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 water molecule, as a whole, has 10 protons and 10 electrons, so it is neutral. In a water molecule, the oxygen atom and hydrogen atoms share electrons in covalent bonds, but the sharing is not equal. In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
