Some specific guidelines for the Copper Sulfide lab report

1. All sections are required
2. Theory - You should discuss transition metals and why they have multiple oxidation states (as opposed to, say ,Group I metals which are always +1 and only +1).  What are the common states of copper and how do you use them to predict the possible formulas of your product.  What are possible side products (i.e. compounds other than the anticipated product that could also form under these conditions.  Hint - consider things like the presence of oxygen).  One paragraph should be sufficient here.
3. Calculations - be sure you do all the calculations mentioned in the lab manual.
4. Error Analysis - be sure you do all the calculations and answer all the questions pertaining to error that are mentioned in the lab manual.
5. Be sure you consider significant figures!  You should be able to justify your choice of the number of significant figures you use in your answer.  If your class data contains values of varying numbers of sig. figs. (which is quite likely) don't worry about it, just report your answers to the number of sig. figs. that you feel are appropriate.
6. Conclusion - be sure you take the guidelines for this section to heart!  This should be a summary of your results - for example, be sure you report your formula here even though it is also in your Results and/or Calculations section
7. Answer the 4 "questions" posed on page 43 in the Questions section
8. Be sure that all numbers that should have units on them do have units!!!
