Pyrene is an organic poly cyclic aromatic compound and SDS is a sodium salt of sulphate (a type of detergent). As you know detergent is unable to form micelles in hard water, the same concept is applied here. Large concentrations are required to make CMC. On the other hand RL is a solution of sodium lactate it also contain CaCl2, NaCl and KCl. Ca2+ in makes Micelles easily than reactive metals therefore it require less concentration.
Why is the concentration of pyrene used to determine CMC for SDS so much greater than...
Why is the pka value of cycloheptatriene so much greater than that of cyclopentadiene? Where pka value of cycloheptatriene =36, Pka value of cyclopentadiene=17
Assume that the concentration of the ligand is much greater than the concentration of the protein. When ligand Y is present at a concentration of 2 x 10-6 M, 50% of the binding sites on the molecules of protein X are found to be occupied. If the concentration of the ligand is increased to 3 x 10-6 M, what fraction of the binding sites will be occupied? Please explain the steps to solve this problem.
Is drug concentration in plasma higher than in the serum? If so, why?
Why is RNA capable of assuming a much greater variety of structure than DNA? (4 marks)
Rb : [kr] Rb++[Ar]4323d104p) b Why is the second ionization energy much greater than the first? Second ionization energy is always 4 times greater than the first. After removal of the second electron, rubidium has a configuration of noble gas. The second electron is removed from 4p, which is much closer to the nucleus than 58, Rb has a configuration of noble gas, which is stable. Submit What experiments could be done to provide some evidence that the correct formulation...
6.) Explain with as much detail possible why when bonding, fluorine will have a greater pull on bonding electrons compared to iodine. U 7.) Explain with as much detail possible why sodium has a larger atomic radius than magnesium, 8.) Explain with as much detail possible why phosphorus has a larger atomic radius than nitrogen. 9.) Elements are very chemically reactive in groups 1 and 7. Use the trends to explain this observation. 10.) Below are the first thru third...
