What are the relative percentages of hydrogen cyanide (HCN) and cyanide ion in a dilute aqueous solution at pH= 9.2 At PH=10.2.
Determine the second order rate constant from the initial concentration and half life and what is the second order rate constant?
The design calls for reheating the liquid after the temperature has dropped to seventy degree Celsius the determine about how many stags and how many heaters are required for this process?
Magnesium hydroxide is only very slightly soluble in water. The reaction by which it goes into solution is: Mg(OH)_2 (s) Mg^2+ (aq) +2 OH- (aq)
You are fortunate to land a research position with Dr. Xavier Wray. Your first day in the lab the good doctor asks you to make a liter of 0.1 M citrate buffer pH 3.5 that you will need for the big extract procedure he will show you how to do after..
Draw the structure(s) of the epoxide(s) you would obtain by formation of a bromohydrin from cis-3-heptene, followed by treatment with base
find the ph of the two equivalence points and the volume (ml) of 0.0414 M KOH needed to reach them in the titration of 17.3 mL of 0.130 M H2co3 (first equivalent point = ML KOH, and pH= )
what is heat of vaporization of a liquid that has a vapor pressure of 606 torr at 84 degrees celsius and a boiling point of 96.3 degrees celsius at 1 atm?
Draw the structures and then List the following alkyl halides in order of their increasing reactivity as substrates in SN2 reactions
Calculate the pH of each of the solutions and the change in pH to 0.01 pH units caused by adding 10.0 mL of 3.48 M HCl to 350 mL of each of the following solutions
Indicators can be used to estimate the pH value of soultions. To determine the pH of a 0.01M weak acid (HX), a few drops of three different indicators are added to separate portions of HX. The resulting colors of the HX solution are below.
