QUESTION 1 Turn to Page 23 of your lab manual. Looking at Figure 2.5 (picture of lung), the net direction of carbon dioxide will be towards the (lung or capillary). The net direction of oxygen will be towards the (lung or capillary). process of diffusion, there is an exchange of oxygen and carbon dioxide between the alveolar sacs and the blood in the capillaries. 1. Draw a heavy arrow on figure 2.5 to indicate the net direction of carbon dioxide movement. Air in alveolar sacs of lungs 1% CO2 20% O2 Blood capillary Blood in the capillary 4% CO2 12% O2 Figure 2.5. Diffusion of oxygen and carbon dioxide. 2. Draw a dotted arrow on figure 2.5 to indicate the net direction of oxygen movement. 23 23

5.32 Cylinders of compressed gases are often labeled to show how many “SCF” or “standard cubic feet” of gas they contain. 1 SCF of gas occupies a volume of 1 ft3 at a standard temperature and pressure of 0°C and 1 atm. A particular cylinder weighs 122 lb. when empty and 155 lb. when filled with krypton gas at 26°C. How many SCF of Kr does this cylinder contain?

At 0 C and 1.00 atm, as much as 0.70 g of O2 can dissolve in 1 L of water. At 0 C and 4.00 atm, how many grams of O2 dissolve in 1 L of water?
