Why do extremely dilute charged particles in an electric field move slower in an aqueous solution that contains other ions at much higher concentration in colution compare to the same particles in the same field in a non-aqueous, non-conducting medium (i.e. no ions present in this non-conducting solution)? Assume that the viscosity of both media is the same
The reaction 2NO ? N2 + O2, has a rate constant of 3.6 x 10^-2 M^-1 s^-1. When [NO]= 2.8 x 10^-3 M, what is the rate of change in M.s^-1 for N2?

How many grams of propane must be burned to provide the heat needed to melt a 75.0-g piece of bromine (at its melting point) and bring the resulting liquid to a boil (with no vapourization)? Assume a constant pressure of 1 bar and use the followin..
A 25.0-mL aliquot of vinegar was diluted to 250 mL on a volumetric flask. Titration of 50.0-mL aliquots of the diluted solution required an average of 34.88 mL of 0.09600 M NaOH. Express the acidity of the vinegar in terms of the percentage (w/v) ..
The initial concentrations of Pb2+ and Ag+ are 0.05M and for Cl- 1.5M. Assume all the present Pb2+ and Ag+ precipitate out of solution. Use the remaining Cl- concentration and the Ksp and Kf reactions for AgCl and AgCl2-, respectively, to determin..
