In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons ... Opposite polar ends of molecules attract and hold one ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

This is due to the water expanding as it is frozen because of the hydrogen forming an open type lattice. high surface tension relatively high viscosity All ionic lattices and polar covalent ...

The sucrose molecules dissolve as they are separated from the other molecules and mix into the water. The sucrose molecule has many oxygen-hydrogen (O–H) bonds which are polar. The charge-density ...
