write equations that show a plausible reaction mechanism for the light-catalyzed isomerization of methyl maleate
What is the pH halfway to the equivalence point for the titration of 0.20 M CH3NH2 with 0.20 M HCl? (Kb of CH3NH2 = 4.4 x 10-4)
Compare and contrast continuous spectrum and line spectrum as they relate to the elements. Describe how spectral lines can be used to identify elements.
constant- pressure calorimeter containing 80 g of water at 24.3 C. the final temperature of the system was found to be 28.8 C. Calculate the amount of heat that flowed into the water.
then dried the flask and added some pieces of titanium to it. the stoppered flask plus the titanium weighed 64.763g. then filled the flask w/water, leaving the titanium pieces in the flask, and found a mass of 67.561g for the flask plus titanium a..
Determine the number of grams of sodium acetate and the amounts in mLs of 6.00M acetic acid that you would need to make 50.00mL of a sodium acetate/acetic acid buffer solution at the pH equal to 5.00 in order to make a final concentration of 0.05M..
