Write the half-reaction that occurs at a hydrogen electrode in acidic aqueous solution when it serves as the anode of a voltaic cell?
what is the molarity of the base? Show clearly all strps of calculation please and a generalized chemical equation
Why are acid chlorides more reactive towards nucleophilic substitution than ethyl esters? Give an explanation of why acid chlorides are more reactive toward nucleophilic substition than are the corresponding ethyl esters.
this solution was added 1.960 grams of KI and 50.00 mL of a 0.00923 M KIO3 solution. The excess I3- was titrated with 50.00 mL of a 0.02000 M Na2S2O3 solution. What was the mass percent of arsenic trichloride in the original sample?
