gases like Argon Helium Methane etc are present in dash amount in the air
Answers
Answer:
The correct word to fill up the dash will be Trace.
Explanation:
Argon Helium is the Nobel gases of the atmosphere that doesn’t react with many other gases and does react at all in normal conditions of temperature and pressure. So, they are present in the atmosphere in very minute quantities. The amount of argon in the atmosphere is "0.934-mole percent". And the amount of helium in the atmosphere is "0.000524-mole percent".
Methane, on other hand, is produced from dead and decaying organic matters mainly in damp lakes and lands. The percentage of Methane thus varies from place to place. On average it is present in the atmosphere as 0.00017-mole percent.
The total concentration in atmosphere is around 1 percent.
Explanation:
Argon concentration is .93%,whereas Neon concentration is .001 percentage and Helium and Methane concentrations are .0005 ,.0001 percentages respectively .Oxygen and nitrogen have large concentrations in atmosphere.
They are present in concentrations of 20.95 and 78 percentages respectively. Helium ,Argon and Neon come under noble gases. Noble gases are colorless and odorless gases, but methane does not come under these noble gases. Noble gasses are also known as inert gases.
