Why is nitrogen gas more than oxygen gas in the air?
oxygen is used by human and animals for respiration bt nitrogen do not. for consuming nitrogen plants need nitrogen fixation ths occurs on low scale on other hand oxygen is directly used so its cunsumbtion is more then nitrogen. another important point is that oxygen is used in burning, formation of water etc ths means ratio of cunsumbtion of oxygen is mor then nitrogen
Process of converting nitrogen gas into ammonia?
Is known as nitrogen fixation, done with the enzyme nitrogenase found in nitrogen fixing bacteria.
What is Lord William Thomson Kelvin famous for?
Kelvin invented the Kelvin absolute temperature scale and told us that the atmosphere was 70% nitrogen
Why is acetonitrile more polar Why not methanol.O is more electro-ve. my guess is that nitrogen is in the end in the molecule whereas in methanol oxygen has hydrogen on one hand and carbon on another?
In Acetonitrile carbon (EN-value on Pauling's scale is 2.5) of cyanide is attached with Nitrogen(EN-value on Pauling's scale is 3.0), so , Nitrogen atom with combination of carbon, that is more EN than Hydrogen(EN-value on Pauling's scale is 2.1) attached with oxygen atom (EN-value on Pauling's scale is 3.5) in methanol, becomes more Electron withdrawing effect than -OH group in methanol. In this way -CN is more dispersive than that of -OH.
Your consultants are asking you to pass nitrogen through copper pipes while brazing to prevent oxidation inside the pipes. These pipes are for refrigerant. Is this a regular practice?
AnswerPumping nitrogen through refrigerant piping during brazing is an excellent practice. The reason is that nitrogen helps to prevent the buildup of oxide scale on the inside of the pipes during the brazing process. Refrigerant is a natural cleaning agent, and as it is being pumped through the pipes it will pick up the scale and contaminate the refrigerant. It is possible that this will damage to the compressor.

What is the electronegativity for helium?
The first scale of electronegativity was developed by Linus Pauling and on his scale helium has a value of no data on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine)
