Given a 0.010 M solution of a diprotic acid H2A with Ka1 = 2.9 x 10-5 and Ka2 = 5.3 x 10-6. The species present in the lowest concentration is
The rate constant for a certain reaction is K = 8.90×10^-3 . If the initial reactant concentration was 0.950 M, what will the concentration be after 14.0 minutes.
An aqueous solution containing 35.0% by mass of an unknown covalent compund in water was found to have a freezing point of -3.5 deg C. Calculate the molar mass of the unknown compund.
Determine the heat capacity of the calorimeter if you have 25g of water at a temp of 22.50 degrees C. Then add 10 g of water that has been heated to 100 degrees C and seal the calorimeter. If the equilibrium temp is 43.54 degrees C, what is the he..
Use the Nernst equation and data from Appendix D to calculate Ecell for each of the following cells. Enter your answer with 3 significant digits. Enter scientific notation as 1.23E4
Fortunately, you can narrow the search because the PVC piping comes from unique vendors each with their unique degrees of polymerization. By detailed measurement, you determine that the PVC molecular non-extended (i.e., coiled) length is 7 nm. Wha..
For the cell reaction, Cu^2+(aq) + Zn(s) (arrow) Cu(s) + Zn^2+(aq), E^* cell = 1.10V. Use the Nernst equation to determine E cell when the molar concentrations of Zn^2 and Cu^2+ are 1.0 M and 1.0 x10^-7 M, respectively.
