The bromination of acetone is acid-catalyzed. CH3COCH3 + Br2 CH3COCH2Br + H+ + Br -
The rate of disappearance of bromine was measured for several different concentrations of acetone, bromine, and H+ ions at a certain temperature.
[CH3COCH3] [Br2] [H+] Rate of disappearance of Br2 (M/s)
0.30 0.050 0.050 5.7 10-5
0.30 0.10 0.050 5.7 10-5
0.30 0.050 0.10 1.2 10-4
0.40 0.050 0.20 3.1 10-4
0.40 0.050 0.050 7.6 10-5
(a) What is the rate law for the reaction?
Rate = k[CH3COCH3][H+][Br2]
Rate = k[Br2][H+]
Rate = k[CH3COCH3][H+]
Rate = k[CH3COCH3][Br2]
(b) Determine the rate constant.

Achemistry student weighs out of phosphoric acid , a triprotic acid, into a volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with solution. calculate the volume of solution the student will need to add to reach the final equivalence point. round your answer to significant digits.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

Some liquids can be distilled, but only at temperatures that are so high that it is impractical, or so high the compound decomposes. explain why distillation such compounds at significantly less than atmospheric pressure (some degree of vacuum) would solve this problem.
