MODEL 3: PARTIAL PRESSURE Dry air is 78% nitrogen, 21% oxygen, and 1% argon. A percentage is a ratio: "78%" means that out of 100 particles 78 will be nitrogen, or 0.78 as a fraction. Such fractions are unitless. CRITICAL THINKING QUESTIONS 15. Approximately what is the pressure in the room where you are working? (Include the units.) 16.

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...

Henry’s law states that the solubility of a gas is directly proportional to the partial pressure of the gas if the temperature is constant. Hyperbaric chambers, which provide high pressures (up to 6 atm) of either air or pure oxygen, are used to treat a variety of conditions, ranging from decompression sickness in deep-sea divers to carbon monoxide poisoning. Look up the Henry’s Law Constant (kH) for N2, O2, and CO2 in the textbook. a) Calculate the solubility (concentration in...

Define partial pressure. What is the partial pressure of oxygen (PO2) in the outside air, in the alveoli, in the pulmonary vein, and after the tissue (i.e. muscle)? What is the cause of the drop on PO2 at each of these places? What is the partial pressure of CO2 (PCO2) in the arterial blood after an exhalation and then after the muscles? What causes the PCO2 to go up from the lungs to after the muscles?

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...
