What is the pH of a buffer solution of phenol and its conjugate base. [C6H5OH] = 0.11 M and [C6H5O]- = 0.80 M.
Write the cell notation for a voltaic cell with the following half-reactions.
The reaction OH(aq) + HCN(aq) H2O(l) + CN(aq) is first-order in both the OH and HCN concentrations. The rate constant at 25oC is 3.7×10^9 mol^-1 L s^-1
How can their efficiency be less than 100% and the Law of Conservation of Energy still be valid? An incandescent light bulb functions because of the flow of electric current. Does the incandescent light bulb convert all of the electrical energy to..
