Section 8.2 Questions A student wants to precipitate all the toxic lead(II) ions
from 2.0 L of solution containing 0.34 mol/L Pb(NO3)2(aq).
The purpose of this reaction is to make the filtrate solution
nontoxic. If the student intends to precipitate lead (11)
sulfate, suggest an appropriate solute, and calculate the
minimum required mass of this solute.

i would say b

explanation:

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".
