Oxygen binds to the hemes in myoglobin and hemoglobin. However, when plotting oxygen's ability to bind to the protein vs. O2 concentration myoglobin and hemoglobin have dramatically different graphs. Explain this observation.
Phosphorus-32 is used in the form of Na2HPO4 in the treatment of chronic myeloid leukemia, among other things. (a) The isotope decays by beta-particle emission. Write a balanced equation for this process.
Consider the four polysaccharides amylose, spartylose tarhylose and ranylose. Amylose is the unbranched polymer of a-(1Ã 4) linked glucose molecules found in starch, while spartylose, tarhylose and a Blue Devylosea
Three gases, hydrogen, helium, and krypton are confined in a 10.0 L vessel at a pressure of 6.00 atm. The vessel contains 4.00 moles of hydrogen, 3.00 moles of helium, and 5.00 moles of krypton.
If a solution is made by mixing 20.0mL .4M NaCH3COO with 30mL .4 CH3COOH, calculate the pH for acetic acid, Ka = 1.76x10^-5.
Calculate the specific heat of a metallic element if 314 joules of heat energy are needed to raise the temperature of a 50.0 gram sample from 25 degrees celsius to 50 degrees celsius.
How much heat (in kilojoules) is evolved or absorbed in the reaction of 3.05 of with enough carbon monoxide to produce iron metal?
A buffer solution is composed of 1.360 g of KH2PO4 and 5.677 g of Na2HPO4. What is the pH of the buffer solution?
