Both carbon monoxide and oxygen bind at the same active site in hemoglobin. However, carbon monoxide binds stronger than oxygen, and thus, effectively prevents hemoglobin from transporting oxygen to cells. How is the carbon monoxide acting in this process?
A gas sample containing 1.47 mol at 25°C exerts a pressure of 401 torr. Some gas is added to the same container, and the temperature is increased to 50.°C. If the pressure increases to 800. torr,
One of the treatments for gangrene and the bends, is hyperbaric oxygenation. This occurs in a chamber in which oxygen is used at higher-than-normal pressures.
A solution is prepared by adding 80.0 mL of 0.090 M HBr to 130.0 mL of 0.50 M HI. Calculate the concentrations of all species in this solution. HBr and HI are both considered strong acids.
What is the pH of a buffer solution that is 0.15 M chloroacetic acid and 0.10 M sodium chloroacetate? Ka = 1.3x10^-3.
