Answer: Option C

Explanation:

The nitrogen cycle can be defined as the process by which the nitrogen is being recycled. The nitrogen is transferred from the atmosphere to the plants and then from plants to animals, human beings.

Then from animals and human beings it is again transferred into the soil and then atmosphere.

The nitrogen that is found in the sol is not in the usable form by the plants, nitrogen fixing bacteria converts it into usable form.

Select the correct answer. Which statement correctly explains the polarity of the water molecule? A. The hydrogen end of the mol
Nuetrik [128]

Answer:

option B) The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge.

Justification:

The electronegativity of an element accounts for its relative ability to attract electrons.

Being oxygen more electronegative than hdyrogen (the electronegativity of oxygen is 3.44 while the electronegativity of the hydrogen is 2.20), the electron density will be displaced toward the oxygen, letting it with a partial negative charge and the hydrogen with a partial positive charge.

Finally, since the charge is not symmetrical distributed around a center of the molecule, the molecule ends being polar.
