Change in enthlapy, AH, and heat of reaction, gen To calculate the total amount of heat (energy) being transferred in the calorimeter, the following equation for the heat of solution (ul) is used: alu-mCAT where 772 is the mass. C is the specific heat, AT is the change in temperature of the solution, and g is equal to the energy change of the solution (i.e.. it can be a positive or negative value). When the mass of solution is unknown, the density and volume of solution can be used to calculate it, where a density of 1.00 g/mL (water) is used to approximatem if the exact density is unknown. The specific heat of water (4.184 J/(g°C)) can then be used to calculate q... The calorimeter is insulated (preventing energy exchanges with the environment outside of the calorimeter), so the energy change for the reaction (grxn) is equal and opposite to the energy change taking place in the surroundings (go); i.e. Atsu = −4wlu because the net flow of energy goes in only one direction. Lastly, the enthalpy change, AH, is the amount of energy being released or absorbed by the reaction per mole (n) at constant pressure. The relationship between the enthalpy and heat of reaction is ▼ Part D For this exercise, you can simulate the described conditions by changing the values in the Run Experiment tool, under the Experiment tab, in the simulation. The hints run through each step in the calculation, where the equations are given before this part. The second hint calculates the temperature change, which is the only step that requires the simulation. Use the simulator to react 76 ml. of 1.6 MHCI with 76 ml. of 1.6 M NaOH at an initial temperature of 20.00 °C; note the final temperature. Use the data from the simulation to calculate the change in enthalpy per mole of product (n). Estimate the density of the liquid to be 1.00 g/mL. Express your answer in kilojoules per mole to three significant figures. ▸View Available Hint(s) ΔΗ = IVE ΑΣΦ Ĉ AH 2 kJ/mol
