Molecular chlorine gas and molecular fluorine gas combine to form a gaseous product. Under the same conditions of temperature and pressure it is found that one volume of Cl2 reacts with 3 volumes of F2 to yield two volumes of the product. What is the product's formula??

I have noticed a few times whilst watching tv that Americans have really large mouths compared to the rest of the world.

This trend does not seem to happen to any movie stars however (apart from Ange Joliey - but its her lips really) maybe they had mouth jobs?

Hi,

Consider the three charges in Figure P25.42 http://i137.photobucket.com/albums/q208/infinitbelt/p25-42.gif in which d = 4.8 cm, q = 8 nC, and the positive x-axis points to the right. What is the force on the 5 nC charge? Give your answer as a magnitude and a direction.

? N
? degrees counterclockwise from the positive x-axis


I tried doing F = (kq1q2)/r^2, but I keep getting 2.94 x 10^-4 N, but that is wrong. Any ideas?


Thanks

If you travel in a straight line in space, you will meet yourself on the way back. If this is so and you could travel at the speed of light how do you get to another universe?

They are less than a mm in size and almost invisible to they eye they have been bothering both me and my cat for the last three months. They like to land on my head in my hair and around my eyes and may be carnivourus or parasitic. they are too small to catch, and i have found at least 100 other accounts that are of very similar if not identical infestations online with a search engine yet and yet no one seems to have a definitive awnser to what type of bug it is? Can ANYONE identify it. I know that it would be insane to think it a new undiscovered species?

equation:
tan(beta) = 2sin(beta)

so far i have...
sin(beta)/cos(beta) = 2sin(beta)/1

then cross multiply...
sin(beta)=2sin(beta)cos(beta)

now i'm stuck, what should i do next? thanks for the help.
