Lake Deposit You are an analytical chemist for the E.P.A. and a fearful citizen has brought in a metal sample from the bottom of the lake where this citizen frequently fishes and frolics. This citizen is sincerely worried and wants an accurate, precise, typed, and individual lab report by Thursday, March 3rd.

Formal Lab Report 1. Title (defining) 2. Purpose (defining) – complete sentences 3. Materials (observing) – list 4. Procedure (observing ) – no 1st person 5. Data (observing) – all quantitative and qualitative 6. Analysis (generalizing) – include source of error and explain exact effects on results 7. Conclusions (generalizing) – questions to answer

Conclusion Questions What is your unknown # ? 2. What is your unknown identity and why do you think so? 3. a. What is your % error (with 3 sig digs) for your density calculation? b. What is your % error (with 3 sig digs) for your specific heat calculation? 4. Based on the actual value, what is the ΔT in oC if 21.38 g of your metal absorbs 51.0 kJ of heat? 5. Based on the actual value, what is the mass in grams of 810 cm3 of your metal? 6. What is the environmental impact of the presence of your metal in the lake? (citation required)
