Procedure: (Describe here how you went about completing your experiment. Use enough detail that someone could repeat it, if necessary. Also reference any books or manual you may have used to assist you.) Data: Before Reaction: Mass of 250 mL side-arm flask __________ Mass of 5 or 6 pieces of solid zinc metal on Kimwipe _______________________ Mass of 1 Kimwipe _________________ Mass of 250 mL side-arm flask with CuSO₄ acidic solution _______________ Mass of CuSO₄ acidic solution alone _____________ Mass of Zn Metal alone____________ After Reaction: Mass of metal pieces on Kimwipe _______ Mass of 250 mL side-arm flask with CuSO₄ acidic solution _______________ Mass of solution alone _____________ Mass of metal pieces alone____________ Calculated mass of H₂ gas alone______________ Total mass before reaction___________ Total mass after reaction_______________ Mass % recovered after reaction ()________________ Calculations: (Show all calculations used to produce the above data here.) Conclusions: (Summarize your results here and discuss possible errors that may have occurred during the experiment. Does the mass you recovered support the law of conservation of mass? If it does, explain how it does. If it doesn’t explain, why it does not. How do the possible errors in your experiment affect your decision as to whether or not your experiment supports the law?)
