You are tasked with creating an electrochemical cell that has a specific cell potential of +0.0577 at 25 degrees C. The only chemicals you have available are Cu(s), CuSO4(s), and H2O, although you have access to any glassware and equipment that you would need to set it up. The Cu2+(aq)/Cu(s) reduction potential, under standard conditions, is E= +0.337 V. Describe how you would construct your target electrochemical cell, including the identities and concentrations of all chemical species, as well as a diagram of the setup.
A 1-L flask is filled with 1.10 g of argon at 25 C. A sample of ethane vapor is added to the same flask until the total pressure is 1.20 atm . What is the partial pressure of argon,PAr , in the flask?
