A nickel-metal hydride rechargeable battery formerly used in laptop computers is based on the following chemistry: Cathode: Anode: The anode material, MH, is a transition metal hydride or rare earth alloy hydride. Explain why the voltage remains nearly constant during the entire discharge cycle.
Fall, 2014 ACycle of Copper Reactions Objective: To observe different kinds of reactions starting with copper metal, converting it into copper compounds, than recovering it as copper metal in the end without losing any copper. Introduction: There are a relatively small number of chemical elements, perhaps one hundred, that can be used in chemical synthesis (this excludes man-made, radioactive elements with very short half lives that don't exist very long). From these relatively few chemical elements all of the complicated material structure of our universe is constructed. The ChemicalAbstracts Service advertises that they have registry information for 48 million compounds—all formed by combining these one hundred or so elements in various ways. The for
