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.

A chemistry student needs to determine the Langmuir constant and maximum adsorption capacity of a metal oxide nanoparticle using the Langmuir adsorption isotherm equation from experimental data obtained at different concentrations of a given adsorbate in the water. Determine the Langmuir equation parameters and plot the experimental data and the Langmuir model using a graph. Finally, interpret the results in terms of the adsorption behavior of metal oxide nanoparticle towards the selected adsorbate.
