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.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
