Question 1

The values of ΔH°f for the three states of benzene are approximately -22 kcal/mol, -11 kcal/mol, and Which is the value for solid benzene?
◦ 20 kcal/mol
◦ -11 kcal/mol
◦ -22 kcal/mol
◦ cannot be determined without additional information

Question 2

Which equation represents the reaction whose ΔH, represents the standard enthalpy of formation of CHCl3(l) at 25°C? (i.e., for which is ΔH = ΔH°f of CHCl3)
◦ C(s) + 1/2 H2(g) + 3/2 Cl2(g) → CHCl3(l)
◦ 2 C(s) + H2(g) + 3 Cl2(g) → 2 CHCl3(l)
◦ C(s) + H(g) + 3 Cl(g) → CHCl3(l)
◦ CHCl3(l) → C(s) + H(g) + 3 Cl(g)

Did you know?

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
