Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here

The Effect of pH Level of a Liquid on the Rate of Corrosion of Copper wire In this experiment‚ I will be testing the corrosion rate of copper wire after leaving them in different liquids with different pH levels. By doing so I will be able to determine which pH level corrodes copper the fastest. I will conduct this experiment by pouring 250mL of different liquids with different pH levels in cups‚ followed by an iron strip placed into the cup. A stopwatch will be timing how long it takes the iron

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

6: The Copper Cycle CHEM 101 Lab-M/630 As an investigation of the copper cycle lab group 6 conducted an experiment on 6 October 2014 at Arizona State University laboratory that would demonstrate the cycle of reactions that copper (Cu) can produce when introduced to with other substances/reactant. The purpose of the investigation was to notice the transformation of a specific quantity of copper wire (g) as it undergoes its coordination reactions until a reduction method would yield copper (Cu) again
