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 formula H20 tells us that one molecule of water is comprised of 2 atoms of hydrogen and one atom of oxygen bonded together. The bonds which hold the hydrogen and oxygen together are called covalent bonds - they are very strong. Let's look at a picture of a molecule of water: In this picture the two hydrogens are represented by white spheres and the oxygen by a red sphere.
