The following items are obtained from he Stockholm for the construction of a galvanic cell: two 250ml bearers and a salt bridge, a voltmetere with attached wires and clips, 200ml of a.0080M CrCl3, 200 ml of .12M CuSO4, a piece copper wire, and a chrome-plated piece of metal.
Draw and label the galvanic cell, then write and identify he two half-life reactions and write the overall cell reaction. Calculate E.
Write the cell diagram for the galvanic cell and calculate the expected cell potential
Light with a frequency of 7.11 x 10 -14 Hz lies in the violet region of the visible spectrum. What is the wavelength of this frequency of light? Answer in units of nm.
Calculate the equilibrium concentrations if the initial concentrations are 2.31M N2 and 0.54M O2. (This N2/O2 concentration ratio is the ratio found in air.)
The first step in the industrial recovery of zinc from zinc sulfide ore is roasting, that is, the conversion of ZnS toZnO by heating: calculate the heat of reaction
The solubility of KNO3 is 155g per 100g of water at 75 degrees C and 38.0g at 25degrees C. What mass in grams of KNO3 will crystalize out of solution if exactly 100g of it's saturated solution at 75 degrees C is cooled to 25 degrees C?
Seawater has a concentration of 400 ppm Ca. You wil first prepare a 10-fold diluted Buzzards Bay seawater solution (40.0 ppm Ca). Pipet 10.00 mL of Buzzards bay seawater into a 100.0 mL volumetric flask and fill to mark with deionized water
cyclohexane-toluene mixture, and then obtain IR spectra for each fraction. How would the IR spectrum of the first 1 mL fraction look different from that of the last 1 mL fraction?
Calculate the mass of precipiate formed when 110.0 mL of a 0.100M Ba(NO3)2 solution is added to 140.0 mL of a 0.100M Na2SO4 solution.
How many grams of O2 are needed to react with 20.9 grams of Mg?
What is the pH at the half-stoichiometric point (half-way to the endpoint) for the titration of 0.22 M HNO2(aq) with 0.10 M KOH(aq)?
zinc hydroxide is insoluble in water but dissolves when nitric acid solution is added
A 25.00mL portion of 0.00923M NaOH (MM 40.00g/mol) was introduced into the solution of H2SO4 (MM 98.08g/mol), then the excess was back titrated with 13.33mL of 0.01007M HCl (MM 36.46g/mol). Calculate the parts per million of sulfur in the sample.
Assume you carry out an experiment when the atmospheric pressure is 765mmHg and the temp in 24 degrees C. you collect Hydrogen gas and want to know the pressure of the gas
