Explain the primary, secondary, tertiary and quarternary structure of Hemoglobin. Also explain the function of all parts of the hemoglobin molecule. Two outside references should be used. Name these references.
A helium balloon is filled with a volume of 1.5L and has a pressure of 2.5 atm at 50oC. If it is then heated to 150oC, what will the resulting pressure be if the resulting volume is 1.6 L.
Three gases (8.00 of methane, , 18.0 of ethane, , and an unknown amount of propane, ) were added to the same 10.0- container. At 23.0 , the total pressure in the container is 4.40 . Calculate the partial pressure of each gas in the container.
