In the experiment‚ synthesis of copper compounds‚ the purpose was to recover the original amount of copper after series of chemical reactions. Then returning the copper back to its original form. The copper wire originally weighted 1.0099 g‚ but after the copper was transformed into Cu(OH)2 to CuO to CuSO4 and finally into Cu‚ the mass of the recovered copper was 1.1023g; the percent yield was 109%. Since the percent yield is more than 100%‚ an error must have occurred somewhere in the lab. A possible
