HELP WITH CHEMISTRY!!?

Question

so im supposed to do a project on nitrogen. i got almost everything.......but i still need.

1. source

2. abundance in earths crust

3. cost in bulk

4. cost in pure

please make it all simple .....

thanks.

Answer 1

1. source

from our atmosphere , wich is 78% nitrogen, the condense & purify liquid & gaseous nitrogen

http://en.wikipedia.org/wiki/Nitrogen

"Nitrogen occurs naturally in a number of minerals, such as saltpetre (potassium nitrate), Chile saltpetre (sodium nitrate) and sal ammoniac (ammonium chloride). Most of these are relatively uncommon, partly because of the minerals' ready solubility in water. See also Nitrate minerals and Ammonium minerals."...

====================================

2. abundance in earths crust

    20 parts per million by mass http://www.webelements.com/nitrogen/geol...

=================================

3. cost in bulk 50 cents/ liquid nitrogen gallon:

"How much does Liquid Nitrogen cost?

The process of making liquid nitrogen consists of condensing atmospheric gases (principally nitrogen and oxygen), separating the liquefied gases, packaging and handling, and delivering the liquids. The most expensive part of this process is packaging and handling. This is reflected in the relative costs for "cylinder" and "bulk" gas prices. In the US, liquid nitrogen usually costs about $2/gallon when delivered in dewars and about $.50/gallon when delivered and pumped into a bulk storage tank. Prices tend to be higher the farther away from the condensing plant you are and outside the continental United States."

if bulk gaseous nitrogen is needed, you by liquid & use the gas it evolves)

4. cost in pure

http://www.ktf-split.hr/periodni/en/n.ht...

The price of 99.999 % pure nitrogen gas costs

177.10 €/dm3 ( in small quantities (1 dm3) = $ 261.52 / litre today's rate

and about 2.05 €/dm3 in large quantities (300 dm3) = $3.03 / litre

today's exchange rate :
