3. What is photochemical smog‚ and how does it form? * Photochemical smog is a mixture of primary and secondary pollutants that react with UV radiation from the sun. * VOCs+ NOx+heat+sunlight→ground level ozone+photochemical oxidants+aldehydes+other secondary air pollutants 4. List five factors that can reduce air pollution and six factors that can increase air pollution. * See chapter outline notes‚

Introduction In a chromatographic separation process‚ different kinds of functional groups and number of functional groups of molecules will determine the separation. Depending on what kind of solute‚ solvent‚ and adsorbent used‚ molecules will experience the interaction during dynamic equilibrium. On a TLC plate‚ capillary tube is used to transfer o- and p- hydroxyacetopheone‚ taking advantage of capillary force to make small spotting. A 30:70 ether acetate: petroleum ether is used as a solvent
