Explain why water is polar. Check all that apply. View Available Hint(s) Water is known as a polar molecule because Check all th
sineoko [7]

Answer:

The correct statements that you must check are:

  • The oxygen atom has a greater attraction for electrons than the hydrogen atom does (second statement).

  • The electrons of the covalent bond are not shared equally between the hydrogen and oxygen atoms (fourth statement).

Explanation:

Electronegativity is the relative ability of an atom to pull the electrons in a covalent bond.

Hydrogen has an electronegativity of 2.20 and oxygen has 3.44. That means that oxygen attracts the electrons more strongly than hydrogen does (second statement).

As consequence, the electrons in the covalent bond H - O of water are not shared equally (fourth statement): the electron density will  be higher around the O atoms.

Of course, this discards the statement telling that hydrogen atom attracts electrons much more strongly than the oxygen atom, and the statement telling that hydrogen and oxigen have same electronegativity.

Such difference in electron densities creates a dipole moment, so you discard the last statement (that the water dipole moment is equal to zero).

Which Locations are likely to have subatomic particles with the GREATEST mass?
wlad13 [49]

2 and 3, because there are the protons and neutrons which have a greater mass than the electrons which are found in the locations 1 and 4.

Explanation:

The atom contains a nucleus, which is made from protons and neutrons, and electrons which are found around the nucleus.

The mass of the atoms is concentrated in the very tiny space represented by the nucleus. Of course the electrons have a mass too, but is very small compared to the protons and neutrons, and we usually neglect its mass.
