Complete the mechanism for the following mixed claisen condensation, where ethyl 2-phenylacetate is added dropwise to a solution of ethyl formate in ethoxide anion, by adding missing atoms, bonds, charges, nonbonding electrons, and curved arrows. note the resonance arrow between panels two and three.

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
