Write out a detailed mechanism for the formation of dibenzalacetone, using acetone + benzaldehyde in NaOH. Please show steps with electron arrow movement.
A 235mL solution is prepared with 41.8 millimoles of an unknown sodium salt of a deprotonated organic acid (NaX). If the solution has a pH of 8.05, what is the pKa of the acid?
calculate the pressure exerted in the closed end of an apparatus if the atmospheric pressure is 720.0 torr and the height of the water column is 22.3 cm.
Determine the concentration of a solution prepared by diluting 25.0 milliliters of a 12 molar HCl solution with H2O until the final volume is 2.50 x 10² milliliters.
A piece of metal of mass 27 g at 99?C is placed in a calorimeter containing 45.1 g of water at 21?C. The final temperature of the mixture is 38.7?C.
