0.375 g of a monoprotic acid (mm = 245 g/mol) is dissolved in water to produce 25.0 mL of a solution with pH = 3.28. Determine the ionization constant of the acid.
Draw graphs representing Boyle's law, Charles's law, and Gay-Lussac's law for a fixed amount of gas. Make sure that you label each axis and state the assumptions for each law-that is, the variable(s) that is (are) held constant for each law.
a.) Can you be certain that the organic layer would from the upper layer? Eplain in details. b.) How could you test to determine which is the non aqueous layer? Explain in details.
The entatic state theorem proposes that enzymes create at the active site an area with its energy closer to that of a unimolecular transition state, rather than that corresponding to a conventional, limiting form of the molecule
