Explain what is the maximum mole percent of N2 in an air mixture that could be used by divers at depths up to 85 m below sea level without undue risk of nitrogen narcosis
How does the structures of glutamine and glutamate differ? Is it because glutamine has a -NH2 side chain and glutamate has an oxygen side chain
Sketch a series of titration curves for the titration of a strong acid with a strong base where the concentration of the acid is 10-1, 10-2, and 10-3 mol dm-3 respectively. Explain why the choice of indicators is restricted at different acid conce..
What is the pH of the resulting solution? - Histidine has ionizable groups with pKa values of 1.8, 6.0, and 9.2. A biochemist makes up 100 mL of a 0.100 M solution of histidine at a pH of 5.40. She then adds 40 mL of 0.10 M HCl.
