0.12g of Mg was mixed with 20mL of HCl were mixed in a simple calorimeter. Two trials were conducted. In trial one, the initial temperature of the HCl was 22.0. While the Mg was added the temperature was 21.0 as well as rose to 43.50, leveling off at 43.0. In trial two the preliminary temperature of the HCl was 22.5. While the Mg was added the temperature was 24.0 as well as rose to 42.20, leveling off at 41.50.
Compute heat released by the reaction in each trial, the amount of Mg (moles) and ΔH1 (Mg/HCl reaction kJ/mole)
