A solution contains 0.036 mol L-1 Cu2+ and 0.044 mol L-1 Fe2+. A solution containing sulfide ions is added to selectively precipitate one of the metal ions from solution. At what concentration of sulfide ion will a precipitate begin to form? What is the identity of the precipitate? Ksp(CuS) = 1.3 × 10-36, Ksp(FeS) = 6.3 × 10-18.
◦ 1.4 × 10-16 mol L-1, FeS
◦ 3.6 × 10-35 mol L-1, FeS
◦ 3.6 × 10-35 mol L-1, CuS
◦ 1.4 × 10-16 mol L-1, CuS
◦ 1.4 × 10-16 mol L-1, both CuS and FeS will precipitate

A cataract is a clouding of the eyes' natural lens. As we age, some clouding of the lens may occur. The first sign of a cataract is usually blurry vision. Although glasses and other visual aids may at first help a person with cataracts, surgery may become inevitable. Cataract surgery is very successful in restoring vision, and it is the most frequently performed surgery in the United States.

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).
