1.0 M HC2H3O2, and 1.0M NH3.
Calculate the concentration of HC2H3O2 or NH3 in each of the solutions you measured. By how many units did the pH of a solution of a weak base or acid change when it was diluted by a factor of ten?
What are the boiling point and freezing point of a 2.47 m solution of naphthalene in benzene? (The boiling point and freezing point of benzene are 80.1°C and 5.5°C, respectively.
Using a sample of 0.0355 gram of an unknown molecular compound is dissolved in 1.000 g of liquid camphor at 200.0°C. Calculate the molar mass of the unknown compound if the camphor freezes at 157.7°C upon cooling.
write equations that show a plausible reaction mechanism for the acid-catalyzed isomerization of maleic acid
This was allowed to react under reflux for an hour and then the products seperated. I wrote out a mechanism before lab and ended up predicting 4-chlorobenzoic acid and 4-chlorophenol as my final products.
Explain PH and Biochemistry, Determine the weight in grams of sodium dihydrogen phosphate (M.W.138.01) and disodium hydrogen phosphate (M.W 141.98) needed to prepare 1L of a standard buffer at pH 7.00, with a total phosphate concentration of 0.100..
A chemistry student needs 60.00 mL of chloroform for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of chloroform is 1.48 g x cm^-3.
