I’m studying for my Chemistry class and need an explanation.
Procedure
Click the Experiment tab
Choose “Run Experiment”
Click on “Solutions” tab
Choose Hydrochloric Acid
Slide Volume slider to 100mL
Slide Molarity slider to 1.50M
Click the box next to “Show specific heat capacity”
RECORD THE INITIAL TEMPERATURE
Click Next
Click on “Solutions” tab
Choose Sodium Hydroxide
Slide Volume slider to 100mL
Slide Molarity slider to 1.50M
Click the box next to “Show specific heat capacity”
RECORD THE INITIAL TEMPERATURE
Click Next
Click the box next to “Show graph view”
Click the box next to “Show microscopic view”
Click Start
RECORD FINAL TEMPERATURE
Calculations
Assume the density of the solution is 1.00g/mL and determine the total mass of the solution in your calorimeter.
Calculate the change in temperature ΔT from your recorded temperature data.
Calculate the heat of the solution (qsoln) in the calorimeter.
Determine the heat of the reaction (qrxn)using conversion of energy.
Determine the enthalpy of the reaction by dividing the heat of the reaction by the moles of acid.
Compute the %accuracy for the enthalpy of reaction. Assume that the “correct”values for the enthalpy of reaction are ΔH = -58 kJ/mol acid for the reaction of sodium hydroxide with hydrochloric acid.
