Yes. Taking water, H2O, one Oxygen atom bonded to two Hydrogen atom as example) is not symmetrical( In 3-dimentions). Oxygen which is an electronegative element tends to pull electron from the Hydrogen-Oxygen bond and thus becoming a negative dipole living hydrogen as a positive dipole. so water molecule is a polar molecule. This is why when you bring a comb you just used near a slim stream of water, the stream bends toward the comb.

What is a factor that determines whether molecule can cross a cell membrane?
size/ polarity can be the factors
What determines whether a solute is hydropholic or hydrophobic?
What determines a molecule's solubility degree in water is its polarity. Equals dissolve.
Any molecule that has a polar geometry is called what?
A good clue is to look at the symmetry of the molecular geometry. Molecules that are not symmetric are polar.In a bond, the more electronegative atom attracts a bigger share of the shared electrons than the other. This separation of charge results in a bond dipole. When all the bond dipoles of a molecule are added, the net dipole is called the permanent dipole moment. When the bond dipoles cancel, the molecule's dipole moment is zero and the molecule is called nonpolar. If the bond dipoles do not cancel, the molecule is polar.Lone pairs contribute to the polarity of a molecule. Since there is no positive nucleus to offset the negative charge of the lone pair, the end with the lone pair will always have a higher partial negative charge than any atom.The key to determining whether or not dipoles cancel is to consider their direction as well as their magnitude. The direction is determined by the molecular geometry. The Lewis structure does not represent the molecular geometry.
What three factors affect solubility make sure to include the differences in solids liquids and gases?
1. Polarity 2. Molecular mass 3. Whether or not the molecule is branched.
What factor other than electronegativity determines whether a molecule as a whole is polar or not?
The shape of the molecule is a big indicator. If the molecule looks like it has some symmetry to its shape, and its poles are directly opposite of each other, then there it`s a good bet that it`s non polar.

What determines whether or not a substance will dissolve?
The most important characteristic is the polarity of the solvent and solute.
What determines whether a compound is a polar compound?
A number of factors. The polarity of the chemical bonds due to differences in electronegativity. The geometry of the moecule which may lead to these bond dipoles cancelling each other out. The contribution of a lone pair.
What property determines whether an atom forms an ionic polar covelant or nonpolar covelant bond?
You have to now the VSERP theory. The number of valence electrons determine the polarity of the molecule as well of the electronegativities of the elements involved. The less symmetric the molecule the more polar it is.

How does the shape of a a molecule affect the polarity of the molecule?
The shape of a molecule affects polarity because of how bond dipoles between two atoms is affected by other atoms in the molecule. Bond dipoles are vector quantities (which means they have magnitude and direction), so when a molecule has two or more bond dipoles they can cancel each other out if they perfectly oppose each other. For example CO2 (O=C=O) has two dipole bonds, but since they equaly oppose each other they cancel out and the molecule is nonpolar. In bent molecules like H2O, the two hydrogens bonded to the oxygen have equal dipole moments, but they do not directly oppose each other so they do not cancel out. As a result the molecule is polar. So in summery the molecule's geometry affects the polarity of the molecule by dictating the direction of the vector quantities of the dipole bonds, which determines whether they will be able to cancel each other out (nonpolar) or allow for non zero dipole moments (polar).

What determines whether charges attract or repel?
If charges are alike, they repel. If charges are opposite, they attract.
What determines whether a compound will dissolve in whether?
The polarity or charges of compounds will determine if a compound would dissolve in water, where compounds with opposite charges within their molecules dissolve in water.
What determines whether polarity of a welding machine is set up for DCEN or DCEP?
The electrode. In some cases thin materials weld better with DCEN.
