Outline a mechanism for the phtolysis of methyl butyrate assuming the reaction follows a patter similar to 2-pentanone.
A flask contains 0.330 mol of liquid bromine, Br2. Determine the number of bromine molecules present in the flask.
210 mg Ca(OH)2 and 210 Al(OH)3. A 8.3×10^-2 M HCl, which is similar to stomach acid, is used to neutralize 5.0mL of liquid antacid. How many mililiters of HCl solution are needed to neutralize Ca(OH)2, then Al(OH)3?
A sample of vanadium haveing 5.67 grams of mass upon heating combined with oxegen of 4.45gramsto make vanadium oxide. Determine the emperical formula for this compound?
What final temp. would be required to increase the pressure to 1 atm, the volume being held constant?
A sample of chlorine gas at a pressure of 420 mm Hg and in a volume of 3.50 L was heated from 18.0oC to 45.0oC after being transferred to a container of volume 2.35 L. The pressure in this new container should be about
