Homework Answers
The air contain different type of the gases like Nitrogen ,Oxygen,carbon di oxided ,carbon monoxide ,sulpher di oxide ,smog and other several gases .In which the most abundant gas in the air is Nitrogen (about 78%).The second abundant gas is oxygen ,with which we can breath (about 20.95%).And the third abundant gas is Argon (about 0.9%).The forth abundant gas is carbon dioxide (about 0.04%).
so The third abundant gas in the air mixture is argon
so the correct option is B.
Add Answer to:
"The air that we breathe is actually a mixture of several gases. Of those involved, which is the third most abundan...

28. Which of these statements about greenhouse gases and the greenhouse effect is not correct? I. Greenhouse gases prevent infrared radiation from escaping through the atmosphere. II. To absorb infrared radiation, a molecule must have a vibration that produces a change in the dipole moment of the molecule. III. Argon is the third most abundant species in the atmosphere (after nitrogen and oxygen), and therefore is a significant greenhouse gas. IV. The average amount of carbon dioxide in the atmosphere...

Almost all gaseous systems that we use are gas mixtures, air is the most obvious example. Air is composed of 78% nitrogen, 20% oxygen, 1 % argon, 1% water vapor, 0.3% carbon dioxide. Chemists often express the composition of a gas not with percent, but with a fraction. The mole fraction of nitrogen,ΧN2 , in air is defined as ΧN2= nN2 ⁄ nTotal = 0.78 The pressure of a gas mixture is the sum of the partial pressures of each...

In a mixture of gases, how is the total pressure determined? How is the partial pressure of a gas in a mixture calculated? Determine the total pressure of a gas mixture that contains oxygen, nitrogen, and helium. The partial pressures are: Pax =20.0 kPa, Pz = 46.7 kPa, and P.. = 26.7 kPa. A gas mixture containing oxygen, nitrogen, and carbon dioxide has a total pressure of 32.9 kPa. If Po6.6 kPa and P2 = 23.0 kPa, what is Poz?...

Name Dalton's Law of Partial Pressures - Many gas samples are a mixture of gases. For example, air is a mixture of gases. The gases dissolved in blood make up a mixture as well. In a gas mixture, each gas exerts its partial pressure (the specific pressure contribution of the gas to the total pressure of the gas mixture). Dalton's law states that the total pressure of a gas mixture (Pita) is the sum of the partial pressures of the...
