Discuss the ability of compound J to act as a base, supporting your answer with commentary...
discuss is your own words, is supporting versus not supporting the affordable care act (ACA) a matter of ethics?
Please help! 4. Suppose Compound B is the conjugate base of Compound A. Calculate the approximate concentration of Compound A that must be present in a 0.042 M solution of Compound B to produce a pH of 4.96. The K. for Compound A is 1.8 x 109. Show your work. Round your final answer to the nearest hundredth decimal place. (5pts) 5. Consider the structure below. Then using the empty boxes, answer parts (a)-(e). HO (a) (1 pts) Draw a...
A cysteine found in the interior of a protein can act as a base in a chemical reaction. Since the pH for living organisms is held constant near 7.3, what would have to happen to the pKa of the side chain (as a result of microenvironmental effects) to optimize cysteine’s ability to act as a base. Explain your answer.

please help in all sections asap! The following two drawings are resonance structures of one compound. a-o But the following two drawings are not resonance structures Not resonance structures They are, in fact, two different compounds. Choose the correct explanation(s). Select all that apply. Benzene does not have three C-C single bond and three C-C double bonds. In fact, all six C-C bonds of the ring have the same bond order and same length. Benzene have three C- single bond...
