Activity Data
... [Show More] Code: MCQ
Table I – Raw Reaction Data
Complete the table below using data from your Temperature Plots (see the Temperature Plots tab). Note: You should have data from four separate Temperature Plots.
Observations and Questions
[1] Which reaction is exothermic and which is endothermic? What in your data leads to this conclusion? Eventually, the temperature of the reaction solution stops changing. Why?
[2] Describe and explain anything else that happens during each reaction (other than a temperature change).
Table II – Mass of Solution
Complete the table below using data found under the Activity-Form tab (density), volume data from Table I, and information found under the Background tab (see the Summary of Needed Formulas section near the end).
Sample Calculation: Show your mass calculation for Reaction 1 (trial 1).
Table III – Moles of Reactant B
Complete the table below using data found under the Activity-Form tab (concentration), volume data from Table I, and information found under the Background tab (see the Summary of Needed Formulas section near the end).
Sample Calculation: Show your moles of Reactant B calculation for NaCl (trial 1).
Hint: see the Summary of Needed Formulas section under the Background tab.
Table IV – Heat of Reaction
Complete the table below using data from Table I (temperature), data from Table II (mass), data from Table III (moles of Reactant B), and information found under the Background tab (see the Summary of Needed Formulas section near the end).
Note: Be careful! Mass must be in kilogram (kg) here not grams (g). Note: 1000 g = 1.000 kg
Remember that ΔT = TFinal - TInital and that ΔT can be positive or negative.
Report Solution Heat Transfer in kilojoule (kJ) here not joule (J). Note: 1000 J = 1.000 kJ
Report Heat of Reaction per Mole in kilojoule per mole (kJ/mol) here not joule per mole (J/mol).
Sample Calculation: Show your solution heat transfer calculation for Reaction 1 (trial 1).
Sample Calculation: Show your heat of reaction per mole calculation for Reaction 1 (trial 1).
Calculation: Using the ideal gas law, and your reaction data, determine the volume of carbon dioxide you would collect from Reaction 1 (trial 1) at 20.00 C and 1.00 atm. [Show Less]
