Complete the mechanism for the base-catalyzed racemization of the chiral ketone below by adding any missing atoms, bonds (wedge/dash, too), charges, nonbonding electrons, and curved arrows (forward reaction only).
An equilibrium mixture in a 2.00 L vessel is found to contain 0.0406 mol CH3OH, 0.170 mol CO, and 0.302 mol H2 at 500 K. Calculate Kc at this temperature.
A 49g piece of ice at 0 degrees C is added to a sample of water at 9 degrees C. All of the ice melts and the temperature of the water decreases to 0 degrees C.
A 1 L solution of 1.5 M acetic acid and 1.5 M sodium acetate has a ph of 4.74. 10 ml of 0.1 M NaOH were added to the solution followed by the addition of 50 ml of 0.02 M HCl.
