A buffer is prepared by adding 23.0 g of sodium acetate (CH3COONa) to 490 mL of a 0.160 M acetic acid (CH3COOH) solution. Part A) Determine the pH of the buffer.
Part B) Write the complete ionic equation for the reaction that occurs when a few drops of hydrochloric acid are added to the buffer.
Part C) Write the complete ionic equation for the reaction that occurs when a few drops of sodium hydroxide solution are added to the buffer.
Please help with explanation. Thank you so much

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).
