The cell potential of the subsequent electrochemical cell depends on the gold concentration in the cathode half-cell.
Explain what is the concentration of in the solution if is 1.19?
A 1.00L Solution contains 3.50x10^-4 M Cu(NO3)2 and 2.20x10^-3M ethylenediamine(en). The kf for Cu(en)2^2+ is 1x10^20. What is the concentration of Cu2+(aq) in the solution
Assuming efficiency of 26.70 %, calculate the actual yield of magnesium nitrate formed 139.4 g of magnesium and excess copper (II) nitrate. Mg + Cu(NO3)2 -> Mg (NO3)2 + Cu
why we call benzene phenyl and not benzyle when one hydrogen is removed because in case of alkanes we name them alkyl on the removal of one hydrogen atom.
Draw the major organic product of the regioselective reaction of 2-methyl-2-pentene with Hg(OAc)2 in presence of H2O. In your answer draw the expanded structure for the acetyl group (Ac). Ignore stereochemistry.
Urea { (NH2)CO } is used for fertilizer supplyingnitrogen to the soil. Calculate the number of N atoms foundin 1.68 * 10^4g of urea.
A solution of an unknown nonvolatile electrolyte was prepared by dissolving 0.250 g of a substance in 40 g of CCl4. The boiling point of the resultant solution was 0.357 degrees Celsius higher than that of pure solvent. Calculate the molar mass of..
give an explanation for how calmagite works as an indicator for the titration of magnesium ion with edta. explain why
Some 2-methyl-2-butene may be produced in the reaction as a by-product. Give a mechanism for its production. (The experiment was to react t-pentyl alcohol with HCl.)
The pressure was exerted with a piston on molten naphthalene at 95 degrees C. The vapor pressure of naphthalene under 1.0bar is 2.0kPa and its density is 0.962g/cm^3. What is its vapor pressure when the pressure on the liquid is 15MPa
Calculate the pressure and temperature at which 1.0 mol of H2O, HCl, and C6H6 corresponds to the same states as 1.0 mol of CH4 at 2.00 atm and 298
The density of the sample is 1.01 g/mL. The titrant is 1.017 M NaOH. The average volume of titrant required to titrate 25.00 mL subsamples of the vinegar is 20.78 mL.
A 280ml flask contains pure helium at a pressure of 754 torr . A second flask with a volume of 475ml contains pure argon at a pressure of 732 torr . If the two flasks are connected through a stopcock and the stopcock is opened, what is the partial..
