Question

water has an uneven distribution of electrons. analyze the model of a water molecule.
the uneven distribution of electrons in a water molecule causes which of the following characteristics?
chemical bonds
polarity
density
cohesion

Explanation:

The uneven electron - distribution in a water molecule creates a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. This charge separation leads to polarity. Chemical bonds are the forces holding atoms together and not directly caused by uneven electron distribution in this context. Density is related to mass and volume and not a direct result of uneven electron distribution. Cohesion is the attraction between like molecules, and while polarity contributes to cohesion in water, the most direct characteristic caused by uneven electron distribution is polarity.

Answer:

B. polarity
