1. Calculation: Using the Henderson-Hasselbalch equation, explain mathematically why a solution is at a pH below the pKa for an acid that more than 50% of the molecules have the proton on (not off). 2. Calculation: If you have a pH of 5.5 for a weak acid with a pKa of 4.76, then is there more A- or more HA in the solution? Explain why in words using your knowledge of positive or negative log numbers.
Why is there a negative sign? can you please explain the derivation of this formula? 10:35 PM Mon Jan 20 42% 5 TODO of + + VIEUX UU VIL JULENT The utility of the endowment is US(6,2) = 6325; call this value Ū. The indifference curve US(B,C) = U. To find another point on this curve, pick any B and solve for C. E.g. let ! 3iC'} = 632 C = 8 so (3,8) also lies on the same indifference...

If one adds electrical insulation to a circular wire, which of the following would happen? a) Conduction resistance will drop b) Convection resistance will drop c) hinder transfer of heat in the wire to surroundings. d) Help the transfer of heat in the wire surroundings.
Explain why the overall sign of the molecular orbital wavefunction is not important, but the relative sign of the two atomic orbitals which are forming an molecular orbital are of significance
The table below lists the electric field at various locations along the +-axis. The negative sign means that the electric field points in the -x-direction.
