Water has a polar covalent bond because the electrons that the hydrogens share with the oxygen hang out around the oxygen more than the hydrogens. This is because the oxygen has more protons in its nucleus than the hydrogen. The hydrogen become positively charged and the oxygen becomes negatively charged. Then also when the molecule becomes cold, loses energy, the hydrogens get closer to each other, but they repel each other, which is why ice is less dense than water. The hydrogen then also forms hydrogen bonds with the other water molecules, attaching to the negatively charged oxygens.

What will a molecule in which the polar covalent bonds do not cancel out be?
polar
The bonds between hydrogen and oxygen in a water molecule are classified as?
Within the molecule, the bonds are covalent bonds. Between water molecules, they're hydrogen bonds.
Is NF3 a purely covalent molecule?
The molecule is covalent, the N-F bonds are polar covalent.
Is molecule AsF3 polar?
It is a polar molecule and has polar bonds.
Is a covalent bond neutral?
Molecules can be polar or non-polar; bonds are what hold molecules together, but they are not in themselves polar or non-polar. I should point out that the most famous polar molecule in the world, the water molecule, does have covalent bonds.

Is molecule AsF3 polar?
It is a polar molecule and has polar bonds.
What types of bonds hold together a water molecule?
Water has covalent bonds.The bonds between atoms in a water molecule are covalent bond, somewhat polar ones.
A molecule in which the polar covalent bonds do not cancel out?
unsymmetrical
Is HCN nonpolar covalent bond?
This molecule contains polar covalent bonds.
What type of bonds form within a water molecule?
Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.

Name a non-polar covalent molecule having polar bonds?
carbon dioxide
Is carbon tetrafluoride a covalent or polar covalent or ionic bond?
Polar covalent bonds. Not that due to the symmetry of the molecule (tetrahedral) the bond dipoles cancel each other out and overall the molecule is non-polar.
A water molecule is held together by what kind of bond?
The water molecule itself is held together by polar covalent bonds between the oxygen atom and the two hydrogen atoms.
