The enthaply of neutralization of Phosphoric Acid

Please help with 1-5

The Enthalpy of Neutralization of Phosphoric Acid DATA TABLE Trial 3 Trial 1 Trial 2 Maximum temperature (c) 3 Initial temperature ("C) Temperature change (AT o C DATA ANALYSIS 1. Write the balanced equation for the reaction of phosphoric acid and sodium hydroxide. 2. Use the equation below to calculate the amount of heat determining the mass, m, of the solution use 1.11 g/mL for the density. Use 4.18 J/Kg. C) as the specific heat, Cp, of the solution , g, produced in the reaction. In 3. Use the heat energy that you calculated in 2 above to determine the enthalpy change, AH, for the reaction in terms of kJ/mol of phosphoric acid. This is your experimental value of ΔΗ 4. Use a table of standard thermodynamic data to calculate the AH of neutralization for osphoric acid. Consider this the accepted value of AH. How does your experimental value or ΔΗ compare to the accepted value? Calculate the percent discrepancy between the calculated (accepted) value of the neutralization of HyPO and your experimental value. 5. AH of Ivanced Chemistry with Vernier 26-3
