There are so many environmental things that can kill a virus yet we have yet to find a way to use this to our advantage. Oxygen kills virus's. Why not slowly oxygenate our body piece by piece and see if that works?

This question has been bugging me for a while now. If anyone can truthfully answer. Naturally, this is a hypothetical question, so ignore things like pregnancy and birth complications.

I am working on a science fair experiment, and my teacher offered to create a solution for me. I went in, and she was too busy to help so now I am on my own. I went and bought 28% hydrochloric acid but I need to dilute it to 0.1 M, does anyone know how much water Iand how much acid it will take to dilute it to 0.1 M? (How many grams of acid mixed with how many mL of water to get it diluted).

I was answered this before:
"Hydrochloric acid is anywhere from 28% to 36% HCl, so you'll have to dilute it by roughly 1:60 to get a solution that is an acceptable simulation of gastric juice for your purposes."

But, what does 1:60 mean?

Why is it that precipitation under 32 degrees is sometimes light fluffy snow and sometimes crappy cold sleet/freezing rain? What atmospheric differences exist to deterine what form the precipitation will take? And how does hail fit in? Becase hail falls at temps much above 32 degrees sometimes.

A friend found it on a job site, here in central Oregon. I collect rocks, but this is the first one I have seen like it. I tried several websites that identify rocks and minerals, but they were no help .http://img208.imageshack.us/img208/9789/hpim0532editedrg9.jpg
