1. Create a drawing of your electroplating apparatus for the coin (an electrolytic cell). Then submit your drawing with the following terms labeled correctly. Or, beginning with the positive terminal of the battery and ending with the negative terminal of the battery, describe the path that the electricity takes and where each of the following occurs:
1. cathode
2. anode
3. copper strip
4. battery
5. negative terminal
6. positive terminal
7. place where oxidation occurs
8. place where reduction occurs
9. electrolyte solution
10. coin
11. direction of electron flow
2) Describe the results of your procedure with the key
3. Write the two half-reactions that occur in the electroplating process under #2. Be sure to include the states of the elements or ions.

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
