The description which accurately represents a water molecule is slightly negative oxygen pole, slightly positive hydrogen poles.

Water is a polar molecule. This means that the molecule has a dipole moment.

The polarity of water arises from the difference in electronegativity between hydrogen and oxygen.

Hence, in water molecule, oxygen is slightly negative and hydrogen is slightly positive thereby resulting in a dipole.

Calculate the amount of heat in kilojoules required to vaporize 2.58 kg of water at its boiling point.

givi [52]

Answer:

The amount of heat required to vaporize 2.58 kg of water at its boiling point is 5,830.8 kJ.

Explanation:

A substance undergoes a change in temperature when it absorbs or gives up heat to the environment around it. However, when a substance changes phase it absorbs or gives up heat without causing a change in temperature. The heat Q that is necessary for a mass m of a certain substance to change phase is equal to:

Q = m*L

where L is called the latent heat of the substance.

In this case:
