1. A weak acid, HA, has a pKa of 4.11. a) At pH 7.11, what will the ratio of conjugate base to acid be? (Henderson-Hasselbach equation: pH=pKa + log [A-]/[HA]) b) Based on answer to "a," is there more HA or A- at that pH? c) At pH 2.11, what will the ratio of conjugate base to acid be? d) Based on answer to "c," is there more HA or A- at that pH? e) At pH 4.11, what will the ratio of conjugate base to acid be? f) Fill in the blank: if pH is greater than the pKa of a weak acid, there w...

thermodynamic mixture the more stable isomer will be the most most favorable (will be of larger percentage in the product) energy stored by capacitors constant deceleration means that the velocity over time will decrease linearly with time linearly decreasing decelerating force means that velocity over time will exponentially decrease with time The relative thermodynamic stability of isomeric organic compounds can be inferred from which of the following types of ex...

If the pka of a weak acid is 2.5, at which pH will this drug become more ionized? A. pH 5 B. pH 2.5 C. pH 1.5 D. pH 1 A. For a weak acid, a higher pH increases ionization Which equation describes the rate of drug dissolution from a tablet? A. Fick's Law B. Henderson-Hasselbalch equation C. Michaelis-Menten equation D. Noyes-Whitney equation D. The Noyes-Whitney equation describes the rate of drug dissolution from a tablet. Fick's first law of diffusion is similar to the Noyes-Wh...

AMCA FL 2 Chem Phys questions and answers 2023/2024 What atom is the site of covalent attachment of AMC to the model tetrapeptide used in the studies? A. I B. II C. III D. IV - correct answer A. I basically, asking where does the bond between amc and Y break. since you know they are attached by a peptide bond, which means the peptide chain attaches to the amino group of the next amino acid(that’s why an amino acid runs from the N-terminal to the C-terminal), the covalent attachment...
