Water molecules are polar, with the select one:
a. oxygen side being slightly positive and the hydrogen side being slightly negative.
b. oxygen side being slightly negative and the hydrogen side being slightly positive.
c. oxygen and hydrogen sides being slightly negative.
d. oxygen and hydrogen sides being slightly positive.

b. oxygen side being slightly negative and the hydrogen side being slightly positive.

Explanation:

The water molecule is a polar molecule, that is to say that its distribution of electronic density is different throughout the molecule.

In this way, in the water molecule there is a negative partial charge towards the oxygen atom and a positive partial charge towards the hydrogen atom.

This polar characteristic of the water molecule allows ions and other molecules to exhibit water solubility and is widely used in chemical reactions.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
