He told the first responders that he was fine but feels a little short of breath all of a sudden. Jack tried to get out of the car on his own and gripped his chest in pain. When EMS rushed over he complained that the left side of his ribs was causing him excruciating pain. Upon physical exam his HR is 110 bpm, BP is 100/70 mmHg, RR is 24 bpm and breaths appear shallow. Auscultation of the chest reveals decreased breath sounds on the left side. Which of the following diagnoses do you suspect, and what is the next best step to confirm it?

Diаgrаm 9-1The mоleculаr оrbital diagram belоw may be used for the following problem(s). For oxygen and fluorine, the σ2p orbital should be lower in energy than the π2p orbitals. However, the diagram will still yield correct bond order and magnetic behavior for these molecules. Refer to Diagram 9-1. According to molecular orbital theory, which of the following lists ranks the fluorine species in terms of increasing bond order?
