The organic matter present in a water sample could be from various sources. The release of pharmaceutical compounds from human excretion is an important contributor. For this example, let us consider a sample that contains 50 ug/L of the analgesic acetaminophen'. Calculate the total organic carbon (TOC, mg/L) in the sample due to acetaminophen. The molecular formula is C8H9NO2. Write a balanced chemical equation normalized to one mole of acetaminophen to show its oxidation to carbon dioxide and ammonia. The ammonia would further oxidize to form water and nitric acid. Write a representative balanced chemical equation for the ammonia produced in the first reaction. Use the balanced reactions from (b) to calculate the theoretical oxygen demand (THOD) of the water sample from (a) containing 50 ug/L of acetaminophen
