| Answer the following questions and write the equations (molecular and net ionic) for all reactions that occur.
a. Will sodium metal react with water?
b. Does nickel react with water? with HCl? with a tin nitrate solution?
c. Will gold react with a nickel nitrate solution?
d. Will tin react with water? with a gold chloride solution?
e. List the four ways we can identify that a chemical reaction has occurred.

| A piece of platinum is placed in a solution containing chromium ions. No reaction is observed. A piece of chromium is then placed in a solution containing tin ions. A solid different than the chromium seems to appear. When a piece of platinum is then placed in a solution containing tin ions, no reaction is observed. Order these metals as they would appear in an activity series. (You can check your answer by looking at the example series from the background section.)
