Question 1

According to the following reaction, how much energy is evolved during the reaction of 32.5 g B2H6 and 72.5 g Cl2? The molar mass of B2H6 is 27.67 g mol-1.

B2H6(g) + 6Cl2(g) → 2BCl3(g) + 6HCl(g)DrH° = -1396 kJ

◦ 429 kJ
◦ 1430 kJ
◦ 3070 kJ
◦ 1640 kJ
◦ 238 kJ

Question 2

According to the following reaction, how much energy is evolved during the reaction of 2.50 L B2H6 and 5.65 L Cl2 (both gases are initially at STP)? The molar mass of B2H6 is 27.67 g mol-1.

B2H6(g) + 6Cl2(g) → 2BCl3(g) + 6HCl(g)DrH° = -1396 kJ

◦ 352 kJ
◦ 508 kJ
◦ 156 kJ
◦ 57.8 kJ
◦ 215 kJ

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.
