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 slight positive charge of the Hydrogen in one water molecule is attracted to the slight negative charge of the Oxygen atom in another molecule.    Ionic bonds, covalent bonds, and hydrogen bonds are 3 completely different methods of molecular interaction. Ionic bonds exist in compounds, for example, such as salts: HCL, NaCl. Unlike covalent bonds, Ionic bonds do not form an actual bond by the sharing of electrons between the 2 different atoms. Instead, similar to hydrogen bonding, they are held together by opposite charges in each atom that composes the molecue.
