GENERAL INSTRUCTIONS
The entire report should be typed (handwritten portions will NOT be graded). Pleaseorganize your report as shown below. You and your lab partner may not work together onthe data analysis, or turn in the same work or answers to questions. If you need help withcalculations, you may ask for help from your instructor or the tutoring center.
DATA & CALCULATIONS
Part B:
Show typed calculations for the following values: mhot, ∆Thot, qhot, mcool,
∆Tcool, qcool, qcal, ∆Tcal, and Ccal.
Create a table of just the calculated values listed above, displaying eachvalue with proper units, mathematical sign and correct number ofsignificant figures.
Part C:
Show one set of typed calculations for the following values: msoln, ∆Tsoln,qsoln, qcal, qneut, mole of the limiting reactant and molar qneut. If youperformed multiple trials, only show calculations for one trial.
Create a table of just the calculated values listed above, displaying eachvalue with proper units, mathematical sign and correct number ofsignificant figures. If you performed more than one trial, report the valuesfor all trials in this table, as well as the average molar qneut.
QUESTIONS – All answers should be typed and given in complete sentences unlessotherwise indicated.
If some of the hot water evaporated during the heating process in part B, would thatcause the calculated value of Ccal to be too large, too small, or unchanged inmagnitude? Explain your reasoning.
Write the chemical equation for the reaction in part C and give the molar heat ofreaction. Based on the data, is the reaction in part C exothermic or endothermic?Explain your answer. As part of your answer, explicitly state from where and towhere the heat flowed during the reaction.
For each of the following components from part C, indicate whether they are part
of thea.b.c.d.e. f.
system or the surroundings.Styrofoam cupsThermometerHydrochloric acidSodium hydroxide
Water from the sodium hydroxide solution
Water product from the reaction
4. Give two possible sources for error that might have occurred during part C. Youranswer cannot be based on just ‘human’ error (examples: calculation error, notfollowing directions). Instead think about how the experimental set-up might leadto error.
