thank you very much, Ms. Sue! Have a wonderful day!

What is electricity? and how are nuckears involved?

Thank you!

the smallest part of a compound?

what is the define?

thank you

found it rats but thanks

what part of speech is all

you have to sent up a given and then a prove staement and drwa a diagram

1 is Christopher Columbus

paying attention?

I think you mean "diagonal," not "diagnol."

Can you please explain to me how drinking tea is "effective and relevant" to getting good results? I don't understand.

That's what I was thinking Thank you

You must have missed my second response. I changed my answer, therefore I assumed you were responding to that.

I drew the sketch, the problem does not tell me how high he is initially, I can find the equation vfinal = the square root of (2gh) but I don't know what h is.

never mind, I figured it out.

Thank you SO much! I didn't realize i had to do 27(1-cos33)

multiply both sides by six which gives you 3xa = 12 then divide by 3 which gives you xa = 4 then if you are solving for x, divide both sides by a which gives you x = 4/a if you are solving for a, do the oppisite.

well, for the first one, I changed the rev/s to rad/s which was 8.275 rad/s and then i divided that by 5s to get the angular acceleration and then mulitiplied it by the radius (.1524m) in order to change it to tangential acceleration but it said my answer was incorrect.

and for the second one, i took the rad/s and multiplied it times .1524m to get m/s and it said i was incorrect again.

I tried to use V^2/r = GM(earth)/r^2 but I am not getting the correct answer.

oh wow, thanks.... wish I would have thought of that. it worked.

thanks again

so i did that and I got 4.0 X 10 ^16 and it's still wrong...am I just missing a conversion somewhere or something like that?

never mind, i got it. thanks so much!

Yes, I went back and changed the answers that Anonymous, said were wrong on the other post. I was needed someone to re-check my new answers for me...Thanks for the help.

Would these be the correct answers? 1. C 2. D 3. B 4. D 5. D (which was my original answer)

Thank you very much SraJMcGin for all of your help. I really appreciate it.. :)

I have looked most of these up and found the answers but there are some that I could not find, that is why I was wanting someone to check my answers.

I thought I was to use a formula n=cXv. I had NaS c=.002 L V >01 mol/L Therefore I got NaS as .00002. So I had Na S as the limiting reagent

I do not know where to start with this question. How can i find a substance that will form a precipitae with the lead. Could you suggest one and the possible formula

3Ag2S + 2 Al -- 6 Ag + Al2S3 State the charge on each ion in each of the comounds listed. I am having a hard time understanding how to do these redox questions

I am sorry could you give me a hint. I have read it over quite a few times. I still do not see where there are juxtapositions

A rate is the increase between the time(seconds) and distance (meters).

630. i was confused about the rounding up or down of five.. some say down and some say up.

thank you!

thank you very much damon!

According to the characters in the book, their lives have been improved. Through genetic engineering everyone is conditioned to love their job, social class, and lifestlye they are "destined" to have. Reading, I think it ways it has improved; however, this presents many drawbacks. They do not know the concept of family or love. They have no clue what it even feels like. They also have no say in their aspirations or social rights. (As I said earlier, they are conditioned for their destiny -- chosen by a man) The motives are simply to produce humans that love their jobs to improve the efficency of the workers in the work place.

Yes you would multiply this. And assuming the tank is empty that is the correct answer

They are "renewable" resources, and less polluting

disregard. I figured it out

median is the middle number. so put the numbers in descending or ascending order and find the middle number. It would be 1,700

mechanical energy is the sum of kinetic and potential energy. there fore the one who says that there is mechanical energy is correct. Because there is potential energy present

a=Pe^rt a=25000e^(.0575)(7.5)

work=force*distance work=800N*100m

semiannual means twice a year. so 2*5=10

draw out the picture of the trapezoid. Since it is a regular trapezoid the bottom angles on both sides are the same. If you draw imaginary lines from the top to the bottom you can form a figure composed of two triangles and 1 square in the middle. You can then use some right triangle trig to determine the height. The hypotenuse is 250'. the bottom of the triangle is 500/2. so it is also 250'. use the pythagoream thereom to find the other leg

a=P(1+(r/n))^nt

yes

49=x+(x+9)+(x+4) 49=3x+13 36=3x 12+x so one side is 12cm, on is 16cm and one is 21cm

force=G(m1m2/r^2) G=6.673x10^-11

bayside=5 lincoln x+1 hendricks=x band 20=5+x+x+1 20=2x+6 14=2x 7=x so hendricks has 7 and lincoln has 8

Thanks. I was messing up the change in velocity part

no that is not a problem. I just have to put in the number. the label is provided.

I figured it out. the velocity of the recoil is in the negative direction.

both

There are 9 calories in a gram of fat. 9x9=81 calories. 81/115=70.4%. C is the correct answer

it takes 5 minutes to make 2 cuts to give you 3 pieces. so if you continue at a rate of two cuts per 5 minute and in order to get 9 pieces you need 8 cuts. so I think 20 minutes

Kim weighed 6.5lbs which is the same as 2/3t+3. so 6.5=3+2/3t 3.5=2/3t t=5.25

chloride is a form of chlorine

5/3 x 3= 15/3 or 5 cups

a^2+b^2=C^2 x^2+(x+1)^2=5^2 the other legs are 3ft and 4ft

Disregard. I figured it out

Harvard?

A is wrong because they could have more or less children. C is wrong because it is impossible to have an aa child with the genotypes of the parents. And D is wrong because A is wrong. If you draw out the punett square you would see that B is correct

ride=.40+.15x

-21+3x

27-2x

4-12x=??

3 feet in a yard 12 inches in a foot. 12x3x10=360 360/10=36 tiles

-9+3x=??? if you still need help let me know

draw a picture, hint its more then 10 but less then 16

30/40=.75 .75x100= 75 percent

sqrt(75)=sqrt(25)sqrt(3) which simplifies to 5 times sqrt(3) so 6x5xsqrt(3)= 30 sqrt(3)

12 tablespoons cause 16/4=4 so, 4x3=12!

0.3724 g x 26.98MW = 10.05 mol -538.4kJ x 10.05 mol = -5410 kJ/mol 5410 kJ/mol of heat is evolved?????

yes, Al3+ sorry. so the moles=.01380. Could you help with the equation?

A 40-kg cart moving at 120 km/h collides head on with an approaching 50-kg cart, moving at 20 km/h ( in the opposite direction). if the two carts stick together what will be their speed?

So what are the answers for deltaS(sys)=? J/mol*K deltaS(surr)=? J/mol*K deltaS(univ)=? J/mol*K I need to verify the correct answers. Could you please tell me...Thanks!

Also I don't know how you are working this problem out.

DrBob222 could you please answer!!!!!!

Yes it is correct! Thanks! :) I see my mistake!

My answer is: deltaS(sys)=654900J/mol*K deltaS(surr)=466.4 J/mol*K deltaS(univ)=655366J/mol*K Sorry I forgot to convert to J also I checked this problem and I only got thedeltaS(surr)=466.4 J/mol*K correct. Please help

chemistry - Kelsey, Thursday, March 15, 2012 at 1:16am My answer is: deltaS(sys)=654900J/mol*K deltaS(surr)=466.4 J/mol*K deltaS(univ)=655366J/mol*K Sorry I forgot to convert to J also I checked this problem and I only got thedeltaS(surr)=466.4 J/mol*K correct. Please help

also I checked this problem and I only got the deltaS(surr)=466.4 J/mol*K correct. Please help

Everything is right except the system...i put -253.5 and it marked me wrong :(

is 3 -1? and im not sure what i did on number 1 ? please explain.

Yes thank you!
