A 25.00-mL solution of 0.1500 M methylamine (CH3NH2) is titrated with a standardized 0.1025 M solution of HCl at 25°C. Enter your numbers to 2 decimal places. Kb = 4.4x10-4 What is the pH of the methylamine solution before titrant is added? 11.91 How many milliliters of titrant are required to reach the equivalence point? 36.59 What is the pH at the equivalence point?

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).
