Re: AWD disable light on in Rendezvous Buick? he is talking about the AWD light only. if this is the only one, it is the oil temperature. Check your owner manual, it is inside. I got my AWD light on one time, good thing my car was on warranty, they changed the rear diff, but it was not the GM warranty.
Hydrogen bonds hold together the atoms in a water molecule. A single water molecule is made up of two hydrogen atoms and one oxygen...
The covalent bonds are therefore polar, and the oxygen atoms have a slight negative charge (from the presence extra electron share), while the hydrogens are slightly positive (from the extra un-neutralized protons). A water molecule consists of two atoms of hydrogen linked by covalent bonds to the same atom of oxygen. Atoms of oxygen are electronegative and attract the shared electrons in their covalent bonds. Consequently the electrons in the water molecule spend slightly more time around the oxygen atomic center and less time around the hydrogen atomic centers.
