Consider the titration of 30.0 mL of 0.035 M NH3 with 0.025 M HCl. Calculate the pH after the following volumes of titrant have been added.
As proteins themselves, enzymes are comprised of amino acids. The protease from the human immunodeficiency virus 1 (HIV-1) contains two aspartate (Asp) amino acid residues, referred to here as Asp-1 and Asp-2, that are essential for catalysis. The..
Calculate the pH of a buffer solution prepared by dissolving 0.20 mole of cyanic acid (HCNO) and 0.80 mole of sodium cyanate (NaCNO) in enough water to make 1.0 liter of solution. [Ka(HCNO) = 2.0 ? 10-4]
indicate whether the trailing zero in each value is significant, not significant or possibly significant
Reversible adiabatic processes are isentropic. Are isentropic processes necessarily reversible and adiabatic?
