In previous syntheses involving equilibria (like the Fischer esterification), one reactant was used as a solvent to achieve maximum conversion of the other to product. In the case of our crossed aldol condensation, using acetone as the solvent is not expected to achieve the desired goal. Explain why this is so by hand-drawing the major product which may form from this week’s synthesis when a large excess of acetone is mixed with the other reagents at the start of the reaction.

The chemical composition of soil varies with depth. an article in communications in soil science and plant analysis describes chemical analyses of soil taken from a farm in western australia. fifty specimens were each taken at depths 50 and 250 cm. at a depth of 50 cm, the average no3 concentration (in mg/l) was 88.5 with a standard deviation of 49.4. at a depth of 250 cm, the average concentration was 110.6 with a standard deviation of 51.5. find a 95% confidence interval for the difference in no3 concentrations at the two depths.
