Calculate the standard enthalpy and entropy change for the reaction, given the following information:2 H2(g) + O2(g) → 2 H2O(g)∆H°f [H2O(g)] = -241.8 kJ/mol∆H°f [H2(g)] = 0 kJ/mol∆H°f [O2(g)] = 0 kJ/mol∆S° [H2O(g)] = 188.8 J/Kmol∆S° [H2(g)] = 130.7 J/Kmol∆S° [O2(g)] = 205.2 J/KmolAssuming that all heat capacities are independent of temperature, calculate ∆S°rxn and ∆H°rxn for this reaction.

How can we use UV-Vis spectroscopy to identify the presence of specific functional groups (such as carbonyl, aromatic, or alcohol groups) in a given compound? Can we determine the concentration of these functional groups using UV-Vis spectroscopy? How can we compare the UV-Vis spectra of different functional groups in order to distinguish them from one another?
