Thermochemistry please help me
Name: Lab Partner's names: Thermochemistry Lab Your instructor may ask you to answer these in your lab notebook, or to answer directly on this page and turn it in, or to include these answers in a formal lab report. Follow your instructor's directions 1. When 3.16 g of salicylic acid, CiHeOs, is burned in a bomb calorimeter containing 5.00 kg of water originally at 23.00 C, 69.3 kJ is evolved. The calorimeter heat capacity is 3255 Jrc. Calculate the final temperature. 2. Explain how the results would change if instead of using the Styrofoam cups, regular beakers were used in this experiment. 3. A calorimeter contained 75.0 g of water at 16.95 'C. A 933-g sample of iron at 6558 "C was placed in it, giving a final temperature of 19.68 "C for the system. Calculate the heat capacity of the calorimeter. Specific heats are 4.184 J/g·°C for H2O and 0.444 J/g. "C for Fe. 75
