According to one physicist I know, most of the time the overall charge of a molecule of water is neutral.

Water molecules consist of hydrogen molecules and oxygen molecules. Most of the negative charge comes from the oxygen molecules while the hydrogen molecules carry the positive charge.
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.
It's not an ionic compound.
Because they do not have an overall charge OR any electrons that are free to move
You are describing polar molecules, of which water is probably the most well known.
water consists of polar molecules (having partially positive and negative charges) the partially charge of one molecule attracts the opposite partially charge of other molecules (hydrogen bonding) it creates attraction among water molecules.
Because a nonpolar molecule has no overall charge, it will not interact with a positive force.
Although a water molecule has an overall neutral charge (having the same number of electrons and protons), the electrons are asymmetrically distributed, which makes the molecule polar. This polarity makes them bond together weakly.
Water molecules are attracted to sodium chloride because water is a polar charge. Slightly positive and slightly negative ends on H2O, the sodium chloride Na+ and Cl- attracts to the opposing charge on the water molecule
This question makes no sense. if you mean 'how are water molecules polar' it is because the charge between oxygen and hydrogen is not completely cancelled out.
The reason why the overall charge of a water molecule is zero is because the number of positive hydrogen ions and the number of negative hydroxide ions are equal, so they cancel each other out.
Salt disassociates in water because hydrogen molecules are slightly positive charge and pulls away the chloride ions (a negative charge ion) and the oxygen molecules are slightly negative charge and will attract the sodium ions (a positive charge ion) dissolving the sodium chloride into the water.
