Using Le Chateleir's principle, explanin the effect on teh cell potential of decreasing the Fe2+ ion concentration from 1.0M to 0.1M for each of the following reactions. The concentration of the other solution remains at 1.0M.
Fe2+ (aq) +Zn(s) ? Fe (s) + Zn2+ (aq)
Fe(s) + Cu2+ (aq) ? Fe2+ (aq) + Cu(s)
A voltic cell with an aqueous electrolyte is based on the reaction between Cd2+ (qu) and Mg(s), producing Cd (s) and Mg2+. Write a balanced cell reaction.
Calculate the pH and the concentrations of all species present in a 0.19-M solution. The acid dissociation constants are K1 = 5.9 10-2 and K2 = 6.4 10-5.
In the chemical kinetics experiment, describe how you plan to mix the dye and bleach to start the reaction and when you expect to start recording the time? Include the volumes of dye and bleach solution you intend to mix? How are you going to make..

Consider the peaks for pentafluorobenzene (12.98min) and benzene(13.20min) in the chromatogram shown above. The elution timefor the unretained solute is 1.06 minutes. The open tubularcolumn is 30.0m in length and 0.530mm in diameter, with a layer ..
A mixture of nitrogen and oxygen gas is collected by displacement of water 30 degrees celsius and 700 torr Hg pressure. If the partial pressure of nitrogen is 550 torr Hg, what is the partial pressure of oxygen? (Vapor pressure of H2O at 30 degree..
if you burn 33.7g of hydrogen and produce 301 g of water, how much oxygen reacted?
Which statement best describes relationships in a modern periodic table? A.) Each transition element is placed in the column of the main group element that it most closely resembles.
Place a coffee cup that holds hot coffee in a cold room and let it sit there for 4 hours. Consider the coffee inside the coffee cup as your system
Kinetic Molecular Theory states that particle collisions are elastic,but energy and collisions of the particles are proportional to the absolute temperature, but the more collisions according to Henry's law, the more gas dissolves.
Determine the concentration of CO32? ions in a 0.18 M H2CO3 solution. Carbonic acid is a diprotic acid whose Ka1 = 4.3 x 10?7 and Ka2 = 5.6 x 10?11
