So the question, of why one ligand binds more strongly than the other, pertains to the idea that in a system, ligand B will have a higher concentration of bound vs unbound proteins compared to ligand A at the half saturation level? Edit: To your previous statement, I did answer my own question...

From a biochemical context, considering the following two dissociation reactions and their respective dissociation constants for a protein-ligand complex: P*A + B ⇔ P + A + B, this contains the a dissociation constant called Ka = 4 x 10^-3 M P*B + A ⇔ P + A + B, this contains the a...

Homework Statement Both (E)- and (Z)-2-chlorobutenedioic acids dehyrochlorinate to give acetylene dicarboxylic acid. This reaction proceeds through the addition of a base and an E2 elimination. The (Z) acid reacts about 50 times faster than the (E) acid. Explain why. 2. The attempt at a...

Homework Statement Given the structure of Alantolactone, find two functional groups. 2. The attempt at a solution This was a question that was on my exam recently. I answered Ester and Ether, however Ether was marked incorrect. Instead, only the answers Ester and Alkene were accepted. How is...

Thanks for justifying my answer. Now on a side note, if TPP was to react with copper (II) acetate with the following formula: TPP + Cu(CH_{3}COO)_{2} \leftrightarrow 2(CH_{3}COOH) + \left[Cu^{2+}\right]\left[TPP^{2-}\right] TPP will have its N-H bond, inside the ring, to break, releasing...

Homework Statement What is its polarity of a molecule of Tetraphenylporphyrin (TPP) as a whole? 2. The attempt at a solution Given the structure of TPP, there is a ring inside that contains two N-H bonds across from each other and two nitrogen atoms with lone pairs across from each other...

This isn't a homework problem, but rather a question that I thought about. Given a Formaldehyde CH_{2}O molecule, what would the hybridization of the oxygen atom be? I know that the hybridization of the carbon atom would be: C = \frac{\uparrow}{2sp^{2}} \frac{\uparrow}{2sp^{2}}...

Homework Statement Why is the electron configuration of neutral Platinum: Pt = [Xe]4f ^{14} 5d ^{9} 6s ^{1} and not?: Pt = [Xe]4f ^{14} 5d ^{10} 6s ^{0} I thought that if the two electrons from the 6s sub-shell were to move to the 5d sub-shell, then 5d sub-shell would be fully...

Homework Statement What is the electron configuration for Ti+2? The answer to this question, from my homework, is [Ar]3d2, but I am not able to figure out why. 2. The attempt at a solution I originally thought the configuration was: Ti+2 = [Ar]4s2 and not: Ti+2 = [Ar]3d2 My reasoning was...

What do you mean?

Homework Statement You are given a battery of 220 V and a radio device that requires 1600 W to run. You are also given four resistors: three 3 Ω resistors and one 20 Ω resistor. What circuit configuration will allow the radio device to run without getting fried? The Attempt at a Solution...

Um all I can figure out is that the solids are within a closed vessel and that the temperature also appears to be 2600 K since 21.6kJ/8.314 = 2600. The only issue regarding the solid is that I don't know what the volume is, which is prohibiting me from finding the concentration mol/L. The...

Q=\frac{(pB)^4*[C]}{[B_{4}C]}

Homework Statement Calculate the cell potential at 25°C for the cell: Fe (s) | (Fe^2+ (0.100 M) || Pd^2+ (1.0*10^-5 M) | Pd (s) given that the standard potential for Fe^2+/Fe is -0.45 V and for Pd^2+/Pd is +0.95 V. A. +1.28 V B. +1.16 V C. +1.52 V D. +1.68 V Homework Equations E Cell...

Homework Statement At 2600 K, ΔG° = 775 kJ for the vaporization of boron carbide: B_{4}C (s) ⇔ 4 B (g) + C (s) Find ΔG and determine if the process is spontaneous if the reaction vessel contains 4.00 mol of B_{4}C (s), 0.400 mol of C (s), and B (g) at a partial pressure of 1.0 x 10^-5...
