Which of the following compounds have a nonzero dipole moment?

a) Cl2 b) GaBrH2 c) SiCl4 d) NO3-

I know (a) isn't right for sure. I don't think (d) is right either since is symmetrical. I drew out (b) and (c), but I'm doing something wrong if I'm not getting it right...Any help would be appreciated. Thanks.

Why the water of river Ganges remains sterile even after storing in a bottle for years?

My dad, during the early sixties, stored Ganges water collected from Rishikesh in a bottle to verify people's claim that it always remains pure. When examined under microscope after about two years by a Professor of chemistry who was my dad's friend, the sample was found to be completely free from any bacteria or algae. Chemical tests did not show presence of any known germicidal or toxic chemical.which could inhibit any organic growth. The Professor opined that this very qualty of Ganges gave it the status of Holy River and that some friendly virus which could not be seen by standard laboratory microscopes, may be responsible for the sterile quality of the water.

Now that technology has greatly advanced since those days, can anyone explain the actual reason?

Why is the "total charge" of Al(NO3)3 six?

Chem question! The 3's are coefficients. I don't understand why the total charge of the molecule Al(NO3)3 would be six. If someone can explain this to me it'd be really helpful.

And also, can someone tell me what (a) the balanced equation would be for the reaction between Mg(OH)2 (base) and Vinegar (acetic acid)? And (b) determine the moles of vinegar per mole of Mg(OH)2? (the 2 is a coefficient)

Thanks SO much.
