What will be the value of E cell and E0 cell when the Cu/Zn battery has "run down" I.e., reached equillibrium? Also will the concentrations of Zn2+ and Cu2+ be large or small when the battery has "run down"? Does this make sense?
you want to carry out chemical reaction that is water sensitive, however the glassware contains salts and you need water to wash them out. the reaction you are going to perform can be done either in acetonitril or toluene
Ammonium Carbonate, NH4CO2, decomposes as follows: NH4CO2NH2(s) -> 2NH3(g) + CO2(g) Starting with only the solid, it is found that at 40C the total gas pressure is .363 atm. Calculate Kp.
