Question

An iron bar is to be electroplated with zinc. Draw a diagram to do so and:
-Identify what will act as the two electrodes for the cell
-identify each electrode as either the anode or cathode
-write the half-reactions occurring at each electrode
-identify a solution that would make a suitable electrolyte for this cell
-identify which electrode will be attached to the negative post of the battery and which will be attached to the positive post and explain.
-identify the flow of electrons

Answer 1

Can't draw a diagram/picture on this site. Take a beaker or vessel of some kind (vessel should not be a conductor of electricity and should not react with any of the contents). On the left side you will have a Zn bar dipping into an electrolyte, usually a special solution like methanesulfonic acid but less sophisticated ones in the lab can be found such as Na2SO4.
On the right you will have a Fe bar dipping into the same electrolyte solution.
You hook up a power supply with the + cable connected to the Zn bar and the - cable connected to the Fe bar. Turn on the power and the Zn goes into solution and becomes attached to the Fe bar. Post your work if this doesn't take care of all of the questions.
