2. What can be concluded from this thermochemical equation?
NaOH(s) → Na*(aq) + OH(aq) AH - - 45 kJ/mol run
A Sodium and hydroxide ions have more potential energy then solid sodium hydroxide.
B The dissolving of sodium hydroxide is an endothermic process.
C The temperature of the solution would increase as sodium hydroxide dissolves
D The rate of dissolution increases as temperature is decreased

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
