Question 1

What is the molarity of a potassium triiodide solution, KI3(aq), if 30.00 mL of the solution is required to completely react with 25.00 mL of a 0.200 mol L-1 thiosulfate solution, K2S2O3(aq)? The chemical equation for the reaction is

2S2O32-(aq) + I3-(aq) → S4O62-(aq) + 3I-(aq)

◦ 0.120 mol L-1
◦ 0.333 mol L-1
◦ 0.0833 mol L-1
◦ 0.167 mol L-1

Question 2

Based on the balanced chemical equation shown below, determine the molarity of a solution containing Fe2+(aq) if 40.00 mL of the Fe2+(aq) solution is required to completely react with 30.00 mL of a 0.250 mol L-1 potassium bromate, KBrO3(aq), solution. The chemical equation for the reaction is
 
6Fe2+(aq) + BrO3-(aq) + 6H+(aq) → 6Fe3+(aq) + Br-(aq) + 3H2O(l)

◦ 1.12 mol L-1
◦ 0.0312 mol L-1
◦ 0.188 mol L-1
◦ 2.00 mol L-1

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.
