3) A 28 yr old woman is newly sober for the past 3 months after completing an intensive outpatient recovery program. She wants to hang out with her co-workers at happy hour in a local club. She is anxious but goes out with them and orders a soda. She feels good that she was able to go out and not have an alcoholic drink. The following week the same scenario plays out without her having an alcoholic beverage. Is she on the path to staying sober or on the road to relapse? Why?

CONCLUSIONS: In general, the boiling points of compounds increase down a group in the periodic table. The melting points and boiling points for the hydrogen compounds of group 6A elements are in the table below. Melting Point (°C) Boiling Point (°C) H₂O 0.0 100.0 H₂S -82.0 -60.0 H₂Se -65.7 -41.2 H₂Te -49.0 -2.2 Use your understanding of chemistry to propose an explanation for the anomaly in the trend for the hydrogen compounds of group 6A elements shown in the table.
