The bond between two eatoms of the same element in which the electrons are equally shared is known as a nonpolar covalent bond. in a water molecule,

I'm assuming you are supposed to complete the given statement? In a water molecule, the bonds between the hydrogen and oxygen atoms are polar covalent bonds, where electrons are unequally shared. (Oxygen is significantly more electronegative and holds onto the electrons for most of the time)

Hno3(aq) → h+(aq) + no3−(aq). picture ii best represents the strong acid hno3. strong acids are strong electrolytes
