As shown above, the experiment yielded us 0.0168551mol of Copper using 0.01796401mol of Iron.
Looking at the two chemical equations below. It can calculated that the ratio of moles of iron to copper
needed in the first reaction is 1:1, while the second reaction requires a mole ratio of 2:3 Iron:Copper to
take initiate. Since our results have shown that we gained equal amounts of Copper and Iron moles
(within accepted experimental error), we can conclude that the equation of this reaction is equation
one.
Equation 1

Sources of Error
The major sources of error in this experiment include, the precision of items like the graduated cylinder
and balance. Error could also happen in the decanting process, since multiple decants are preformed, a
slight error in each process could compound and have noticeable effects.
