What is the function of 2,3-bisphosphoglycerate (BPG)? Why do red blood cells have large amounts of BPG?
Briefly explain why it is important to allow a hot sample to cool to room temperature before you determine its mass.
Explain which of the following molecules is more likely to exist: S3+, I3+ and P3. Depict the structure of the most likely candidate(s)
Identify the chiral centers with asterisks and label each center as R or S. 5. How might you use 13C NMR spectroscopy to determine if the brominated product is contaminated with some unreacted starting material (during the bromination of trans-cin..
Consider the 1H19F molecule. The bond length of 1H19F is 91.7 pm. The wavenumber of light associated with a transition from the ground vibrational state to the first excited state is 1159.18 cm^-1.
Draw a reaction profile to illustrate the conversion of 2-methyl-2-butanol and HCl to 2-cloro-2-methylbutane and water. Label enthalpy of activation, H‡, for the rate-determining step and the enthalpy, Hrxn, for the overall reaction.
The flue gases after that pass through a heat exchanger from which they emerge at 50°C. Per mole of methane, explain how much heat is lost from the furnace and how much heat is transferred in the heat exchanger
If 200. mL of aqueous 0.862 M HCl is mixed with 200. mL of aqueous 0.431 M Ba(OH)2 in a constant-pressure calorimeter of negligible heat capacity.
