i was wondering if you could obtain sodium (not salt but pure sodium) in large quantities (as in 4+ lbs of it) from a company without being a teacher or in some industry that requires it or is there a way to isolate if from some other substance and get it (as in take the chlorine out of salt). Lithium and potassium would work too if there was a way to get either of them.

I have a thoery of dark matter, and intelligent of many answers of a lot of Ghost or spirit sightings, i believe dark matter excists in the earths atomosphere.
Black hole example it can consume thousands of planets.
when consumed nobody at the present day can say where these planets go?
within the consumption of the planets dark matter is the Most of the black hole?
Correct me if i am wrong????
So when the black hole consumes, when earth was formed. Dark matter was in the mix.
Dark matter is nothing, no atoms just black nothing.
But has wieght............ A teaspoon of it would not be able to pick up.
Is this true about the weight? and what do you think of my thoery

C1/P1 = C2/P2

If I want to find P2, what would the new formula be? How do you isolate P2?



what is the rule? and does this rule apply to P1 also since they're both in the denominator?

2006-09-01 14:19:54 · 3 answers · asked by Anonymous in Chemistry

or if you believe in both that's fine too. give reasons.
