25.3mL of water was filled into the beaker alongside 8.014g of copper (II) sulfate. At the point of having the proper temperature, 1.100g of iron was included. The completion measure of copper that was made from this response was 0.738g. This was a deficient value due to human error. This was obvious when the chemical mixture was stirred as opposed to letting it sit and accumulate at the base of the beaker. This caused a portion of the copper flakes to remain ascended as opposed to sinking to the base, so, when the decanting process started, those flakes were lost. A portion of the steps that were taken to try and diminish error, were when measuring the iron and the copper (II) sulfate, it was pivotal to get them as close as possible to the exact amount that was described in the procedure. Additionally, while warming up the water, extra attention was used to ensure that the water didn't bubble and demolish the experiment.

Table 1 : Calculations of the Copper Yields Produced Theoretical Actual Percentage 1 1.252g 1.054g 84.19% 2 1.878g 1.054g 56.12% Section 3: The claim made was that reaction 1 [CuSO 4 (aq) + Fe(s) FeSO 4 (aq) + Cu(s)] was the reaction that occurred. The claim was justified due to the fact that it was closer to 100% than reaction 2, which means it was closer to the maximum theoretical yield. To find the theoretical yield, these two equations were used: Reaction 1: (1.100g Fe x 1 mole Fe x 1 mole Cu x 63.55g Cu)/(55.85g Fe x 1 mole Fe x 1 mole Cu) = 1.252g; Reaction 2: (1.100g Fe x 1 mole Fe x 3 mole

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
