Expert Answer

Step 1

In chemistry, there are many ways to check the deviation of experimental data from the accurate value. These different methods provide the difference between accuracy and precisions of the experimental data which can be further used to calculate the error percentage in the experiment.

Step 2

The balance reaction equation is:

CuSO42 Na
Na2SO Cu
