Calculate the volume of 6 M NaOH required to react completely with the amount of methyl salicylate you used. How much of the 6 M NaOH that you used was in excess of the theoretical amount? We started off with 2.00 mmol or 0.002 moles of methyl salicylate and we added 2.5 ml of aqueous 6 M sodium hydroxide
C8H8O3 + 2NaOH-----> disodium salicylate and water
Proceeds at a certain temperature until the partial pressures of H2O, H2, and O2 reach 0.065 atm, 0.0070 atm, and 0.0040 atm respectively. What is the value of the equilibrium constant at this temperature
What is the maximum concentration of Ba2+ that can be added to a solution containing 1.5 X 10^-2M of F- without precipitating BasF2? Ksp = 1.7 x 10^-6
Compute mole fraction of caffeine(C 8 H 10 N 4 O 2 ), the molarity of the solution
You perform column chromatography on a mixture of reaction products which shows two spots on TLC. However, under the column conditions you chose those two compounds do not separate.
Which solution would increase the osmotic pressure of water the most?
there is no measurable difference between final and initial pH - that is why it is called a buffer E. final pH is 0.16 pH units lower than original pH
This race is a challenge to the human organism! By what percentage does the oxygen number density decrease between the start and the finish of the race?
Write a complete stepwise mechanism for the reaction of cyclopentanone with bromine in acetic acid to give 2-bromocyclopentanone. Show all intermediate structures and all electron flow with arrows.
The cell constant of a conductivity sell is equal l/A. The resistance of the NaCl solution is found to be 254 Ω . Using the same sell the resistance of the 0.05 M KCL is found to be 467 Ω . Estimate the NaCl concentration if the molar conductivity ..
For the next three problems, consider 1.0 L of a solution which is 0.3 M HC2H3O2 and 0.2 M NaC2H3O2 (Ka for HC2H3O2 = 1.8 x 10-5). Assume 2 significant figures in all of the given concentrations so that you should calculate all of the following pH..
Calculate the value of each partition function. c) Use the TST to calculate the rate constant for the reaction D + H2à DH + H
What is the final temperature of the water when equilibrium is reached? (Assume a density of 0.998 (g/mL) for water.)
