Question 1

A solution contains 0.018 moles each of I, Br, and Cl. When the solution is mixed with 200 mL of 0.24 M AgNO3, how much AgCl(s) precipitates out?
 
Ksp
AgI
 
= 1.5 × 10–16
 
Ksp
AgBr
 
= 5.0 × 10–13
 
Ksp
AgCl
 
= 1.6 × 10–10


0.0 g
1.7 g
2.6 g
3.3 g
5.0 g

Question 2

A solution is 0.010 M in each of Pb(NO3)2, Mn(NO3)2, and Zn(NO3)2. Solid NaOH is added until the pH of the solution is 8.50. Which of the following statements is true?
Salt
Ksp
Pb(OH)2
1.4 × 10–20
Mn(OH)2
2.0 × 10–13
Zn(OH)2
2.1 × 10–16


No precipitate will form.
Only Pb(OH)2 will precipitate.
Only Mn(OH)2 will precipitate.
Only Zn(OH)2 and Pb(OH)2 will precipitate.
All three hydroxides will precipitate.

Though Candida and Aspergillus species are the most common fungal pathogens causing invasive fungal disease in the immunocompromised, infections due to previously uncommon hyaline and dematiaceous filamentous fungi are occurring more often today. Rare fungal infections, once accurately diagnosed, may require surgical debridement, immunotherapy, and newer antifungals used singly or in combination with older antifungals, on a case-by-case basis.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
