A student wishes to prepare a buffer solution by adding 0.20 moles of acetic acid (Ka = 1.8 x 10^-5) and 0.20 moles of sodium acetate in 1 liter of solution. The student adds 0.05 moles of hydrochloric acid (HCl) to the solution. Calculate the effect of adding the buffer on the equilibrium position of the acid-base reaction and determine the new pH of the solution.

A student has a sample of an unknown inorganic compound that contains only carbon, oxygen, and nitrogen. They perform a combustion analysis on a 0.230 g sample of the compound, which yields 0.535 g of CO2 and 0.184 g of H2O. Additionally, when the compound is analyzed using a mass spectrometer, the mass spectrum shows a molecular ion peak at m/z = 42. Determine the empirical and molecular formulas of this compound.
