Calculate the cell potential E for a silver-silver chlroide lectrode immersed in 0.800 M KCl at 25 C.[Ag + e- -> Ag, E(standard) = 0.799 V , Ksp = 1.8 * 10^-10]
If a solution containing 46.46 g of mercury(II) acetate is allowed to react completely with a solution containing 7.410 g of sodium sulfide, how many grams of solid precipitate will be formed?
A 2L cylinder of gas contains 2.4 moles of gas at 34 degrees Celsius. What is the pressure?
Compute the boiling point of this solution if Kf and Kb for H 2 O are given as 1.86°C/m and 0.512 °C/m , respectively.
Cobalt was used as an internal standard to analyze a sample of titanium with atomic absorption spectroscopy. A mixture was prepared by combining a 5.50 mL Ti solution of unknown concentration with 2.00 mL of a 13.4 g/mL solution of Co
In an electrolysis cell similar to the one employed in this experiment, a student observed that his unknown metal anode lost 0.238 g while a total volume of 84.90 mL of H2 was being produced.
A solution is prepared by mixing 75.0 mL of 0.030 M BaCl2 and 250. mL of 0.040 M K2SO4. What are the concentrations of barium and sulfate ions in this solution? Assume only SO42- ions (no HSO4-) are present.
If 7.63 of an unknown gas occupies 79.1mL at 25.02 degrees celcius and 7.55 atm of pressure, what is the molar mass of the gas? R=0.0821
What effect would an increase in temperaure have on the experimentally determined Ksp of KHT?
it is found that the equilibrium concentrations in a 5.00 L rigid container are [H2] = 0.0500 M, [F2] = 0.0100 M, and [HF] = 0.400 M. If 0.338 mol of F2 is added to this equilibrium mixture, calculate the concentrations of all gases once equilibri..
