what are the chemical and physcial propeties of Nitrogen? can any one help!! please?!?

Question

i went to two diff sites and theyr telling me something that it in both sections its so stupid. i know i may be looking at the wrong sites but none of the sites blandly explain each.................please if you can provide something.....do it without stupid remarks........thnx :)

Answer 1

Remember the defintions of "chemical" and "physical" properties!

Physical are those that can be experienced by the senses (sight, smell, taste, hearing, touch). Chemical are those in which the chemical reaction creates a new material; however, it has become accepted practice to use "chemical property" to define a material's behavior at a set of known conditions (temperature, humidty, pressure, etc).

The site given lists just about everything you'd want to know about Nitrogen; from it, you should be able to answer some of the basic "physical" characteristics and pull what you need for the chemical ones.

Like I've answered before - since the definition of "chemical" has evolved over the years, you need to decide for yourself which ones best answer your query.

Answer 2

Nitrogen is diatomic, N2 It is a clear colorless gas at room temperature and can be separated from the air by fractional distillation. It is about 79% of the air. It does not support combustion. It is not very reactive. It is needed for life and is found in proteins.There is a nitrogen cycle.Important compounds: NH3 (ammonia),nitrates which are used to preserve meats, dissolving of N2 in the blood by divers is called the Bends,it takes 3 electrons in forming compounds, N--- or N with a -3, The N2 is a covalent bond, sharing 3 pairs of electrons.Legumes are plants that are able to take nitrogen from the air. lightning can also form nitrogen compounds from the air. Plants need nitrogen in fertilizer.

Answer 3

Not sure what are stupid remarks...
you didnt say what purpose of the question. In general some physical properties of N2 = clear, odorless colorless gas with molecular weight of 28 g/mol.so it is relatively heavy. nitrogen constitute some 70% of our atmosphere.
It,s most important chemical property: it is inert, meaning it does not react easily with other compounds. Nitrogen is used in chemical synthesis as inexpensive inert environment when handling highly reactive substances.
Liquid nitrogen is used to bring chemical reaction to VERY cold temperatures.

Answer 4

physical properties:colourless,odourless and tasteless gas.2)pure nitrogen is slightlt lighter than air.3)slightly soluble in water,4)melting point of -210'c and a boiling of -196'c.these low temp are due to the weak van der waals forces that exist between nitrogen molecules in solid and liquid states.

chemical properties:1) nitrogen gas exist as a diatomis molecule with tripple covalent bond between it's atoms.(N_=N).teh high bomd energy of the tripple bond(946KJ-1)makes the bond very stable and accounts for the unreactive nature of nitrogen under ordinary conditions.2)it combines directly with very electropositive metals e.g Mg,Ca,Al and Fe to form nitrides.
Mg+N2------>Mg3N2
3)it also combines reversibly with hrdrogen to form ammonia.and with oxygen at a very high temperature(about 2000'c)or in the presence of high voltage electric spark to form small amounts of nitrogen(II)oxide.in nature this reaction occurs when lightning flashes
N2+O2---->NO2

Answer 5

well nitrogen itself, is found within nature as N2, nitrogen gas. it makes up about 71% of the air we breath. it is non flammable.

Answer 6

forms n2. a gas.
