Why is co2 polar? Or why is it polar? When i did the lewis dot structure or something, it seems pretty symmetrical to me.
But, my teqacher told me to determine polarity and non polarity by finding the difference of the electronegativity.
with 0 to .4 ...

However, since thie molecule has two electron groupsOk, the thing....
So, the bonds are polar.
Differenc
But, CO2 isn't a polar MOLECULE due to the symetricval shape of the molecule canceling out any of 0.89 in either bond.

So far, we have:
A. An aether wave created by the carbon-60 molecule displacing the
aether as it heads towards the slits.

I'm asking you what you think will happen.

How does interference occur if the carbon-60 molecule exits a single
slit and nothing."
It's a thought experiment.

An absorbing surface, which absorbs a linearly polarized photon,
receives energy (h\nu), but receives no angular momentum. Is it true?

The bond gets weaker.
The bond of the adsorbed molecule gets donated to the metallic surface's conduction band.
Electron density of the adsorbed molecule gets donated to the metallic surface's conduction band.

1.) I can understand why highly inert gases like N 2 and He are used as carrier gases in GC but why is H 2 used? Is H 2 unreactive in the absence of oxygen or something?
2.) In my lecture notes, it states that when using a non polar capillary GC stationary...

I have problem with 8 & 16.
Also 4 & 6 are wrong.
For 8 I'll give you that you can burn or oxidise glucose .
Needs understanding, no use we tell you the answers.
Then look also at 5, 14, 15.
The most serious mistake is 17.

CF4 is best described as having? 1. non-polar bonds and a net dipole moment
2.polar bond and a net dipole moment
3.polar bonds and no net dipole moment

Answer Snippets (Read the full thread at yahoo):
The molecule is nonpolar
The answer is 3.
However, the bonds are completely symmetrically arranged, so the polarity vectors add to zero.
F is more electronegative than C, so the bond is polar.
