw the jetpack where he doesn't want to go, so away from the space station, OR JUST CALL ANOTHER ASTRONAUT OVER THE RADIO!!! If the jetpack runs out of fuel, that doesn't mean that the battery of his radio and other systems is dead!

throw it away from the station with as much force as she can, and make sure she doesn't miss, so she will float back to the station

Thanks you! I got the answer!

I have improving Vocabulary skills 4th edition and I need chapter 1 sentence check 2 answers

But "I" is the subject and you is the object.

So my original answer is correct You and I

You would say for me. So it should be you and me since its in the objective form!

4L

X=8 28(8)÷4=56

11580sec

1/8X 20=2.5.therefore each dose contains 2.5ml

From the equation,1L of N2 produced 2L of NH3.1.26L of N2 will produce 1.26X2/1=2.52L of NH3(Ammonia).

It's molecular mass is 2.The compound is H2O2.

1 Correct,2 incorrect, 3 right, 4 wrong, 5 right, 6 yeah, 7 wrong and 8 correct.

28.11 i got this but 29 is the answer in my text.

Actual mass=47.623-46.719=0.904g. mass of CaCo3(Ca=40,C=12,O=16X3=48.40+12+48)=100g %=100/1.631X100

Phylum in the animal kingdom rather.

Yeah.it's a must you put 'the'

75.55.

7.55 rather

Thanks a bunch!

Thanks.

I mean what is can the name of this enhancer be?

2SO2+O2=>2SO3 From the equ,1Cm3 of O2 formed 2Cm3 of 2SO3.Therefore, 5Cm3 will be formed by 5 X 1/2=2.5Cm3 of SO3.

Of O2

5Cm3 Of SO3 will be formed by 2.5Cm3 O2.

i'm not talking about location but functions and actions.

yeah.
