Copper Synthesis Lab Report

Throughout the data and the observations got from this experiment, there are some reasons which may affected the mass of the copper was recovered and also the percentage of yield. According to the law of conservation of matter, the mass of the copper will not change even though there are many chemical reactions happened which also mean that the mass of copper contained in solutions or precipitates remain the same as the copper in the beginning.
And it is necessary to synthesize the various copper compounds in order to recover metal because the amount of copper might be left due to some errors during the experiments and the unreacted Zinc which still exist with recovered Copper which cause the percent yield increased. Besides, during the experiments,
