Question 1. What percent error does the neglect of the calorimeter

Question : Question 1. What percent error does the neglect of the calorimeter : 956104

Question

1. What percent error does the neglect of the calorimeter constant introduce into your results for the specific heat of copper? 2. Briefly discuss whether the following experimental mistakes would have no effect, product a high result, or produce a low result in the value calculated for the specific heat in your experiments. a. The mass of aluminum was smaller than reported. b. If 45 mL of distilled water was used in the calorimeter rather than 30. c. The actual calorimeter constant is larger than the assumes value. 3. What effect would an uncertainty of 0.5C in reading all temperatures have on the determination of the specific heat of copper in your experiment? 4. A student measures the heat capacity of a 35.0 g metal sample bylined to be pure silver (Cp = 25.5 J mol^-1 deg^-1. Subsequent analysis indicates that the metal sample is 80% silver and 20% copper. In what way will the observed heat capacity of the metal mixture front the value obtained for pure silver? Explain your answer fully and show all calculations used in arriving at an answer.
