What was your hypothesis? According to your data, do you think your hypothesis was correct? (Be sure to refer to your data and graph in answering this question.) Summarize any difficulties or problems you had in performing this experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.
Explain how a graphical analysis can be used to explore the relationship between any two scientific variables.

Idid a lab for chemistry where we put nails in a copper (ii) chloride solution. 1. why did the reaction stop? which reactant was used up? how do you know? 2. describe what was happening to the atoms of iron and copper during the reaction. what is this type of reaction called? 3. what would happen to the ratio of copper to iron if you had placed more nails in the beaker? if you had let the reaction go for less time? 4. what is the accepted ratio of copper atoms to iron atoms in this reaction? account for differences between your experimental value and the accepted value. write the balanced equation for the reaction.
