Discussion Questions: Answer the following questions in your la notebook. 1. For this experiment we assumed the calorimeter was a perfect insulator (no heat was lost to the surroundings), Is this a good assumption? Explain your answer. 2. Why is Nathe only spectator ion in this reaction? Why do we exclude Na+ from the theoretical Aretoan (calculation g)? Why are the other species from the reaction included in the calutations? 3. A student is supposed to add 25mL of 3M sodium hydroxide and 25mL of 3M phosphoric acid to a calorimeter. By mistake, and without his knowledge, he adds 25ml. of 2.5 sodium hydroxide instead of 25 mL of 3M sodium hydroxide. How will this impact the accuracy of his calculated heat of reaction? Will his results be erroneously high, erroneously low or will his results be accurate? Explain in detail. Refer to the equations you used in your calculations 4. What would be the impact on the calculation of Aran, if instead of using the limiting reactant a student used the excess reactant for the number of moles water? Would the results be valid
