Consider the following equation for a cell reaction

From the electrode, magnesium looses two electrons and chlorine gains two electrons. Therefore, balanced redox equation for the voltaic cell is as follows. The nuclide As has a half-life of If a sample of As weighs g, what mass of As remains after minutes? For the galvanic cell reaction, expressed below using shorthand notation, what half-reaction occurs at the cathode? In considering the half cell reactions in electrochemical cells, we consider the standard electrode potential of the two half cells. The more negative electrode potential will be the anode and the less negative electrode potential will be the cathode. For chemical reactions involving ideal gases, the equilibrium constant K can be expressed either in terms of the concentrations of the gases in M or as a function of the partial pressures of the gases in atmospheres. In the latter case, the equilibrium constant is denoted as Kp to distinguish it from the concentration-based equilibrium constant Kc sometimes referenced as just K. What is Kp for the reaction at this temperature? Express your answer numerically. Magnesium has three naturally occurring isotopes Mg, Mg, and Mg The atomic mass and natural abundance of Mg are Find the natural abundance of Mg Express your answer using two significant figures.

When the zinc atoms lose electrons the zinc ions go into solution and the 2 electrons flow away from this electrode into the external circuit. When they arrive at the copper electrode, they are picked up by the copper II ions to become copper atoms. The salt bridge consists of some filter paper soaked in a suitable electrolyte such as saturated potassium nitrate solution. From which electrode do electrons flow away from and into the external circuit? Calculate the e.

Consider the following equation for a cell reaction

When exposed to moisture, steel will begin to rust fairly quickly. This creates a significant problem for items like nails that are exposed to the atmosphere. The nails can be protected by being coated with zinc metal, to make a galvanized nail. The zinc is more likely to oxidize than the iron in the steel, so it prevents rust from developing on the nail. In order to function, any electrochemical cell must consist of two half-cells. The table below can be used to determine the reactions that will occur and the standard cell potential for any combination of two half-cells, without actually constructing the cell. The half-cell with the higher reduction potential according to the table will undergo reduction within the cell.
