    Introduction: Copper has played a vital role in past civilizations and continues to do so today due to its many properties as a metal. Although advantageous in today’s economy and also in human bodies‚ high concentrations of copper can prove toxic to our health and even pollutant to the environment. By altering the element through a number of chemical reactions including redox‚ metathesis‚ decomposition‚ and single replacement reactions‚ the cycle will be complete once solid copper is recovered.

    November 3rd‚ 2009 Lab Report #3: Copper Cycle Abstract: The purpose of the experiment is to cycle solid copper through a series of five reactions. At different stages of the cycle‚ copper was present in different forms. First reaction involves reaction between the copper and nitric acid‚ and copper changed from elemental state to an aqueous. The second reaction converted the aqueous Cu2+ into the solid copper (2) hydroxide. In the third reaction Cu(OH)2 decomposed into copper 2 oxide and water

    In this lab‚ we changed copper into various forms using different chemicals and chemical reactions. The purpose of this lab is to demonstrate that the product of a chemical reaction depends on what is present at the time of that reaction. This lab also displays how matter cannot be created nor destroyed in a chemical reaction. In a lab‚ you must always make safety a priority in case of an emergency. In our lab‚ we made sure to wear closed-toed shoes as well as goggles at all times. We also performed
