In an experiment, you dissolve 0.30 g of khp (mm = 204.22 g/mol) in 20 ml of di water and titrate the sample with 0.10 m naoh. calculate the volume (to the nearest ml) of naoh required to reach the equivalence point. 3 15 20 30 100

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).
