Introduction This lab proposed the question of what happens when copper chloride and iron are combined and what is the balanced equation.By completing this lab‚ the goal was to determine the equation and product for the reaction of iron (Fe) and copper chloride (CuCl2). It was predicted either solid iron or solid copper would form. Methods To begin‚ 6.00026 grams of copper chloride was dissolved in 50ml of distilled water in order to have a solution with charged iron and chlorine atoms. Then‚ 6

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

molecular formula of Copper Oxide through synthesis of copper oxide. In the first procedure‚ an empty crucible‚ Bunsen Burner‚ and electronic scale were placed onto the workbench. The electronic scale was zeroed before the crucible was placed on it. The total mass of the empty crucible was 88.000g. Afterwards‚ 10 grams of copper powder was placed into the crucible and weighed to be 98.000 g. The crucible with the copper was placed onto the Bunsen Burner. The initial color of the copper was red. The Bunsen
