Widely used anti-inflammatory drug, Ibuprofen has a pKa value of 4.43. Stomach contents have pH range of 1.5-3.5, and small intestine has pH range of 6-7. Make an assumption, that the pH of stomach is 2.0 and the pH of small intestine is 7.0 Calculate the ratio between charged ibuprofen/uncharged ibuprofen at each digestive organ in the order of stomach and small intestine, and determine in which digestive organ most ibuprofen gets absorbed.

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
