Calculate the rate of dissolution (dm/dt) of relatively hydrophobic drug particles with a surface area of 2.5×103 cm2 and saturation solubility of 0.35 mg/ml at 25°c in water. the diffusion coefficient is 1.75×10-7 cm2/s, and the thickness of the diffusion layer is 1.25m. the concentration of the drug in the bulk solution is 2.1×10-4 mg/ml.

Which is a difference between molecular compounds and ionic compounds? select the correct answer below: question 5 options: molecular compounds typically form between a metal and a nonmetal, while ionic compounds typically form between nonmetals. molecular compounds result from the transfer of electrons between atoms to form ions, while ionic compounds result from the sharing of electrons between neutral atoms. molecular compounds are formed of discrete, neutral molecules, while ionic compounds are formed of large repeating arrays of opposite charges. molecular compounds have high melting points and high boiling points, while ionic
