If a box is not needed, leave it blank Use the table Standard Reduction Potentials' located in the 'Tables', to predict if a reaction will occur between Ni metal and C12(g), when the two are brought in contact via half-cells in a voltaic cell. If a reaction will occur, write a balanced net ionic equation for the reaction, assuming that the productions are in aqueous solution. If no reaction will occur, leave all boxes blank.
