A student performed chromatography on a mixture of benzoic acid (C₂H5CO₂H), acetophenone (C6H5C(O)CH3) and styrene (C₂H5CHCH₂). She used alumina (Al2O3) as the stationary phase and a 9 : 1 mixture of hexane : ethyl ethanoate as the mobile phase. Rank the order in which the compounds moved, from fastest to slowest. < benzoic acid acetophenone styrene

Calculate the change in (total) CO, in the ocean surface mixed (Temp = 25C, Salinity = 35 ppt) layer if 1 nM of iron is added (and consumed), assuming it is indeed the limiting nutrient. %3D b. Would this change in total CO, affect the alkalinity of the surface ocean? Why/why not? c. How much would the pH of the surface change following this primary production (assuming no respiration/gas exchange)? Use pCO2 = 420 ppm and total alkalinity = 2.2 mM to start your calculations. %3D
