1) when the temperature-time data graph was reviewed, it was found that the error had been made determining DeltaT. Instead of 4.76C, Delta T was actually 4.70C. Based on this change only, calculate the correct deltaH neutralization for the reaction oh NH3 and acetic acid. 2) calculate percent error if for correct Delta H (neutzn) if Delta T 4.76C had been used? <-----thew second question is what I want

2. Use the data of Part B for the reaction between NH3 (aq) and HCl (aq), and equation 2 to determine: AH for each run in kJ (AHA), AH per mole of limiting reagent for each run, and the average AH/mol of limiting reagent. Assume that the specific heat capacity of the solution is 4.184 J/gºC, the final volume is 100.0 mL, and the density is 1.03 g/mL. Show one sample calculation in the space below. Run # 1 Run...
