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.

Experiment 8 Name: Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of cach reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms...
