Two 100 ml granulated cylinders. In each cylinder 40.0 ml of water. you also have two cubes: one id lead the other is aluminum. Each cube measure 2.0 cm on each side.After you carefully lower each cube into the water of its own cylinder, what will the water level be in each cylinder?
Consider the cell described below. Al | Al3+ (1.00 M) || Pb2+ (1.00 M) | Pb Calculate the cell potential after the reaction has operated long enough for the [Al3+] to have changed by 0.32 mol/L. (Assume T = 25°C.)
The hydrogen carbonate ion can act as both an acid and a base. Write out two equations which demonstrate this and calculate (or look up) the equilibrium constants for both expressions
The solubility of AgCrO4 is several times greater than that of AgCl, so the red precipitate cannot form until all the chloride ions have effectively been removed from the solution.
