List the seven (7) contents of urine?

 Human urine consists primarily of water (91% to 96%), with organic solutes including urea, creatinine, uric acid, and trace amounts of enzymes, carbohydrates, hormones, fatty acids, pigments, and mucins, and inorganic ions such as sodium (Na+), potassium (K+), chloride (Cl-), magnesium (Mg2+), calcium (Ca2+), ammonium (NH4+), sulfates (SO42-), and phosphates (e.g., PO43-). A representative chemical composition would be:

water (H2O): 95%

urea (H2NCONH2): 9.3 g/l to 23.3 g/l

chloride (Cl-): 1.87 g/l to 8.4 g/l

sodium (Na+): 1.17 g/l to 4.39 g/l

potassium (K+): 0.750 g/l to 2.61 g/l

creatinine (C4H7N3O): 0.670 g/l to 2.15 g/l

inorganic sulfur (S): 0.163 to 1.80 g/l

Lesser amounts of other ions and compounds are present, including hippuric acid, phosphorus, citric acid, glucuronic acid, ammonia, uric acid, and many others

if you mean hydrogen and oxygen then water is the product
