I have a question for my chem class I just can't figure out...A thirteen-year-old girl, who is underdeveloped and thin, has a blood disorder. She frequently experiences chest and abdominal pain, fever, and coughing, and has trouble breathing. Her teachers often spend additional time with her, explaining concepts that the rest of the class is familiar with, as she tires very easily and is able to concentrate only for short spans of time.
