-1300 kJ. With the graph showing an exothermic reaction, and the result pointing to the same result, the findings help to further express the confirmation of the thesis of this experiment. The physical observations of the experiment itself did show that a replacement reaction took place, as the presence of the aluminum continued to decrease in favor of a more solid residue of solid elemental copper. This on top of a change in mass, shows that the reaction did successfully take place.

The standard deviation could have been through random error, which would explain the deviation of 140 kJ. As for terms of creating a more accurate measurement, there’s the possibility of using digital scales to more significant places, as well as experimenting with other forms of the solution and molarities to see how it changes the standard enthalpy, and helps to show the increase, whether significant or otherwise of the reaction. The total experiment itself did manage to prove the thesis, however it seems to be that there is plenty of more improvement that is possible, however, in the end what there is so far was a successful experiment.

    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.
