We gathered our evidence for part 1 in a data table as follows: Mass of anhydrous pellet (or powder) Mass of water (g) Initial temperature of water (°C) Final temperature of water (°C) TFinal - TInitial ΔTwater= Part 2. We gathered our evidence for part 2 in a data table as follows: Mass of hydrated crystals Mass of (g) Initial temperature of water (°C) Final temperature of water (°C) TFinal - TInitial ΔTwater= Section IV: Reasoning Our evidence [does support our claim because the theoretical change of / does not] enthalpy for both reactions combined is -104kJ, and our calculation is [insert overall ΔH Our percent error is [insert for both reactions shown above from conclusions, step 3].
