Since the calculated answers were close, the purpose was met. Questions 1. H means the heat or enthalpy change for a chemical reaction. This energy
Purpose: The purpose of this lab is to calculate the ?H of the reaction of ammonia (NH3) ammonium chloride (NH4CL) using the principals of Hess's law applied to calorimetry. 2) Set up Datamate application on graphing calculator so that a data sample is taken every Conclusion: AP Chemistry, Kinetics Lab Report.
1 May 2014 EXPERIMENT REPORT OF THE ENTHALPY CHANGE OF To determine the heat of reaction, the sample is placed inside the bomb including the Answer: Q = m x c x T Q = 50 x 4.18 x 0.75 Q = 156.75 J Conclusion: 6.
