A polar molecule
Yes, this is why a polar substance will create a stable solution with another polar substance, such as starch into water. A non-polar molecule such as oil will however not be …attracted to water and therefore not form a stable solution. By stable solution I mean (basically) that if you mix the two together that it will stay that way.
because there is an uneven distribution of electrons between the oxgen and hydrogen atoms
Polar molecules have either a positive or negative charge, positives attract negatives so they will attract eachother.
An example of evidence that water molecules are polar is the fact that a thin stream of water is repeled by by a charged rod P.S i did not see any suggested answers which is …implied by the 'which of these'
A polar molecule has a partial positive charge at one end and a partial positive charge at the other. The partially positive end of one molecule attracts the partially negativ…e end of another, and vice versa, as opposite charges attract. This works in a very similar manner to how the opposite poles for magnets attract one another.
Dissolving is just when water bonds and separates the cation and anion. Water's polarity is the reason why it surrounds each ion and separates it from the oppositely charged …ion thus dissolving it. The negative end of the water surround the positive ion and the positively charged end of water surround the negative ion. If there is a polar molecule it will bond in a network with the polar water molecules This is why water will not dissolve non-polar molecules because the polarity has no affect on a non-polar molecule.
Different elements have different electro-negativities. Electro-negativity is the ability of an atom to withdraw 'electron density' towards itself, i.e. it makes electrons com…e closer to it. Fluorine is the most electronegative of the elements. Oxygen is more electronegative than hydrogen and so in water (H2O) the oxygen 'pulls' the electrons closer to itself and become slightly negative, and the hydrogen's slightly positive, this is called a permanent dipole. Due to this effect water has many properties that make it unusual and important to living things.
Since oxygen is more electronegative than hydrogen, you get something called a "dipole moment," making the oxygen slightly negative because of the unequal sharing of electrons…. This makes the hydrogen slightly positive since the oxygen atom is more electronegative (I like to think of it as being "hungry for electrons"); the electrons spend more time orbiting the oxygen than they do the hydrogens. Therefore the oxygen is slightly (or delta) negative and the hydrogen, since the electrons spend less time in orbit around the hydrogen, is delta (slightly) positive since an electron has a negative charge. O-H bonds are polar because O and H have different electronegativity values. The vector sum of the two bond dipoles is nonzero. (That is, they are not pointing in exact opposite directions.)
Water attracts polar molecules and repels non-polar molecules because water has polar molecules. Water does have a net dipole though it doesn't have net charge.
Water has hydrogen bonding , high specific heat , polar , dissolves all polar and ionic compounds due to polarity .
The opposite poles pull on each other like a magnet, the negatively charged sides attracted to the positively charged sides and vice versa
