Which of the following is an example of a neutralization reaction?
hcl (aq) + naoh (aq) --> h2o (l) + nacl (aq)
mg (s) + 2h2o (l) --> mg(oh)2 (aq) + h2 (g)
h2co3 (aq) --> h2o (l) + co2 (g)
pb(no3)2 (s) + 2nai (aq) --> pbi2 (s) + 2nano3 (aq)

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".
