Question description

 Part B.docx

1. Create one typed table that concisely presents the observations and answers to the questions in part A. Data for both calcium chloride and urea should be in the table.

2. Part B:

a. Show typed calculations for the following values: mhot, Thot, qhot, mcool, Tcool, qcool, qcal, Tcal, and Ccal.

b. Create a table of just the calculated values listed above, displaying each value with proper units, mathematical sign and correct number of significant figures.

3. Part D:

a. Show one set of typed calculations for the following values: msoln, Tsoln, qsoln, qcal, qneut, mole of the limiting reactant and molar qneut. If you performed multiple trials, only show calculations for one trial.

b. Create a table of just the calculated values listed above, displaying each value with proper units, mathematical sign and correct number of significant figures. If you performed more than one trial, report the values for all trials in this table, as well as the average molar qneut.



q. Write the chemical equation for the reaction in part D and give the molar heat of

reaction. Based on the data, is the reaction in part D exothermic or endothermic?

Explain your answer. As part of your answer, explicitly state from where and to

where the heat flowed during the reaction.
